Hi Paul,

Yup, that helps. It now runs 64 channels at about 16x, that is about 20 times 
faster than before!

Where have I heard this before :-) (I won’t go there, no worries.)

This IS a serious problem, same as stripping audio only from video has become 
dog slow.
FFmbc used to be able to do that (with -c:a copy) at the speed of drive, FFmpeg 
nowadays seems to read the entire file, including video.

My filter compex is HUGE, it splits all inputs to mono, pads / merges / etc. 
(I’m doing auto sequence style.)
But for now, I’ve got something more to toy with.

Thanks,
Bouke

Better command line (way simplified) that indeed runs faster:
/Applications/ffmpeg -max_size 400 -i

[FFmpeg-user] Wave channel split is very slow

[Bouke / Videotoolshed]

Trying to split a 64 channel 48Khz 24 bits Wave file.
That is VERY slow.

ffmpeg -i /Volumes/Data/magweg/64channel.wav -filter_complex 
"[0]pan=mono|c0=c0[tr0]" -c:a pcm_s24le -map "[tr0]" 
/Volumes/Data/magweg/64_test/out_1.wav

Runs at about 15x

But if I do all 64 in one pass, it slows down to about 0.7x

I don’t get it. DiskIO should not be a factor, and there is no math involved. 
(Granted, the ppm_s24le might involve math, but that should be simple.)

Is this a bug? 
(Same happens vice versa, going from multiple non-interleaved to one big 
interleaved Wave.)

You are totally right, as you always are.
And you have such a nice way of bringing your point across, as you always make 
an effort to be friendly, and help people.

Now I’m stepping out of this.

Hi Eric,
Yup, this is the output of my (commercial) SpotXML app.
https://www.videotoolshed.com/product/spotxml/ 


Broadcasters over here have a Baton, an it eats the files.
(This particular one would be rejected cause having a non 5 sec multiple 
duration, and of course the volume change is very strange, resolution change 
probably not needed, I took the first stupid clip I found…)

Mind you:
Sometimes it’s wanted / needed to have all files ’the same’.
If that is interlaced, it’s interlaced. Codec should say ‘interlaced’, no 
matter the actual content.

For Avid media, that might (depending on the version of MC) be important for a 
‘fast import’, or omitting adapters you don’t want / need.

In broadcast, over here interlaced is mandatory, even if the content is 
progressive.

So no, it’s NOT complicated, and no, it’s NOT outdated.

[FFmpeg-user] Directshow capture and irregular timing of output to StdErr

[Bouke / Videotoolshed]

Trying to build a metering tool that displays (almost) RT values.
On Mac, all works fine with AVfoundation, but on Win with Directshow I have an 
issue:

C:\Users\Bouke>ffmpeg.exe -nostats -f dshow -ar 48000 -i audio="Line (Steinberg 
CI2)" -filter_complex "ebur128=peak=true" -f null -

Now, this works fine, BUT, the output to stderr is at very irregular intervals.
Output is as expected lines like:
[Parsed_ebur128_0 @ 01915fe77a40] t: 0.199979   TARGET:-23 LUFSM:-120.7 
S:-120.7 I: -70.0 LUFS   LRA:   0.0 LU  FTPK: -55.5 -71.0 dBFS  TPK: 
-55.2 -69.8 dBFS
[Parsed_ebur128_0 @ 01915fe77a40] t: 0.299979   TARGET:-23 LUFSM:-120.7 
S:-120.7 I: -70.0 LUFS   LRA:   0.0 LU  FTPK: -56.2 -72.7 dBFS  TPK: 
-55.2 -69.8 dBFS

Now, sometimes one line is outputted (as expected) but most of the times it’s 2 
up to 4 lines at the same time.
That does not make for a pretty visual show if I parse it ‘as fast as possible’

I could buffer the output and do my display stuff for each line with my own 
interval / if buffer line length >= 4 or alike, but that would introduce half a 
second delay, and that does not compute well in my brain when I have to ride 
the faders…

Is there anything I can do to have FFmpeg spit out each line ‘as soon as it is 
available’?
(I’m starting FFmpeg from Python, listening to StdOut / StdErr.)

Below the full command, what you cannot see is the irregularity in when the 
lines arrive….

Thx,

Bouke

Tried the following:

ffplay -f lavfi -i 
"amovie='\:2':f=avfoundation,ebur128=video=1:meter=18:target=-16 [out0][out1]”

Closer, but still no cigar:
It does not throw an error, but nothing is shown, as if input is not fed to the 
ebur128 filter

[FFmpeg-user] ebuR128 display of live source

[Bouke / Videotoolshed]

Hi,
Trying to get a visualisation of my levels during record / stream.
This works fine for file based material:

ffplay -f lavfi -i 
"amovie=/Users/bouke/Downloads/test.wav,ebur128=video=1:meter=18:target=-16 
[out0][out1]"

But I would like to have a live source (I’m on Mac, AVfoundation I guess.)

How to do that?

Re: [FFmpeg-user] Multiline subtitles without thin dark line

I would if I could, but sorry, that’s beyond my capability. 
For reasons like this, I render my own subtitles as PNG (with metadata), google 
’subbits subtitler’, that’s my work. (And yes, it allows for a box :-)

Then I create a catlist, and overlay, if a burn-in is needed.
Yes, that was quite some work, but I’m a control freak.

I hope someone else can help, I can’t…

I know, I just gave my opinion on how things “should” look. I come from a 
country where EVERYTHING is subtitled, and I’ve worked (as a pro in movies / 
tv) with subs for over 20 years.

You do not have a stupid black line, you have overlapping boxes so the alpha 
will double.
Increase line spacing and it ’should’ be fine. (I did not try, but I’m pretty 
confident.)
And for my taste, just outline is enough, boxes are ugly and came from stupid 
CC / TeleText.

I don’t get it.
Faststart is for internet / network playing only, when the entire file is not 
yet available.
If movflags faststart is needed, it should be darn fast as your files ’should’ 
be fairly small, as they are intended for (relative) low bandwith.
There is NO penalty for having the MOOV atom at the end if a file is local, as 
parsing all atoms will not take longer than a few secs if the file is local.
Having said that:
Checking the size of the moov atom is relative simple, use ‘any’ atom parser, 
or render the same file for 1 frame with a scale as small as you can get, with 
highly compressed sound and use the entire file size for the MOOV atom size 
(plus a bit).

Hth,

And for your next question that might come up (since you want to do multiple 
filters, I do too and just got bitten):
There is a limitation on Windows that won’t accept long arguments.
In that case, save the filter_complex string to a file, then, instead of 
filter_complex you can use filter_complex_script with the filename as argument.

Hi Ulf,
This is normal DV interlaced video. Open the .avi with VLC and turn OFF 
de-interlace, you’ll see how gorgeous the motion was on an old fashioned 
interlace aware screen.

So, you need to de-interlace the filter.
While you’re at it, you should crop a little, as SD is an over scanned format. 
And, you have non-square pixels that you have to accommodate for, so set aspect 
to 4:3 (in this case), or scale to a 4:3 ratio.

Hth,

Bouke

This I’ve never seen. I know that the TC is written as frames in Mov, Mp4 and 
MXF, so you need the frame rate to convert to HH MM SS FF
This sometimes goes wrong, so different apps calculate different TC values, but 
that is always the entire number doubled / halved.
In your case only the frames are doubled, this makes no sense, a frames to tc 
routine will not use a different FPS for hours / minutes / seconds and frames.

When you say ‘original File TC’, what makes you so sure that is indeed correct? 
What software tells you that? Did you try other apps? (Resolve / Premiere / 
Avid / Quicktime player / whatever you have.)

Definitely not crop, that will remove part of the image.
Instead, pillarbox it, using the pad filter, if needed in combo with scale.

Mind the codec copy.

If you omit that, FFmpeg will transcode, resulting in speed and quality loss.

Any half decent video editor / designer works with a GUI, WYSIWYG has been

Doing this without feedback only works in lab circumstances, and I think less

No, sorry. But, hire an editor / designer to do this for you, results will be

You do not specify what kind of output file size you want, so yes, it will be 
‘as it is’.
Having a .wav extension on your input DOES NOT mean your input is uncompressed 
Wave PCM. (Wave Can be compressed, in your case, you have OGG compression with 
a .wav extension.)

What do you expect / why are you doing this? The quality of your file will NOT 
get better, nor will the file size get significant down if you process it.

Concerning your lack of knowledge, the only thing you can accomplish is making 
things worse.

If you want to use the MXF/xxx folders, you need special wrapped Avid MXF.
The BBC has made a tool for that, https://sourceforge.net/p/bmxlib/home/Home/ 


If you have a recent version of Avid MC, you can use normal Op1 MXF, but those 
have to go to
Avid MediaFiles/UME/xxx

Both can work, I’ve done it before.

I think you are inserting black, not overlaying (blanking) the video. Try -vf 
overlay.
With -ss before input, it will do a faster search, you might have to do a bit 
of math on the enable= range, but that will become very obvious with a small 
test.

[FFmpeg-user] CRF and Preset in H265, am I loosing it?

[Bouke / VideoToolShed]

I’ve always thought that setting -crf [x] determines the output quality, while 
(in the same line) -preset [x] affected the output file size.
(Where faster speeds result in bigger output files at the same quality.

But now this:
https://trac.ffmpeg.org/wiki/Encode/H.265 


Under the Constant Rate Factor (CRF):

-Put differently, if you choose ultrafast, the encoding process is going to run 
fast, and the file size will be smaller when compared to medium.

WTF? I would think the output file size will be bigger? (I take it this is just 
a stupid mistake…)

Then, the line continues:
-The visual quality will not be as good. 
 
Now it gets confusing. This sorta kinda suggests that -crf and -preset are not 
to be used together?

What am I missing here?

Thx,

Bouke

[FFmpeg-user] rw_timeout trouble

[Bouke / VideoToolShed]

Hi all,
Strange issue:
Trying to transcode MXF ‘while in the making’ with the rw_timeout option.
It works on my end using Adobe Media Encoder for the MXF, but if Avid MC (on 
another computer that I don’t control) generates the MXF, 
the first video frame gets doubled, and a more than expected by the video frame 
doubled audio offset.

Below is the FFmpeg command (not the ‘real’ command, I use Python to fire 
FFmpeg, and that takes care of the quoting / escaping stuff, the line is a rip 
off from the list I send…),
and the (JSON) FFprobe output I use to generate the command line.

Clues?
Thx,

Bouke

What I do is xatrr -dr com.apple.quarantine (ffpath), and that seems to work 
just fine.

This is what it is about. the OP (Tangier) want to do a destructive change of 
TC on source files.
I’ve already told him that this is a problem now due to the changes in the OS 
(removal of QuickTime)..
Previous version of my work could do that with a plugin, based on the quicktime 
framework.
But that is gone. Now, ‘some’ QT’s have TC written as frame number in the 
beginning of the mdat chunk, but some not.
I can parse ‘some’ TC chunks, that tell me frame duration / frame rate and 
alike, but for the life of me I can’t find where the actual TC data is stored.
(And I can’t say I understand the Apple documentation.)

I’m pretty sure this is in the FFmpeg source code somewhere, but I can’t read 
C….

That’s probably FFmpeg work, but then there is no issue, as FFmpeg can easilly 
add a new TC when copying / transcoding to a new file.
The devil is in the destructive TC changing, but that is not something FFmpeg 
is supposed to do.

I don’t think this metadata is used. (And it’s incomplete as well, this is just 
a dump of the BEXT chunk that is not large enough to store all the metadata 
there is.
So, the names are completely irrelevant for FFmpeg. (And for everyone, as the 
good stuff is in the iXML.)
I must admit, have not tested it very well, but I would expect that there is a 
-ignore_metadata command as input option if it turns out I’m wrong here.

Not  an option, as what I’m making is intended to merge cam sound with external 
sound

Probably, but that’s beside the issue, it’s not up to me what end users want to 
map to where :-)

What DOES work as expected:
(Reverse mapping of BWF sound, with the last channel duplicated, reverse 
mapping of the two video sound channels.)
The channelmap from the BWF is a sum of (zero based) 2 to 12 from you list 
above, to leave room for the 0x3 (first two) for the video sound:

/Applications/ffmpeg -i /Volumes/Data/test/10track.wav -i

Hi Ted,
Ok, that’s what I’m seeing as well! (Now, I did not know that the track header 
contained this info, but indeed, the muted tracks show 0x02, setting them  
to 0x03 fixes the issue!
This is going to be my backup plan!

Not sure what version you are using but it does not on my end...
But, it seems easy enough to fix. (Although I still think this is a FFmpeg bug…)

Same muted tracks, but now I know how to fix them:

Now for the main course:

This looks promising, but I can’t grasp the filter_complex:
If I break it down:
> "[0:a]
Use sound from input 0

> channelmap=map=0-0|1-1
map channel 0 to output 0, channel 1 to output 1

> :channel_layout=0x6000,
I take it this is means the binary value, in this case 0 1 1 0 0 0 0 0 0 etc 
But this is output? (It looks like ‘max 32 channels out, use 1 and 2, leave 
room to insert the sound from the video at 0? And the mapping auto inserts the 
tracks to the first available slots? (Or how it is called…))

> [1:a]join=inputs=2
Use sound from input 1, start joining that, so total 2 streams input.

> :channel_layout=0x6002,
Now I’m totally lost. This states 0 1 1 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 0 0 0 0 0 
0 0 0 0 0 0 0 0 0
What am I supposed to see here? Start is the same, but then I’m lost...

> channelmap=map=0-0|1-1|2-2:
This also confuses me. The order of the second and third mapping looks likes it 
comes from the 0 1 1 yadda at the beginning.
But where is channel 0 from the second input mapped? Whatever I try, I always 
end up with channel 0...

> channel_layout=0x6002[out]”

Hi Ted,
Did you try it in Premiere, and got all the channels? Or open the output in old 
QT pro, and look at the properties.
The last channels are disabled. If I enable them and save the file 
(destructive), a new MOOV atom is added and the current one is flagged as FREE.
Then Premiere will accept it as it ‘should’ be.
(Warning, Premiere has  a nasty habit to ‘remember’ files. Once it has seen a 
specific file, it will use the properties of the first import, even when you 
change it and re-import.)

This gives me exactly the same issue.

Now, I can live with all the sound channels in one track, only reason I’m 
pursuing this is that I can’t remap more than about 8 channels into a single 
poly track.
(See my post from a few days ago…)

Nope, moving the  does not make any difference.

trust me, it does matter. First input file gets the audio enabled, all other 
gets muted in metadata.

there is no ‘normal’ in my world, and the Mov format accepts virtually 
unlimited channels in virtual unlimited tracks in virtual unlimited 
combinations, so that ‘should’ not be an issue.

SImpler in what way?
Sorry, but merging two files ‘should’ be possible IMHO, and I’m fighting on 
doing this for a couple of days now, so ‘simple’ is not in my book anymore.

[FFmpeg-user] more sound madness

[Bouke / VideoToolShed]

Hi all,
command below seems simple enough, and works, except that the last two audio 
channels (those coming from the second input) are muted in the metadata.
(Meaning, the sound data is there, but QT atom has flagged them as ‘inactive’.)

From memory, Carl once said when I had similar problems: ‘this is a known 
regression’, but that was ages ago.

What is the secret handshake to remap / patch / reroute / matrix / add / omit 
the sound channels of multiple input files to one new file?
(I can’t imagine I’m the only one doing this kind of stuff. And at this point I 
really don’t care if all the channels end up in one track, or in multiple, just 
to have them play in QT / Premiere and alike.)

Thx,

Bouke

Hi Carl,
I did, it is at the bottom.
(Well, it’s not really console, it’s what Python returns. I can’t get it to run 
from the console. I’ll try again though.)

[FFmpeg-user] Channel mapping misery

[Bouke / VideoToolShed]

Hi all,
Trying to do create files where I can control the audio channels. (From 
multiple, different sources.)

I’ve got it ‘sorta kinda’ working:

-threads 0 -i /Volumes/Data/test/C0092.MP4 -ss 1601.809541692 -i 
/Volumes/Data/test/068.WAV -map 0:0 -filter_complex 
[0:1][1:0][1:0][1:0][1:0][1:0]amerge=inputs=6,pan=6c|c0=c0|c1=c2|c2=c3|c3=c4|c4=c5|c5=c6[a]
 -map [a] -c:a pcm_s24le -timecode 01:42:38:10 -metadata:s:v:0 reel_name=C0092 
-c:v copy /Volumes/Data/test/C0092.mov 
(Full output at the bottom)
This works, although Wiki says ‘With amerge all inputs must have the same 
sample rate and format.’
But that does not seem to be the case… (In the docs in the -map_channel section 
it’s encouraged to use amerge, since -map_channel cannot do conversions…)
So, I don’t think my problem lies there.

When I add one channel more to the previous command: (the wave file has 10 
channels)

-threads 0 -i /Volumes/Data/test/C0092.MP4 -ss 1601.809541692 -i 
/Volumes/Data/test/068.WAV -map 0:0 -filter_complex 
[0:1][1:0][1:0][1:0][1:0][1:0][1:0]amerge=inputs=7,pan=7c|c0=c0|c1=c2|c2=c3|c3=c4|c4=c5|c5=c6|c6=c7[a]
 -map [a] -c:a pcm_s24le -timecode 01:42:38:10 -metadata:s:v:0 reel_name=C0092 
-c:v copy /Volumes/Data/test/C0092.mov -y 

This does show the pure channel mapping, but fails with:

[Parsed_amerge_0 @ 0x7facfcc28b80] No channel layout for input 1
[Parsed_amerge_0 @ 0x7facfcc28b80] Input channel layouts overlap: output layout 
will be determined by the number of distinct input channels
Assertion outlink->channel_layout == out_layout || !outlink->channel_layout 
failed at src/libavfilter/af_aresample.c:168

Then, adding yet another channel, the error message changes:
-threads 0 -i /Volumes/Data/test/C0092.MP4 -ss 1601.809541692 -i 
/Volumes/Data/test/068.WAV -map 0:0 -filter_complex

-c:v copy /Volumes/Data/test/C0092.mov -y

[FFmpeg-user] Strange TC on 50 FPS clips

[Bouke / VideoToolShed]

Hi all,
Getting strange TC readings on 50 FPS clips.
FFmpeg reports  timecode: 11:26:32:42
(And that corresponds with the frame counter in the start of the mdat atom.)

Premiere  reports   22:53:05:34
 QT 7 and Avid (older version)  22:53:05:17

Now Avid and QT have the habit of stepping trough the video by two frames if 
fps > 30, so that might be a hint.
(If I take FFmpegs TC to frames, (2059642) multiply that by 2 I’m at the 
‘correct’ frame number, converted back to TC it gives 22:53:05:34)

Now, is this a bug or am I missing something?

(Setting TC with FFmpeg has no issues as far as I’ve seen.)

If interested, the clip can be found here:
Download link 
https://we.tl/t-CP6GlfQIeG 
(Turn your volume down if you want to play it, it has loud LTC on the right 
channel.)

This makes no sense whatsoever.
I can provide  the time sample accurate. (Where a sample is 1 / 48000 if 
needed.)
I asked how to input ‘sync’ data, but have gotten no answer to that.

And,for other operations FFmpeg takes a float as input, and that sub-second 
accurate.

well, subframe accuracy if possible. I have time in samples from the audio,
Why do you think frame accuracy is not possible?

I meant, if the player shows a wrong playback time, what can I do then?

[FFmpeg-user] FFplay sync ext

[Bouke / VideoToolShed]

Hi all,
Seeking a way to slave video playback to an external clock.
(Meaning, jump to specific position and restart playing if the difference 
between current playback time and external clock is too big.)
Now, FFplay seems pretty simple, but I cannot find anything to control it 
besides the keyboard. Sending keystrokes seems awkward…

There is a -sync ext option, when I use that the video plays, and I notice a 
very small speed change in playback.
So what is ‘ext’ ?
Can I input something while playing? Where, what?

Or is FFplay not the tool for this?
(Using python / QT, any other options?)

Depending on your way of calculating,, the dividing might / might not be needed.
-ss is for the start of what you want, the -t stands for the duration of the 
file you want as output.

Give it a go a couple of times, you’ll see. (It won’t hurt.)

For the archives:
Do note that you perhaps meet the requirements of the GPL, you still may have 
to deal with other licenses if there is non-free stuff involved.
YMMV (IMHO)

Follow up:
I started testing last sunday, and for the life of me I could not reproduce the 
issue.
(My Windows did do an update that morning.)
Today the problem was back, and I narrowed it down to running FFmpeg.exe from 
(a subfolder) from the desktop.
I am totally clueless how this can happen. (The previous tests  from last 
sunday where the problem did not occur also was from the desktop.)
(Again, it’s a delay introduced before ANY transcoding, but no delay in 
starting FFmpeg itself.)
Same FFmpeg version run from another location is fine. 

Very, very strange.

Perhaps, but I can’t compile myself sadly.
I’ll see if I can get help somewhere else.

Nope, it happens on all input files.

[FFmpeg-user] Windows build starts slow on encoding

[Bouke / VideoToolShed]

Latest Zeranoe builds (Windows) have a very long delay before starting 
transcoding.
It seems not to be related on in/output codecs
-c:v copy is fast as usual, as is just getting metadata (omitting output), but 
anything else has a delay of about 10 seconds (at least) between spitting out 
the initial setup info and the actual start of encoding.

Below is a sample output, but again, it’s not related to the codecs afaik.

Thx,

Bouke

My gut feeling tells me that a custom scene detect setting will do the trick 
just fine.
but a -scene_detect=harding preset would be nice :-)

The OP may be referring to the Harding test.
(There was a Simpons episode situated in Japan where everyone but Homer 
suffered from the consequences.)
https://en.wikipedia.org/wiki/Harding_test 


A testfile that fails the test is here:

Hi Moritz,
Sorry for the late reply, just after testing this my laptop (where I performed 
the tests and have my e-mail) crashed, and my backup mail machine decided not 
to play anymore also,
I reverted to webmail, and missed some stuff here and there. (One of my 
accounts bounces a lot of mails from the FF list for some reason.)

I understood the original idea, and my tests as done were based on an actual 
existing input file, to see what happened with speed.

Thus, sadly, not on my system...

That could have been my issue, I’ve only toyed with ‘tail’

Let’s blame it on not using Bintail, but…

He should as it is intended for computer display or blowing up to HD, as SD is 
an overscanned format, so about 10% (to tast it seems) should be cropped off.
(Hence you see so many mics dipping in the image, these are NOT mistakes, but 
good practice to get the mic as close as the proper framing allows.)

[FFmpeg-user] amid fails when there are more than 8 input channels (in one file)

[Bouke / VideoToolShed]

Hi all,
Strange thing, more than 8 channels give silent output:

ffmpeg -i 9Ch_orMore.WAV -filter_complex "[0:0][0:0] 
amix=inputs=2,pan=mono|c0=c0+c1” -ac 1 mono.wav

gives on errors whatsoever, but output is silent.

Is this a bug or user error?

thx

Bouke

Hi Gyan,
AH! Stupid me, now I see only the unused channels (that go down the drain) are 
16 bits :-)
Thanks!

Hi Eric,
Great (I would never have come up with the way of disposing unwanted channels.)
One problem though, It seems that FFmpeg pipes the channel split, but does so 
in 16 bits:

  Stream #1:0: Audio: pcm_s24le ([1][0][0][0] / 0x0001), 48000 Hz, 7.1, s32 (24 
bit), 9216 kb/s
Stream mapping:
  Stream #0:1 (pcm_s24le) -> amerge:in3
  Stream #0:2 (pcm_s24le) -> amerge:in1
  Stream #0:3 (pcm_s24le) -> amerge:in4
  Stream #1:0 (pcm_s24le) -> channelsplit
  Stream #0:0 -> #0:0 (copy)
  amerge -> Stream #0:1 (pcm_s24le)
  channelsplit:FC -> Stream #1:0 (pcm_s16le)
  channelsplit:LFE -> Stream #1:1 (pcm_s16le)
  channelsplit:BL -> Stream #1:2 (pcm_s16le)
  channelsplit:BR -> Stream #1:3 (pcm_s16le)
  channelsplit:SL -> Stream #1:4 (pcm_s16le)
  channelsplit:SR -> Stream #1:5 (pcm_s16le)

And after that promote it to 24 bits again.
Is there a way to force the channel split to work in 24 bits?
(No idea how to squeeze pcm_s24le into the filter_complex part…)

[FFmpeg-user] Amerge trouble

[Bouke / VideoToolShed]

Hi guys,
Trying to do some audio patching from multiple input files, and output a QT or 
MXF with a poly soundtrack.
Now this turns out to be a hell of a job, I can’t grasp the logic on how the 
patching works.

Y\LTC_Convert\FF\ffmpeg -threads 1 -i V\!patch\test.mxf -ss 0. -i 
V\!patch\snd.wav -map 0:0 -filter_complex 
"[1:a][0:a:2][1:a][0:a:1][0:a:3]amerge=inputs=5,pan=5c|c0=c9|c1=c1|c2=c8|c3=c0|c4=c2[a]"
 -map "[a]" -ca pcm_s24le -cv copy -timecode 01:00:00:00 -y 
V\!patch\active\test.mxf"

FFmpeg returns:
Stream mapping:
  Stream #0:2 (pcm_s24le) -> amerge:in3
  Stream #0:3 (pcm_s24le) -> amerge:in1
  Stream #0:4 (pcm_s24le) -> amerge:in4
  Stream #1:0 (pcm_s24le) -> amerge:in0
  Stream #1:0 (pcm_s24le) -> amerge:in2

This looks all good, so the problem must be in how I define the pan, but for 
the life of me I can’t understand how the numbers work.
It seems (by other tests) that the input track up numbers based on what is 
already set, but it’s still erratic..

I would expect to get (output = from input file)
sndTrack 0 = snd.wav 2
sndTrack 1 = test.mxf 2
sndTrack 2 = snd.wav 1
sndTrack 3 = test.mxf 1
sndTrack 4 = test.mxf 3

but, the result has channels mapped as
sndTrack 0 = snd.wav 1
sndTrack 1 = snd.wav 2
sndTrack 2 = test.mxf 3
sndTrack 3 = snd.wav 1
sndTrack 4 = snd.wav 3

Isn’t there a simple way to set the patching? Or, where is my logic off?

thx,
Bouke

Ok, thx.
Is there a ticket? Should I send a bug report?
(I can fix it myself but would rather not be dependent on QT anymore)

[FFmpeg-user] Qt audio tracks muted

[Bouke / VideoToolShed]

When outputting QT with multiple audio tracks, on the first one is flagged as 
active.
Now I found this documented, and ‘should’ be fixed, but it’s still the case.
(And it’s bad, as Premiere ignores those tracks.)

Anything I can do?

[FFmpeg-user] Two frames trimmed of source start

[Bouke / VideoToolShed]

Hi guys,
Trying to do a simple transcode, but the output is missing 2 frames at the 
start.
I can live with that, but the timecode is then off by 2 frames as well.
How can I tell if the trimming will / will not occur so I can compensate the TC 
stamp?
(Or even better, can I avoid the trimming?)
thx,

Bouke

Guys,
Trying to listen to FFmpeg output, and ‘sometimes’ strange things happen.

On Windows 10, tried running FFmpeg from a batch file while redirecting the 
FFMpeg output to a file.
Then, during it’s work, my work copies the file to a fresh one, open it and 
read the contents.
When FFmpeg tells my work that it’s done, I try to delete the output.txt files.
However, sometimes they are locked. Any clues how that can happen?

Now, I switched to plan B. Shelling to FFmpeg and listen to StdOut.
(Ok, a more logical approach, but there was a reason for Plan A, don’t ask…)
This all seems to work fine, except that FFmpeg every now and then returns:
Exiting normally, received signal 15
(Here I've switched to Win 7 for testing)
But I’m pretty sure I did not send a cmd-Q or alike…
And it’s totally random when it happens. FFmpeg is just rewrapping ProRes QT 
with a bit of audio patching.

It’s not a biggy, as I can catch it and fire the same command again, but 
nevertheless I’d like to know what I’m doing wrong.

thx,

Bouke

AFAIK, only Reelname, Timecode and album / artist kind of entries can be 
changed, but not destructive, you have to generate a new file.

I was feeding 48K to the Mp3 echidna, and ‘sometimes’ it seems to choke on that.
-r 32000 made the problem go away….

This is a result of my front end that has to do a lot of stuff and be as 
versatile as possible.
It ‘should’ work (and it does, except for this audio codec, change it to 
pcm_s16le it works just fine…)

strange thing is, I did not notice this before, so there is ‘something’ strange 
with the input file.
No clue yet, and it only seems to happen on Mac.
I’ll dive into it tomorrow and try to pinpoint it more exactly.
(That will probably mean get other FFmpeg binaries)
As always, thanks for your help!

Hi Wolfgang,
Piping is a bad idea, it craps out after some 40 images in my experience. (Pipe 
to pipe to pipe to….)
What about creating a Cat.txt file first, and use that as input? That works for 
me just fine.
(Although the cat.txt is done outside FFmpeg…)

Re: [FFmpeg-user] Avid opAtom trouble

Subject: Re: [FFmpeg-user] Avid opAtom trouble



Hello

This probably happens because the ffmpeg MXF muxer does not write some
metadata that Avid expects.

Namely the following entries in the CDCI descriptor will be missing:
SampledWidth = 1920
SampledHeight = 1080

and this will be set (where 1920x1088 comes from):
StoredWidth = 1920
StoredHeight = 544

But the actual problem I believe is the missing metadata.

There is a patch floating around the mailing lists which fixes this (and
also same problem which happens where OP1a XDCAM HD files generated by
ffmpeg are imported into Avid editors).
https://ffmpeg.org/pipermail/ffmpeg-devel/2016-June/194830.html

Is there any reason why this patch is not accepted/applied?


Hi Jaka,
Is this a question for me? I can't answer it, just took the latest Zeranoe 
build...

thx,
Bouke

FFmpeg reports the frame size has changed from 1088 to 1080, and all is
well.

two filenames makes Avid refuse to import both, as it 'knows' it

[FFmpeg-user] Avid opAtom trouble

Am I missing something or is this a bug?

Next, what kind of metadata besides the clip name / timecode is supported?

[FFmpeg-user] OGG metadata

[Bouke / VideoToolShed]

Guys,
Got an OGG file that is supposed to contain timecode. (It’s generated for 
transcription.)
Output is below. Can someone shed some light on what I’m seeing? Is there 
indeed some time info there? If so, how to interpret it?
(The file indeed seems catted from multiple shots.)

thx,
Bouke

Aha! Jackpot. (I never had seen a LUT from the inside before…)
No clue if the output makes sense, but at least it’s doing ‘something’, and I 
can test!
Thanks for your help!

Re: [FFmpeg-user] Convert Audio Track To Numbers and Back

Not sure if FFmpeg can do this, but if you hire a coder he’ll be done in no 
time.
If the sound is uncompressed, it’s nothing more of finding the start of the 
actual sound data, and read the numbers.
Creating a sound file from numbers (uncompressed) is pretty easy too. (Although 
it’s your task to make it sound like ‘something’ .:-)

Now, since you want to do math on it, and you have already a nice format to 
store a couple of numbers (being X the position in the file, Y the value of the 
bits), why not stick to that as a file format as input? (And to plot, any half 
decent audio editor can plot a sound file…)

[FFmpeg-user] lut 3d trouble

[Bouke / VideoToolShed]

Hi guys,
Toying around on holiday, trying to apply a lut on OSX, having no luck.
Is it my FFmpeg version? (I’m on very limited bandwidth at the moment, no 
option to download a recent version for the next days…)
Any other stupid simple thing I’m missing?
thx,
Bouke

Huh? Uncompressed PCM seems easy enough to cat, and I have done so a zillion

Perhaps unrelated, but on my system, depending on the state of my machine (Eg 
if I have run Avid MC before), the output of my decklink is out of sync on 
known good sync input.
(No matter the player, it seems a Decklink driver issue.)
So you might want to test output with a known good local input file. (While 
looking / listening to Decklink output.)

Re: [FFmpeg-user] Need help generating field based Program Stream

[Bouke (VideoToolShed)]

- Original Message - 
From: "kumar vikram" 




Hello All,
I am having a Program stream which has progressive sequence. I want to
convert this stream to Field based PS files.

I have used the following command

ffmpeg.exe -y -i INPUT -c:v mpeg2video -flags +ildct+ilme -vf yadif=1 -top
1 -b:a 256k -aspect 16:9 OUTPUT

But this is creating Frame based interlaced stream.

Looks like I have missed some options. Can you please help me fix this
problem?


Hi Vikram,
What do you expect? If the source is progressive, an interlaced output will 
have two fields taken at the same time, thus still look progressive.
If the framerate does not change, besides doing this for being compatible 
with streams that must be interlaced, there is no reason to do so.
If you do want to change the framerate (eg from 50p to 25i, or add 
pulldown), there is logic. Have a look at the Tinterlace filter.

hth,
Bouke



Regards,
Vikram

Hi David,

Did you try adding a Reelname & Timecode? (And, a gotcha, don’t forget to quote 
drop frame timecode…)
And / or in combination with faststart.
I can’t remember having issues when this was all done. (But it’s some time ago 
for me…)

Did try latest build, and makes no difference.
I can send an input sample, but the only one I have is 2 gig, Is that a problem?

[FFmpeg-user] Sony FS7 AVC long group rewrap trouble

[Bouke (VideoToolShed)]

Hi guys,
Got trouble rewrapping Sony MXF clips to something else. (Main goal is to
change TC / alter sound a bit)
If I go to Mov, the result is a green image in both Avid and Premiere.
(Tried -vtag avc1 / aivx, but that seems to do nothing...)

If I go to MXF, the video is heavilly distorted / Premiere complains about a
gazillion errors.
VLC however likes the output just fine, but that's not good enough for rock
'n roll.
(Transcoding is not an option.)

Am I missing something, or is it just not implemented?

Bouke

I want to shoot video's with a green screen and then replace the green
part with a picture (not another video). How would I do that?


Hi Cecil,
You don't want to do this with FFmpeg.
Lighting a green (or blue) screen set is difficult already, and you want to 
have a zillion tools at your fingertips to get a decent end result.

Get a proper posthouse to do this for you. (I happen to run one :-)

Just a hunch, to stabilize you move the frame within is boundaries.
Crop filter after the deshake may be the answer...

[FFmpeg-user] Segment sound to multiple Waveform images

[Bouke (VideoToolShed)]

Hi guys,
Trying to split a soundfile to generate multiple audio waveform images.

ffmpeg.exe -i K:\test\test.wav -f segment -segment_time 8  -filter_complex 
"aformat=channel_layouts=mono,compand,showwavespic=s=640x120" -f image2 
K:\test\test_%03d.png


However, this gives me just one file, showing the entire duration of the 
sound clip. What am I missing here?


To make it slightly more complex, if this can be done, how can I make the 
last file to have the same timescale as the other ones?
(say the file is 12 seconds, the first image would show second 0 to 8, and I 
want the second one to be as wide, but have the audio data show only in the 
first half of the image.)


thx,

Bouke

Hi Carl,
I'm not the one behind that system. I've asked the guy who is if he can

(It was created for me to toy with, so I take it this is indeed 'as it is',

I'll let you know when I've got a definite answer. Here, direct or on the

[FFmpeg-user] Arvato proxy file

[Bouke (VideoToolShed)]

Guys,
Have a testfile that won't play nice.
This file comes from an Arvato asset management system.
AFAIK, it's a 'growing' file, that 'should' be playable while it's still 
being created.


FFmpeg (Latest Zerano build, ffmpeg-20160114-git-62dfe1d-win64-static) does 
not like it, and it tells me to upload a sample.
That i've done (Called Arvato_Proxy.zip), if there is no solution here, can 
someone please post this on the Develop list?


Thx,
Bouke

Some forms of TC just lack the space to store higher numbers IIRC (LTC / VITC, 
perhaps also in MpegII frame headers)
But there is logic in not going higher, as it is ‘time’.
For a real world use case, in the old days of tape, a reelname most of the time 
corresponded with the hour.
So a production with more than 24 tapes needed better administration in reel 
names that had to be written on the tape and box.

Re: [FFmpeg-user] Grab stills on scene change math question

Hi Moritz,
Thanks!


Hi Bouke,

assuming that gt(scene\,0.4) will return a number that I could do math

but this fails.


ffmpeg's expressions give the select filter a true/false (take or don't
take this frame) decision. In this case: scene detection shows a change
of 0.4 or more, principally.


Ah, that makes sense!


And to make it more complex, can I also grab a shot out of the middle
of a scene? (that would require to get the current and next
framenumber, subtract and divide by two to an integer and add to the
first...)


I wish I knew. I don't think such a filter exists. Part of the issue is
that ffmpeg would need to look ahead, and buffer a lot of data (which
it does for other filters as well).


Well, in theory it should only have to remember the last frame number...
But this is acedemic, as your solution is way easier.


What you could do is to parse the video for scene changes first,


Ok, this I can do.


calculate the images you want, and present them to the select filter in
the second run.


But, I'm clueless on how to do that?.
(Except restarting FFmpeg for each frame with a -ss)
Btw, is there a -ss  option that i can input frames instead of time?

Thanks,
Bouke

Subject: [FFmpeg-user] ProRes - MPEG2 bug: color shifting?



Hi,

I need helps for color shifting. Is it bug? or I am wrong with the usage?

I get a .mov file and its video format is ProRes 422, 24 fps, 1920x1080,
BT.709.
I put the MOV file in this mail as attachment proress_hq.mov, and only
one frame in this MOV.

Using ffmpeg to convert it to MPEG-2:
ffmpeg -i proress_hq.mov -c:v mpeg2video -b:v 30M -pix_fmt yuv420p my.m2v

I compared them by previewing proress_hq.mov and my.m2v in Edius and I
found there is a little color difference:
proress_hq.mov seems to be a small little brighter than my.m2v and the
color in my.m2v seems to be a little more saturate.


AFAIK, Edius uses Quicktime to decode.
There is a horrible bug in Quicktime that causes gamma shifts.
What you could try is to convert both your outputs to testfiles, both using 
the same codec/format.

Then compare those two. If they are alike, it's Edius that messes up things.

hth,
Bouke


How can i convert this mov to mpeg2 without color shifting?

Sure! There are few, but nice web pages about that. It seems this has
been a top hit on Google for the last few years:

https://irishjesus.wordpress.com/2010/10/17/blu-ray-movie-authoring-in-linux/

The ffmpeg/x264 parameters are probably still valid, as are the
caveats.

May I add: I have read that ImgBurn works fine using Wine (if you
happen to be on x86 and on a platform supporting Wine), and that it
supports UDF 2.6, i.e. proper Blu Ray mastering. I know ImgBurn well
from Windows, and it's an excellent ISO and burning tool, but I have
neither used it under Wine/Linux no for Blu Ray yet (but plan to -
both).

WARNING!
My last download of IMGburn came with an installer that installed A LOT of 
adware / browser malware.

IMGburn itself was good, but it took me a wile to get a proper system again.
