[FFmpeg-user] testing rtmp input

[Ricardo Kleemann]

Hi,

What would be the best way to test whether an rtmp stream is present?

I'm reading an rtmp stream as input and creating an mp4 as output.

But the stream isn't always present. I was thinking of doing a quick test
for stream presence, maybe reading 5 seconds of input as a test prior to
attempting the output.

thanks
Ricardo

[FFmpeg-user] audio noise filtering

[Ricardo Kleemann]

Hi,

I know almost nothing about audio filtering, and I wanted to better
understand more about it. I would like to filter out some low level
hum/noise from an mp4 file (h264/aac) and I understand there are different
types of filters, for example, a noise gate.

Can someone provide me with different configurations (command line syntax)
for noise filtering that I can experiment on the mp4 file and see the
results?

If it helps, the video is a recording from a church service (kind of like
an auditorium type location), and I was looking for ways to enhance the
audio.

Any help is appreciated

thanks

[FFmpeg-user] appending (or concussing) video on hls

[Ricardo Kleemann]

Hi,

I have two videos that I wanted to concat together. The end result is have the 
hls representation of the 2.

I already have one video in hls format, with the m3u8 playlist file and all of 
the ts files.

I wanted to append/concat a second video to the m3u8 playlist.

Is it possible to tell ffmpeg to simply take new ts segments and append to the 
m3u8 playlist? 

For example I can take the 2nd video and convert to hls segments, would ffmpeg 
be able to take the additional segments and just append to the m3u8 playlist?

thanks

Hi Flávio,

I'm not sure if this directly addresses your problem, but have you tried
using the -thread_queue_size parameter? I believe having a deeper queue
might help, the default value is only 8. I've used much larger values, even
2048 for example.

Granted, I think 2048 is overkill but I don't see any problem in setting up
larger queues.

[FFmpeg-user] ffserver: how to create ffm file anew each time a feed comes in?

[Ricardo Kleemann]

I’ve noticed that when I send a stream to ffserver, it keeps updating the ffm 
file if one already exists.

Is there a config such that the ffm starts anew when a new feed comes in? 
Otherwise I guess I would have to delete the ffm file?

[FFmpeg-user] ensuring output of #EXT-X-ENDLIST to m3u8 file for HLS

[Ricardo Kleemann]

Hi,

I have ffserver and ffmpeg working together to produce HLS streaming files.

Basically ffserver has an flv stream, and an ffmpeg process reads the stream 
and generates the HLS segments.

However, once the flv stream ends, ffmpeg doesn’t react to that by ending 
“cleanly” on its own. I’m forced to kill the process otherwise it just sits 
indefinitely waiting for input from the flv. The side effect is that the m3u8 
file misses the last line which typically contains #EXT-X-ENDLIST

Since I’m running the ffmpeg process in the background, I can’t cleanly “hit q” 
to quit it.

Does ffmpeg have a command option to cleanly exit (or timeout) if the input is 
halted for a period of time?

Alternatively, is there a signal I can send to ffmpeg for it to exit cleanly 
and it outputs #EXT-X-ENDLIST? 

thanks

[FFmpeg-user] help with live capture and audio sync issues

[Ricardo Kleemann]

Hi,

I have very inconsistent results with doing live capture. Sometimes the 
resulting file has perfect audio sync, but sometimes it doesn’t. I’ve tried 
different combinations but the results are never consistent.

I am capturing video from a black magic design UltraStudio Mini Recorder and 
the audio from an external Mic.

This is done on a MacBook Pro.

Here’s the capture command:

ffmpeg -y \
-thread_queue_size 2048 -f avfoundation -async 1 -i none:'C-Media USB 
Audio Device' \
-thread_queue_size 2048 -f decklink -vsync 0 -i 'UltraStudio Mini 
Recorder@12':none\
-c:v libx264 -preset veryfast -profile:v baseline -vf scale=640:360 \
-pix_fmt yuv420p \
-c:a libfdk_aac -b:a 80k \
-map 1:1 -map 0:0 \

 Alternatively you can edit the file in one operation if the desync can be
 fixed by adjusting the delay.
 
 *ffmpeg -i original.avi -itsoffset 0.2 -i original.avi -map 0:0 -map 1:1
 -acodec copy -vcodec copy **synced.avi*
 

I can try. The problem it’s not a fixed delay, the audio drifts.

Re: [FFmpeg-user] [SOLVED] taking audio and video inputs from different devices

Thanks Carl,

One of the things also that was happening was insufficient thread queue size. I 
was seeing this error:

Thread message queue blocking; consider raising the thread_queue_size option 
(current value: 8)

I’ve been able to get audio and video sync’ed properly, video coming from one 
input device and audio from the other as follows:

ffmpeg -y -thread_queue_size 512 -f decklink -vsync 0 -i 'UltraStudio Mini 
Recorder@12' -thread_queue_size 512 -f avfoundation -async 1 -i none:1 -c:v 
libx264 -preset veryfast -vf scale=720:405 -c:a libfdk_aac -ac 2 -ar 48000 -map 
0:1 -map 1:0 out.mp4

So far things seem to be working ok

 You could try to move -vsync 0 in front of the 
 first input.
 
 If this does not help, it may be possible to insert 
 the setpts filter to make the timestamp of the first 
 frame 0 (so it matches the audio starting timestamp).

I’m not sure where the crazy start time comes from, but yes, the audio works

Maybe I need to do something differently to mix the audio and video?

 Hello,
 
 Make sure you are using the good input format for your device. BMD is quite 
 touchy in that field.
 For instance, with a 1080i 50fps camera, I must choose the following format : 
 11 1920x1080 at 25000/1000 fps (interlaced, upper field first). If I use any 
 other, I also have the mire (vertical color bars).
 Do not hesitate to try all available formats. One of them will suit your 
 needs (typically 8, 10, 11 or 13 if you use a full HD camera / 14, 16 for a 
 screen grabber).
 
 If none of them works, I am not sure what to do in that case ;)

  https://www.blackmagicdesign.com/support/download/f3e35f03b97440c4893fdf7e0dfdf97c/Mac%20OS%20X)
  3) Install all dependencies for FFMPEG (use Brew as explained in the 
  FFMPEG compilation guide for Mac OS)
  — brew install automake fdk-aac git lame libass libtool libvorbis libvpx \
   opus sdl shtool texi2html theora wget x264 xvid yasm
  4) Download FFMPEG from Git
  — git clone git://source.ffmpeg.org/ffmpeg.git 
  http://source.ffmpeg.org/ffmpeg.git ffmpeg
   cd ffmpeg
  5) Prepare the configuration file (adapt according to your needs BUT 
  —enable-deckling is required for BMD). Adapt the path for your Decklink SDK
  — ./configure  --prefix=/usr/local --enable-gpl --enable-nonfree 
  --enable-libass \
  --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame 
  --enable-libopus \
  --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 
  --enable-libxvid --enable-decklink 
  --extra-cflags=-I/somepath/blackmagicsdk/Mac/include 
  --extra-ldflags=-L/somepath/blackmagicsdk/Mac/include
  6) If you use Mac OS X 10.9 or above, edit « config.mak »
  — vi config.mak
   Remove all references to « -std=c99 » (there are 2)
  7) Edit DeckLinkAPIDispatch.cpp (in /somepath/blackmagicsdk/Mac/include)
  — add the word static to the beginning of lines 56, 77, and 157
  56: void InitDeckLinkAPI (void)
  77: boolIsDeckLinkAPIPresent (void)
  157: void InitBMDStreamingAPI(void)
  8) Make  sudo make install
 
  Now that FFMPEG in installed with Decklink support, you can get the 
  audio-video stream from your BMD devices directly in FFMPEG.
 
  Use the following commands:
  ffmpeg -f decklink -list_devices 1 -i dummy
  ffmpeg -f decklink -list_formats 1 -i ‘UltraStudio Mini Recorder’
  ffmpeg -f decklink -i ‘UltraStudio Mini Recorder@16’ output.mov
 
 
  I was able to build ffmpeg with support for BMD.
 
 
  These commands are now all working and I get the set of formats supported.
 
  My problem now is that ffmpeg (and even ffplay) all they show is the 
  multi-colored vertical bars. If I run BMD Media Express, however, I see the 
  video coming from the camera. So something seems quite strange in how 
  ffmpeg is acquiring the source.
 
  I get the error of “No input signal detected”

 Hello,
 
 Make sure you are using the good input format for your device. BMD is quite 
 touchy in that field.
 For instance, with a 1080i 50fps camera, I must choose the following format : 
 11 1920x1080 at 25000/1000 fps (interlaced, upper field first). If I use any

 Do not hesitate to try all available formats. One of them will suit your 
 needs (typically 8, 10, 11 or 13 if you use a full HD camera / 14, 16 for a 
 screen grabber).
 
 If none of them works, I am not sure what to do in that case ;)
 

I thought the blackmagic device already provided H.264 in hardware, however it 
seems the drivers are seeing rawvideo. Do you know how to get h264 video?

 You can use both bmdtools (with pipe to FFMPEG) or decklink support for

[Ricardo Kleemann]

Hi,

I’m not having much success mixing in audio from the default audio input with 
the video. The video comes out fine but audio is basically inaudible with 
intermittent a little bit of static.

I don’t know if I have the proper settings, I do know that if I don’t use the 
async flag then the video plays back in very fast forward.

the avfoundation “none:1” would be to use the default built-in audio

Re: [FFmpeg-user] what program to use to grab device and send to ffserver?

[Ricardo Kleemann]

Thanks. I was thinking about that last night. With Flash Media Live
Encoder, the only one that works is the 1920x1080 60fps. I guess I'll have
to try each one and see.

 Hi,

 1) It is indeed the standard desktop video driver.
 2) You can unzip it wherever you want, just make sure you use the same
 path when you prepare the configuration file.
 3) You can make a « brew update » and « brew upgrade program » to make
 sure you have the latest version of all dependencies.


One curiosity... in terms of how you plan to use this, would you be using
ffplay to display whatever ffmpeg is processing? How do you plan on getting
visual feedback of whatever ffserver is processing from the BMD device?



 Have fun :)

  — git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg
   cd ffmpeg
  5) Prepare the configuration file (adapt according to your needs BUT
 —enable-deckling is required for BMD). Adapt the path for your Decklink SDK
  — ./configure  --prefix=/usr/local --enable-gpl --enable-nonfree
 --enable-libass \
  --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame
 --enable-libopus \
  --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264
 --enable-libxvid --enable-decklink
 --extra-cflags=-I/somepath/blackmagicsdk/Mac/include
 --extra-ldflags=-L/somepath/blackmagicsdk/Mac/include
  6) If you use Mac OS X 10.9 or above, edit « config.mak »
  — vi config.mak
   Remove all references to « -std=c99 » (there are 2)
  7) Edit DeckLinkAPIDispatch.cpp (in /somepath/blackmagicsdk/Mac/include)
  — add the word static to the beginning of lines 56, 77, and 157
  56: void InitDeckLinkAPI (void)
  77: boolIsDeckLinkAPIPresent (void)
  157: void InitBMDStreamingAPI(void)
  8) Make  sudo make install
 
  Now that FFMPEG in installed with Decklink support, you can get the
 audio-video stream from your BMD devices directly in FFMPEG.
 
  Use the following commands:
  ffmpeg -f decklink -list_devices 1 -i dummy
  ffmpeg -f decklink -list_formats 1 -i ‘UltraStudio Mini Recorder’
  ffmpeg -f decklink -i ‘UltraStudio Mini Recorder@16’ output.mov
 
 
  Thanks again!!
 
  I’m sure I’ll soon be writing with more requests for assistance ;-)

[Ricardo Kleemann]

Hello,

Regarding the options for config/compile, I didn't follow any specific set
of instruction or logic, I took a script used for building ffmpeg on a mac.
I can certainly change the script based on your helpful feedback.

More below...

 libfdk offers superior quality.

 From a quick look, this is unneeded (or isn't
 it?), I suggest you remove it.

  [AVFoundation input device  0x7fcd3ae00960] [0] Blackmagic Audio
  [AVFoundation input device  0x7fcd3ae00960] [1] Built-in Input

  The Blackmagic shows for Audio, but no for
  video.

 Which application that records the screen and the
 FaceTime camera is able to record Blackmagic video?
 What makes you think this isn't just a BlackMagic
 driver issue?


There's an app from Blackmagic (Media Express) which works fine with the
driver.

There's also the Flash Live Media Encoder (from Adobe) which recognizes the
blackmagic device and works well, so I can only assume the driver is
working fine.

Unfortunately neither ffmpeg nor VLC recognize the device so somehow to
these the driver isn't working, no idea why... :-/

Re: [FFmpeg-user] how do I list the devices?

[Ricardo Kleemann]

Thanks again for your help.

I’ve rebuilt ffmpeg and now I do see devices. 

But I don’t know how to differentiate. From the output below it seems to me 
there’s only 1 device which very likely would be the built-in webcam of the 
macbook pro. Which, if that is the case, then my thunderbolt device isn’t being 
recognized.

I do know that the capture device works, I can see it if I run the Flash Media 
Live Encoder application or the Media Express application that comes with the 
capture device.

The Blackmagic shows for Audio, but no for video. I tried to see if at least

captures the current screen (output to the screen/monitor)

I don’t know what the Input/output error at the end means… but I’m not able to 
get the Blackmagic video device unfortunately.

I know you’re not a Mac person, is anyone else able to help?

Sorry, it is Flash Media Live Encoder, and it does its own encoding and

I was hoping to not have to use FMLE and instead something that can push

Certainly I can feed the FMLE output to ffmpeg and then to ffserver but

I was hoping to go directly to ffserver, if for example ffmpeg was able to

[FFmpeg-user] ffserver - hls/segment options in ffserver.conf?

[Ricardo Kleemann]

Hi,

Anyone know if any of the segment (or hls) options used with ffmpeg can
be set for a Stream in ffserver.conf?

For example, hls_segment_filename, hls_time, etc...

I have a working hls file set of commands for ffmpeg but wanted to be able
to have ffserver produce a stream from that.

I've tried feeding ffserver using the -override_ffserver option in an
attempt to have the ffmpeg options passed over to the ffserver stream but
that's not working.


I tried setting up ffserver.conf with the following stream:

Stream live.m3u8
   Feed feed1.ffm
   Format hls
/Stream

And the command to feed ffserver is

$ ffmpeg -re -i ~/video/sample.mp4 -c copy -flags +global_header  -bsf:v
h264_mp4toannexb -hls_time 10 -hls_list_size 60 -hls_wrap 60
-hls_allow_cache 1 -hls_segment_filename

So when I feed this to ffserver, none of the segment/hls options take
effect, more importantly the ones with the filename paths. All I see are ts
files being written to the local directory where ffserver was launched, and
the m3u8 file is only written as .tmp and unable to be renamed

[FFmpeg-user] Does anyone have a working ffmpeg - ffserver config for hls/m3u8?

[Ricardo Kleemann]

I've been searching around the net found only a few examples but so far not
having much success.

My objective is to get a camera stream (available as input to ffmpeg as
m3u8) and feed it to ffserver, and play it out also as m3u8.

First, what I'm doing is simulating that by taking an mp4 file as input
instead.

Here's the info on the sample file:

 Hi,

 I'm trying to feed a stream (mp4 file) to ffserver via ffmpeg, and trying
 to access on ffserver and get the error:

 The ffserver config for testing is very simple:
 Stream live.mp4
 Feed feed1.ffm
 Format mp4
 AVOptionVideo flags +global_header
 AVOptionAudio flags +global_header
 /Stream

 (I've tried the test with and without the line VideoCodec libx264 with
 same results... when not having the line in there the objective is to copy
 the instream codec)

 When I startup ffserver this is what I get:

[FFmpeg-user] help with live streaming with ffserver

[Ricardo Kleemann]

Hello,

I've written a couple of messages last couple of days, and I'd say for now
ignore them.

I've been doing a lot of testing with many different configurations and
honestly I'm pretty lost on how to get this working...

I'm running a simple test... I'm simulating a live stream by reading a file
with ffmpeg and feeding it to ffserver. The file I have is mp4 with h264
and aac.

I want to be able to play it within an HTML5 video object by accessing
via http from ffserver.

So my first question... is this even possible, within video object and
http?

What would be the appropriate ffserver config and ffmpeg command line?

My current command line to feed ffserver is:

[FFmpeg-user] ffserver avc1 incompatible with codec id '28'

[Ricardo Kleemann]

Hi,

I'm trying to feed a stream (mp4 file) to ffserver via ffmpeg, and trying
to access on ffserver and get the error:

Sun May  3 09:18:25 2015 127.0.0.1 - - [GET] /feed1.ffm HTTP/1.1 200 4175
Sun May  3 09:18:32 2015 [mp4 @ 0x24edf10]Tag avc1/0x31637661 incompatible
with output codec id '28' ([33][0][0][0])
Sun May  3 09:18:32 2015 Error writing output header for stream 'live.mp4':
Invalid data found when processing input

The ffserver config for testing is very simple:
Stream live.mp4
Feed feed1.ffm
Format mp4
AVOptionVideo flags +global_header
AVOptionAudio flags +global_header
/Stream

(I've tried the test with and without the line VideoCodec libx264 with
same results... when not having the line in there the objective is to copy
the instream codec)

When I startup ffserver this is what I get:
