My original post explained how to determine where the runs of black are, using 
ffmpeg (libavfilter)'s "blackdetect." The only piece left is applying the edits 
in a practical fashion.

Rolling your own with opencv would be a whole lot more work. I'm not entirely 
sure that I agree with Carl Eugen that ffmpeg isn't a video editing tool, but 
if it's not, Python certainly isn't. Yes, you can make it work. But you're 
going to spend a lot more time doing it than if higher level tools were used.

The goal here is for higher-level tools, not lower-level ones.

Or I might just end up using ffmpeg to split it into 7,000 files and then 
concatenating them. That's hardly the worst thing in the world.

I suspect that most of the opensource editing projects use them. I've 
dabbled with ShotCut, and it seemed OK. I also suspect that they're not 
going be much of a help (need EDLs and all that).


An option, perhaps not very good, is to split the existing video into one 
file per quadrant, process the one with the dropouts, then recombine into a 
single video. If you have the space, the intermediate files could be 
uncompressed so as to lessen quality loss along the way.

But why should it abort if the extradata is not valid but unneeded?

[FFmpeg-user] wrong extradata on decoding a mxf xavc long gop file.

[Yufei He]

Hi

https://drive.google.com/open?id=1Rugz-tKCNDViN-zxJ9pQyKqSi_Eos7QD

On decoding the file this link, avctx->extradata is wrong data, there is no 
valid sps and pps.

Actually, mxf files does not need extradata. normally  sps and pps are stored 
in every IDR frame.

My decoder expects right extradata.  Yes, I can add protection to check if it's 
valid.

I debugged with h264dec.c, it can not find valid sps pps either.

Regards.

Yufei.

[FFmpeg-user] How to restart a fmmpeg frozen stream

[Sergio A S de Aguiar]

Dear friends:

I am working in a transcoder to capture a camera stream and transcode it to 
send a multibitrate encrypted stream.
So far, so good.
The problem is that sometime the stream crashes and keep sending black frames 
(or the some frozen frame continuously), so the ffmpeg is running but there is 
no image (just the black stream or the frozen frame, as I stated).
The imput is working.
I think this can be caused by some momentanous problem with the input stream 
wich makes ffmpeg loose the sync.

I want to detectt when the output frames doesn't change and restart the bash 
script wich is using ffmpeg.

At this time I am using a compex filter to detect when there is no change of 
the frames for the last 20 seconds (600 frames).

This is the script:

#! /bin/sh

echo "Starting cam1frozen" >> /mnt/sdd/html/frozen.log
/mnt/sdd/html/./CAM1FROZEN -y -hide_banner -loglevel warning -threads 0 \
-i "rtsp://192.168.1.100:554/live/ch00_0" \
-filter_complex 
"select='not(mod(n,600))',select='lt(scene\,0.06)',drawbox=y=ih-h:color=black@0.4:width=iw:height=48:t=fill,drawtext=fontfile=/usr/share/fonts/truetype/ttf-bitstream-vera/Vera.ttf:fontsize=40:fontcolor=0xAAFFAA:text='No
 Movement':x=10:y=h-th-10" \
-vsync vfr /mnt/sdd/html/hls/live/CAM1/frozen/frozen_CAM1_%06d.jpg \
>> /mnt/sdd/html/frozen.log 2>&1 &

Obs: The CAM1FROZEN  is ffmpeg renamed so it's easy to find usinf ps.

It is generating the jpg files, as expected.
Now the question: How can use this to execute an external bash script wich will 
kill and restart the capture script?

Thanks for your help

No. Errors are human. Your behaviour is not adequate. Trying to justify
it makes it worse. The OP apologized. You should do the same and move on.

I could mention your spelling errors, for instance, but I will not.

I think the difference comes from which stream connects first and starts 
receiving packets first, since there’s no reference time to sync both streams 
to.

Many (most?) devices of this kind also transmit the absolute timestamps 
separately from the video stream, so if you have the system time synchronized 
on both cameras, perhaps using ntp, maybe it would be possible to use this 
information to sync the two streams up but i don’t know if it is possible to do 
this automatically using ffmpeg alone.

Nothing seems out of order, what did you mean when you said “destroy a good cbr

missing something though, what did you intend for your batch file to do?

No, please, don't do this.

This would be "hijacking a thread" and start another tirade, and we
don't need that, do we? ;-)

(Besides, this is not a forum, but a mail list, it can not be resorted

In practical terms, it hides your question inside another thread, and
one that people are trying to avoid.

Instead, post a *new* email addressed to the list, with your subscribed
email (don't use "reply" then change the subject or erase the content;
use a real new email), add a proper indicative subject and write your
question.

And when replying, use quoted replies (like mine here), not top posting,
or you will start another tirade ;-)

Hi there FFmpeg team,

I'm hoping someone can help me with what I thought would be really simple
but I've been battling for days. I need to keep ffmpeg "alive" even if the
source or destination drops.

The added issue is I'm using ffmpeg on tiny core linux on raspberry pi as :

libswresample   2.  1.100 /  2.  1.100
libpostproc54.  0.100 / 54.  0.100

In short my current command is :

sudo /DerMixD/bin/dermixd -c default_output=raw_s16
default_outfile=/dev/stdout -r main.unix=n main.socket=localhost
main.port= | FFREPORT=file=/tmp/ffreport.log:level=24 ffmpeg -nostdin
-re -f alsa -ac 2 -f s16le -i /dev/stdin -f alsa -acodec aac -b:a 64k -af
"aresample=44100" -f flv -rtmp_live live rtmp://
vetsak2.antfarm.co.za:1935/ant-l-caxton/99lpfkm &

This command starts an audio daemon that our application feeds instructions
to. This is called DerMixD - Essentially this feeds /dev/stdout and pipes
the data to ffmpeg.

ffmpeg then feeds the stream to a rtmp server.

The issues I'm having are that if my feed from dermixd stops (EOF) for even
1s, ffmpeg falls over. Further, this then causes a condition on dermixd
that the feed from dermixd then runs into /dev/stdout too fast.

The same issue happens on the other side that if the ingest point drops for
even 1s, the feed from ffmpeg stops and inturn causes dermixd to fail.

I know this is a long shot as my setup I guess is rather unique but how can
I keep ffmpeg "alive" and almost just waiting for the stream to start
again? Essentially this is a restream from local dermixd > rtmp server. But
the dermixd feed can stop / start and the rtmp server could also loose
connection and come back.

ANY help or ideas would be awesome as the normal -reconnect commands etc
are not in this version of ffmpeg.

Thanks and chat when you can.

Hi Paul,

Thanks for responding. Actually, I'm getting replies from many people and
It's too much confusion. Individually, I can't reply to everyone. I started
following Ted Park. What all information required you required.

regards,
Saurav

[FFmpeg-user] recording video file with 2 video tracks of two live cams

[sekret]

Hi guys,

I'm new to this mailing list and I just subscribed because for the first time I 
have a problem with ffmpeg I cannot solve by myself. Hope I'll get some ideas, 
maybe solutions here.

What I need to do is record a video with 2 video tracks of two live 
surveillance cameras, connected by ethernet. Both can be accessed with rtsp. 
The first of the two cameras has a mic connected. The command line I've come up 
with so far looks like this:

ffmpeg -i "rtsp://$USERNAME:$PASSWORD@192.168.234.34:554" -i 
"rtsp://$USERNAME:$PASSWORD@192.168.234.33:554" -map 0:0 -map 1:0 -map 0:1 -c copy "$(date 
+%Y%m%d%H%M%S)".mkv (I don't think I need to explain, right?)

This works very well, both on my Linux laptop (Archlinux) and a Windows 10 
desktop. Both have version 4.1.2 of ffmpeg installed.

BUT: The videos aren't in sync. The audio and video of the first camera are 
perfectly in sync (obviously, since the mic is connected to the first camera), 
but the second camera's video track is about 1.3 seconds ahead.

So, my questions are:
- Is this command line of mine too primitive for this to work properly?
- Is there a way to sync the video tracks? Maybe to delay the first one by 
those 1.3 seconds?
- Is there a different approach which potentionally works better?
(- Does maybe one of you guys happen to know a perfectly working software for 
this?) (I've searched and searched ... It's not a typical use case for 
surveillance cameras, so no success)

Best
sekret

It seems he was trying to follow them, but made a mistake. If you’re

still here, you need to email ffmpeg-user-requ...@ffmpeg.org , not the mailing list itself dbenari

what mistake can you make in case of "email

Please do not be so insulting


you have no idea how insulting sounds!



Your comment is not helpful

but yours as?

No, being offensive doesn't help. Everybody deserves a polite response. 
If you do not feel like answering simple questions in an adequate manner 
then just don't post one.

Tobias

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:

(Sadly, i have no ide where it fails, it is not per definition the strobe shots 
at the end.)
