Pausing ffmpeg stream
22 novembre 2020, par nmnirI'm running a client that reads video from a remote web cam :


ffplay rtp://127.0.0.1:1234



Sometimes the web cam stops and after a while it get back on. I need to be able to resume the stream even if the web cam was off for few minutes. Someone already asked that question on ffmpeg mailing list but didn't get any answer.

FFMPEG-PHP Error "Sample rate index in program config element does not match the sample rate index configured by the container."
21 novembre 2020, par JonathanAm using FFMPEG installed on a Windows server. I have a PHP webpage that uploads and trims videos using FFMPEG, when I upload MP4's with AAC audio, especially videos over 100mb, I get the following errors in the log output below.


I was wondering if anyone could point me in the right direction to getting this resolved.

FFMPEG recode clip1 to match clip2 for concat demux
21 novembre 2020, par Gert GottschalkI want to concat two video clips using ffmpeg concat. To use concat demuxer both should have same codec settings. clip2 is much shorter so I want to recode it to match clip1. Initially clip2 had tbn not matching and I adjusted that with '-video_track_timescale 50000'. Still the concat video after the cut into clip2 is garbled (audio seems OK)


This is what ffprobe tells for clip1 :

Then for concat :


/home/tools/bin/ffmpeg -f concat -i list.files -y clip12.mp4



The only gap is with
clip1 : 2080 kb/s
clip2 : 1553 kb/s


Is that significant ?


If yes, how to recode clip2 to match and result in concat clip12 being clean ?


EDIT (Per feedback from llogan) :


Probing input clips with latest ffprobe.

I'm observing mismatch in what I assume is the audio channel.


Clip1 :

Probably need to match audio channel. I noticed that the concat too a long time. I was expecting the concat to just do copying and not re-rendering.
