It can happen after 5 min or 55 min into the recording... The shortened videos are playable but suddenly end without warning. I extended my download script so it will check after ffmpeg exits if the set time has been reached or if it is more than 2 min short. If it is short it modifies the output file name by adding extension .x.mp4 instead of .mp4, then it waits for 60 s and re-launches the ffmpeg command. I log it too so I can see that it has triggered but no video file appears from this call so I assume that the problem persists for longer than the minute I wait... In my log I see that the extra ffmpeg call has been executed 5 times since April 22, when I modified the script. But no "rescue" video appeared so I guess at these times the outage was longer than 60 seconds. When the next recording started the following hour it usually worked. Since I am unable to simulate the problem I think I have just to give up for the moment... -- Bo Berglund Developer in Sweden _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
