Hello, I'm recording command line ffmpeg samples using a command such as: ffmpeg -i rtsp://user:[email protected]/axis-media/media.amp?resolution=1280x720 -c copy -map 0 -use_wallclock_as_timestamps 1 -reset_timestamps 1 -f segment -segment_time 20 -segment_format flv "capture-%03d.flv"
When I do, the 1st segmented file always seems broken, but the rest are fine. They are broken when I try to play them with VLC and also when I try to call "avformat_find_stream_info" using code. This only seems to happen if I both record it as flv and as segments, if I use mp4 or not as segments.. works fine. Have tried with multiple rtsp streams, all have the same problem. Some interesting error message output when I call some ffmpeg functions: avformat_find_stream_info will give me: [flv @ 000001b767a4db40] Video codec (0) is not implemented. Update your FFmpeg version to the newest one from Git. If the problem still occurs, it means that your file has a feature which has not been implemented.
