ffmpeg can not dump RTSP streaming but ffmplay can play
14 novembre 2018, par newBikeI want to dump the RTSP streaming into a file.
ffmpeg -y-i rtsp://172.19.12.37/live.sdp -acodec copy -vcodec copy tmp.mp4
But I got errors,
[mp4 @ 0x7fe98400dc00] track 1: could not find tag, codec not currently supported in container
Could not write header for output file #0 (incorrect codec parameters ?): Operation not permitted
However, I can play the RTSP streaming by any media player, what was wrong with my ffmpeg command ?
Is there any options can dump any stream and dump it into identical video format.
