1、正常MP4
sudo ffmpeg -i "rtsp://..." -c copy -f segment -strftime 1 -segment_time 20 %Y/%m/%d/%H-%M-%S.mp4
Could not find tag for codec pcm_mulaw in stream #1, codec not currently supported in container
Could not write header for output file #0 (incorrect codec parameters ?): Invalid argument

2、改为存储mkv
sudo ffmpeg -i "rtsp://..." -c copy -f segment -strftime 1 -segment_time 20 %Y/%m/%d/%H-%M-%S.mkv
