Hi,

 

>From a rtsp flux (1 video stream + 1 audio stream), I would like to record 3
files: 2 video files containing only the video stream (corresponding to left
and right parts of the video) and 1 audio file containing only the audio
stream (mono).

My command is doing something but the left file is containing the full size
video and according to its size also probably contain some audio (not
detected by VLC reader), can you help me please ?

Thank you in advance
