  • FFMPEG : How to extract multichannel track from m4v, mix it down and save the stereo downmix as "left" and "right" ?

    30 septembre 2015, par chillynilly

    just like the title already says : I want to extract a multichannel track (5.1) from an .m4v, mix this track down and save the output as separate files, so in the end I want to have something like ’downmix_left.wav’ and ’downmix_right.wav’
    I know how to do a downmix and I know how to split the audio, but I do not know how to do it in one step, which would save me a lot of time.

    This is the command I use for splitting :

    ffmpeg -i "video.m4v" -vn -filter_complex \
    
"[0:2]channelsplit=channel_layout=5.1(side)[FL][FR][FC][LFE][SL][SR]" \ 
    
-map "[FL]" video_left.wav \ 
    
-map "[FR]" video_right.wav \ 
    
-map "[FC]" video_center.wav \ 
    
-map "[LFE]" video_lfe.wav \ 
    
-map "[SL]" video_back_left.wav \ 
    
-map "[SR]" video_back_right.wav

    And this is the command for the downmix of a multichannel track :

    ffmpeg -i "video.m4v" -vn -map 0:2 -ac 2 \ 
    
-af "aresample=matrix_encoding=dplii" video_downmix.wav

    Is it possible to combine these and if so, how can it be done :D ? I would appreciate it very much if you could help me out here.
