I used to apply a Dolby Pro Logic II encoding this way :

Actual command line and complete, uncut console output missing.


OK

ffmpeg -i test.mkv -map 0:1 -c:a aac -b:a 256k -af aresample=matrix_encoding=dplii -t 300 a.m4a


I was classicaly adding the "-ac 2" option, but now I'm not sure if it's a good idea and what to do to get the 2 DPLII channels without any further mixing.
