Thanks, I am trying to do that with -af instead of -vf (is that right?)
but receiving no audio output.
{{{
ffmpeg -i "audio_channel_mapping_issue_2_22.mxf" -map 0:v -y -c:v
mpeg2video -s 1920x1080 -video_format pal -profile:v 0 -level:v 2 -r 25
-aspect 16:9 -flags +ildct -b:v 50000k -minrate 50000k -maxrate 50000k -af
"[0:a:0][0:a:1]amerge,pan=7.1|c0=c0|c1=c1" -acodec pcm_s24le OUTPUT.mxf
}}}
I am probably forgetting about something here. Sorry, I have not
encountered panning in ffmpeg yet.
