Thank you for the sample!
I consider the following dark magic, it produces an
ac3 file that FFmpeg can decode but shows many
$ ffmpeg -i NOVA04012HDBA2x.mov -filter "channelmap=map=2-0|3-1"
-f s16be out.ac3
The ac3 file is stereo though, I would be very
surprised if it actually contains multichannel audio...
I don't know anything about professional television
transmissions, can you explain what this is / what
produces it / what uses it?
Thank you, Carl Eugen
