Transcoding only multichannel dsf files

[simoncn]

It is possible the following might work:

ffmpeg -i INPUT -map_channel 0.0.0 -map_channel 0.0.1? -map_channel 0.0.2? -map_channel 0.0.3? -map_channel 0.0.4? OUTPUT

assuming FFmpeg recognizes five channels in the input, or perhaps

ffmpeg -i INPUT -map_channel 0.0.0 -map_channel 0.0.1? -1 -map_channel 0.0.2? -map_channel 0.0.3? OUTPUT

if FFmpeg only recognizes four channels in the input.

In stream.options, these would be:

convOut=-map_channel 0.0.0 -map_channel 0.0.1? -map_channel 0.0.2? -map_channel 0.0.3? -map_channel 0.0.4?

convOut=-map_channel 0.0.0 -map_channel 0.0.1? -map_channel -1 -map_channel 0.0.2? -map_channel 0.0.3?
