Transcoding only multichannel dsf files

[Veganfloyd]

Thank you, Simon. I got the ffmpeg package to work, but unfortunately the map_channel solution does nothing to solve the issue and adds some white noise.

I suspect that the problem may lie in not respecting the channel layout during transcoding or inability to read it correctly from dsf files. LFE needs to be skipped with 5 channel files. I think it may not be, which would make 5 channel files get transcoded to 4.1 with the side/back right speaker getting omitted. In support of this, 5.1 dsf files with silent centre and LFE get transcoded just fine.

I tried experimenting with the channelmap and pan options, always ending up with a syntax error. I would be grateful if you could please provide some pointers on how to incorporate these in Minimstreamer.
