 As posted above and in the above console output, ffmpeg shows this red
 error on encoding the source dts:


 {{{
 [flac @ 00000000047178a0] Channel layout not supported by Flac, output
 stream wi
 ll have incorrect channel layout.
 }}}


 The eac3to developper said he will not add any warning when encoding with
 eac3to as there is absolutely nothing wrong with a 3/1 stream. So this
 should also be removed from ffmpeg.

 Furthermore, as I said above, 3/1 is supported by FLAC since version 1.1.3
 in 2006 with the WAVEFORMATEXTENSIBLE_CHANNEL_MASK tag.

 So it IS supported by FLAC, but not as one of the standard layouts, it is
 supported with WAVEFORMATEXTENSIBLE.

 Thanks.
