Minor suggestion below.

In addition, will sample file(s) be added to FATE? Below are two examples:

http://ffmpeg-imf-samples-public.s3.us-west-1.amazonaws.com/callout_51_l_c_r_ls_rs_lfe.mxf

Good idea, can someone with access please upload these to the fate mxf folder?

I suggest adding the following audio channels, which are specified in
SMPTE ST 2067-8 [1] and have a direct mapping to ffmpeg audio
channels:

urn:smpte:ul:060e2b34.0401010d.03020120.03000000 (Left Total) ->
AV_CH_STEREO_LEFT
urn:smpte:ul:060e2b34.0401010d.03020120.04000000 (RightTotal) ->
AV_CH_STEREO_RIGHT

[1] https://registry.smpte-ra.org/view/published/labels_view.html

Unfortunately this is a Dolby encoded stereo mix, not an ordinary LeftOnly / RightOnly mix. So I am not how this should be signalled.

Marton
