Can you at least fix regression of reporting stereo instead of mono in
ffprobe on original file, I gave regression commits? Also, why not drop
second channel from decoded multichannel wav? Also, AGAIN. Dolby decoder
(what do you use?) is not the reference! HW decoders '''are''' with Atmos,
original Mono.mlp is decoded perfectly on my LG C9 as mono. And the spec
says that you should also set all bits in
2ch_presentation_channel_modifier for mono. BTW, a question. What is
inside a fake second substream and why it was a good idea from the point
of view of Dolby?
BTW, I just got that LAvfilters are not yet updated with your timebase
44100 patch, so maybe that will fix MAT 2.0 bitstream timestamps and
desync on 44100 samples?
BTW, about last frame, are you sure your shorten_by is in the right
substream for mono?
