8f1de9ccd9 avutil/pixdesc: add alpha component information to pixfmts with reserved but undefined alpha bits 
This can be useful to simplify certain processes that need to know how many
reserved bits there are and where they are placed, even if they are ultimately
unused, as will be shown in the next commit.
For any other case where the user simply looks at nb_components components, it
will make no difference.

72e5381123 avfilter/vf_subtitles: Respect YCbCr Matrix header 
As specified in libass's ass_types.h, the colors or ASS_Images
should be converted to YCbCr using the matrix/range specified in
the track's YCbCrMatrix field (unless that field is set to YCBCR_NONE,
and defaulting to TV.601 if the header is missing).

This does not affect any subtitles generated or transcoded by ffmpeg,
since these contain a 'YCbCrMatrix: None' header.

242ee7b0a2 fftools/ffmpeg_sched: be smarter about flushing the pre-muxing queues 
These per-stream FIFOs hold the packets before every stream is
initialized and the header can be written. Once that happens, current
code will flush each stream's queue one after the other. However, in
case we buffered a lot of data for multiple streams, this may cause the
muxer to overflow max_interleave_delta, resulting in worse interleaving
than necessary.

Change the code to interleave packets from all the queues by DTS.
