The change from BASELINE to CONSTRAINED_BASELINE is correct, but it bugs me a
little to hide it into this patch. Do you mind splitting it out ?
Note that these days, since we have no software fallback for it, GStreamer, and
probably FFMPEG too, still try out contrained-baseline decoders for baseline
content, as very often the bitstream does not actually uses FMO and ASO
features. So perhaps we can just edit this one out to help with merging this
set?
With one of these two fix:
