The problem occurs in slice quant estimation and slice encoding:
If the slice quant is larger than MAX_STORED_Q we don't use pre-calculated
quant matrices, but generate a new one, but both qmat and qmat_chroma both
point to the same table, so the luma table ends up having chroma table
values.
Add custom_chroma_q the same way as custom_q.

Binary searching would hang if the fragment items do NOT have timestamp for the
specified stream.
For example, a fmp4 consists of separated 'moof' boxes for each track, and
separated 'sidx' for each segment, but no 'mfra' box. Then every fragment item
only have the timestamp for one of its tracks.
Example:
ffmpeg -f lavfi -i testsrc -f lavfi -i sine -movflags dash+frag_keyframe+skip_trailer+separate_moof -t 1 out.mp4
ffmpeg -ss 0.5 -i out.mp4 -f null none
Also fixes the hang in ticket #7572, but not the reason for having
AV_NOPTS_VALUE timestamps there.

Bad content may contain stsc boxes with a first_chunk index that
exceeds stco.entries (chunk_count). This ammends the existing check to
include cases where chunk_count == 0. It also patches up the case
when stsc refers to unknown chunks, but stts has no samples (so we
can simply ignore stsc).

Detecting missing tfhd avoids re-using tfhd track info from the previous
moof. For files with multiple tracks, this may make a mess of the
avindex and fragindex, which can later trigger av_assert0 in
mov_read_trun().
