If using MFRA for timestamps, the stream may start from a large offset
and/or have gaps. With this change we calculate the bitrate based on
frames we've seen.

mov: Correctly check the color transfer characteristics range
Merged-by: Michael Niedermayer <michaelni@gmx.at>
This introduces a new option to the mov demuxer: -use_mfra_for
(pts|dts). When it's given and moofs and a MFRA are present, the MFRA's
TFRAs are read for fragment start times.
Unfortunately some programs that produce fragmented mp4s use the TFRA
time field for dts and some for pts. There is no realistic way to detect
which is the case, hence the responsibility is punted onto the user.
This also means that no behavioural change is enabled by default - you
must pass either dts or pts for anything to happen.
Without this change, timestamps for some discontinuous fragmented mp4 are
wrong, and cause audio/video desync and are not usable for generating
HLS.

syncframes in E-AC-3 can be combined to provide 6 audio blocks per
sample, thus requiring parsing for proper decoding.

Fixes regression from Ticket3962
This basically favors the first global header while since 34751f8313
it was the last. If this heuristic turns out worse, do not hesitate to revert this and
reopen 3962 as a feature request for multiple STSD

default-base-is-moof shall be set to track fragments compatible with DASH
Media Segments. So, this is a fundamental support for ISOBMFF ver. DASH.
This is meaningful only when base-data-offset-present is absent and two or
more track fragments are present in a movie fragment.

The '?xyz' form is used by android devices (and according to apple
mailing list archives, also by older iOS devices). The 'loci' field
(defined in 3GPP 26.244) is used by recent iOS devices.
Even though the loci field can contain an altitude, it was plain
0 in my sample. Just export longitude and latitude, in a string
format matching the one used by the '?xyz' metadata field.

Problem: ffmpeg tries to read COVR atom data twice if MOV_EXPORT_ALL_METADATA is enabled.
If COVR atom is the last in the stream, a parsing of such file fails.
Solution: just return immediatelly after mov_read_covr
