The current behavior may produce a different sequence of packets
after seeking, compared to demuxing linearly from the beginning.
This is because the MOV demuxer seeks in each stream individually,
based on timestamp, which may set each stream at a slightly different
position than if the file would have been read sequentially.

This makes implementing certain operations, such as segmenting,
quite hard, and slower than need be.

Therefore, add an option which retains the same packet sequence
after seeking, as when a file is demuxed linearly.

Set this field to TRUE if the audio component is to operate on
little-endian data, and FALSE otherwise.

However TRUE and FALSE are not defined. Since this flag is just a boolean,
interpret all values except for 0 as little endian.

Sample-Id: 64bit_FLOAT_Little_Endian.mov

Prevents unsigned overflow and variable truncation.

This is a leftover from the static to dynamic vlc table conversion.

Instead check for all mov code-points when demuxing avi
and print a warning if a video codec is found like this.

Prevent a spurious read from uninitialized memory.

It uses 6 registers, unbreaks building on hardened x86 system.

As produced by Camtasia 4.

This is incompatible with the omit_tfhd_offset flag (writing
position independent fragments with interleaving requires the
default_base_moof flag).

This makes the moof atoms slightly bigger, but can be better for
playback (improving locality of sample data in the mdat).

This is needed if all the data for one track isn't continuous
within the mdat. Normally we make sure all the data for one
track is continuous, but in new cases we will need to have
the samples interleaved.

No global variables are used and the VLC tables are allocated without
static elements. This will allow using a JPEG decoding context within
other decoders.

This field is designed for marking codec properties useful to lavc internals.
Two internal capabilities are added:
 - FF_CODEC_CAP_INIT_THREADSAFE: codec can be opened without locks;
 - FF_CODEC_CAP_INIT_CLEANUP: codec frees memory if initialization fails.
