This will allow decoupling the parser from the decoder.

It is no longer necessary after 741b494fa8

It has nothing to do with the reference count and so does not belong in
this function.

Remove now unused ff_h264_decode_nal().

Just pass through the bitstream as is. This is the same as what is done
for HEVC already.

Add a flag which applies here, which had been missed.

This muxer generally handles pts == NOPTS by using dts instead;
do this for consistency here as well.

This codepath isn't quite as bad as it used to sound, if fragments
are cut automatically at video packets.

And use it for the separate-plane side-feature as well.

Avoid the clang warning

"warning: shifting a negative signed value is undefined"

Avoid the clang warning

Modifying global header extradata in encode_frame is an API violation
and only happens to work currently because mov writes its header
at the end of the file.

Heavily based off of a patch from 2012 by Nicolas George.

The h264/hevc Annex E colour primaries table says that AVCOL_SPC_SMPTE170M is
similar than AVCOL_SPC_SMPTE240M. These two values are not similar than
AVCOL_SPC_BT470BG.

Right now they are the first encoders for those codecs in the list, so
they are selected when the caller requests a codec by id.
Since they require special treatment, they should not be selected by
default if there are other encoders (e.g. libx264/5) available.

This can only be used if the input data happens to be laid out
exactly correctly.

This might not be supported on all encoders, so only enable it
with an option, but enable it automatically on raspberry pi,
where it is known to be supported.

The raspberry pi uses the alternative API/ABI for OMX; this makes
such builds incompatible with all the normal OpenMAX implementations.
Since this can't easily be detected at configure time (one can
build for raspberry pi's OMX just fine using the generic, pristine
Khronos OpenMAX IL headers, no need for their own extensions),
require a separate configure switch for it instead.

The broadcom host library can't be unloaded once loaded and started;
the deinit function that it provides is a no-op, and after started,
it has got background threads running, so dlclosing it makes it
crash.

This avoids spurious library rebuilds when only the test program
code is changed and simplifies the build system.

Restore alphabetical order in lists, break overly long lines, do some
prettyprinting, add some explanatory section comments, group parts
together that belong together logically.

Due to how pixel format conversion is done, they behave the same way
as gray files.

The first byte contains compression level together with keyframe status.
When a frame is not interpreted correctly, its data is summed to the
reference, and would degrade over time, producing an incorrect result.

The current sample comes from an older version of the codec, which
supports a single output mode, so rename it accordingly.
