This allows it to use the defaults specified by preset/tune,
without overwriting it with the default value from the
AVCodecContext field.

FF_API_LAME_GLOBAL_OPTS is 0.

This function used to set codec_type. With the current fallback
implementation based on avcodec_get_context_defaults3, codec_type
won't be set to the value passed in, but will be set to
AVMEDIA_TYPE_UNKNOWN. Legacy callers of this function might expect
this field to be set to the value passed in.

If attribute_deprecated is used in an enum declaration, it
should follow the 'enum' keyword, otherwise it's ignored
silently. This is the only case of attribute_deprecated for
enum declarations currently.

Currently, this attribute_deprecated doesn't have any effect.
If moved to the right place, it emits a warning every single
time avcodec.h is included, like this:

avcodec.h:2827: warning: ‘AVLPCType’ is deprecated (declared at avcodec.h:543)

There is already a working attribute_deprecated for the
corresponding field in AVCodecContext, so therefore this
one shouldn't be needed.

It allows attaching arbitrary files, e.g. fonts to Matroska files.

The calling convention only allows 4 non-stack parameter, with each
float or int register being skipped if not used.

fixes memleak with raw gsm demuxing.

This keeps the streams sychronized. The packets must be interleaved per-DTS.

Add some parameters to existing function documentation.
Remove some unneeded documentation.
Convert some static function documentation to non-doxygen style.

This fixes a bug where the whole buffer was returned as decoded audio due to
*data_size not being set to zero and the return value being >= 0.

we only support decoding of mono imc

ask for a sample if not mono

Streams from RTSP or SDP that do not match an allowed type will
be skipped entirely, which allows video-only or audio-only
streaming from servers that provide both.
