The field is filled with the codec context information.

The field is filled with the codec context information.

FIXME need a minor version bump.

This will allow us to automatically generate manpages for them.

In most places where it's used, it's as a pointless write-only field.

Only rv10 decoder actually reads from it, but it stores some internal
version info in it. There is no reason for it to be in a public field.

- enable the options for audio encoding
- properly check for user-set maxrate
- use correct calling order in vorbis_encode_setup_managed()

Deprecate corresponding AVCodecContext field.

It's unused.

It's currently only used as temporary storage by the mov demuxer. Make
it use a local variable instead.

Deprecate corresponding AVCodecContext fields.

Deprecate CODEC_FLAG_CBP_RD.

Deprecate CODEC_FLAG_QP_RD.

Deprecate CODEC_FLAG2_STRICT_GOP.

Deprecate CODEC_FLAG2_SKIP_RD in favor of the corresponding mpv_flags
flag.

Also give a more suitable name to the MMI-optimized IDCT;
it is not PS2-specific, as the name currently suggests.

It is obscure, most likely unused and not bit-exact compared to
libavcodec due to a different IDCT transform algorithm.

Also increase the global limit on qmax.

This way, if the AVCodecContext is allocated for a specific codec, the
caller doesn't need to store this codec separately and then pass it
again to avcodec_open2().

It also allows to set codec private options using av_opt_set_* before
opening the codec.

It allows to check whether an AVCodecContext is open in a documented
way. Right now the undocumented way this check is done in lavf/lavc is
by checking whether AVCodecContext.codec is NULL. However it's desirable
to be able to set AVCodecContext.codec before avcodec_open2().

The old constants are more useful to the end user and have
orthogonal meanings to the new ones.

Using threaded decoding by default breaks backward compatibility if
AVHWAccel is used or if an appliction sets threadunsafe callbacks.
Avconv and avplay still use -threads auto if not specified.

Adds a new member to MpegEncContext to hold the number of used slice
contexts. Fixes segfaults with '-threads 17 -thread_type slice' and
fate-vsynth{1,2}-mpeg{2,4}thread{,_ilace} with --disable-pthreads.

A negative number of threads does not make sense and 0 is used for
autodetection. Adds a symbolic name for autodetection.

A new field, AVCodecContext.internal is used to hold a new struct
AVCodecInternal, which has private fields that are not codec-specific and are
used by general libavcodec functions.

Moved internal_buffer, internal_buffer_count, and is_copy.

libavcodec/options.c:583: warning: assignment discards qualifiers from pointer
target type
libavcodec/options.c:589: warning: initialization discards qualifiers from
pointer target type

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

This makes the code compile when FF_API_X264_GLOBAL_OPTS or
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.
