Since an AVFrame now has malloced members (extended_data), it must have
a destructor.

AVFrame is used for both audio and video, so calling the argument 'pic'
is misleading.

AVCodecContext.encode is currently used only for subtitles, encode2 is
used for audio and video.

This function was deprecated two major versions ago (2009).

Japanese DTV uses some non standard extensions in AAC audio.
One example is 'dual mono', which combines two independent
audio into one stereo stream, storing them in left and right channels
respectively.  Historically, dual mono audio has been used for
multi-lingual audio, one for local/native language, and another for english,
and usually the "main" (local language) channel should be output without
any user interactions.

The frames of those dual mono audio are allowed to set
ADTS channel_config field to 0, and just contain two SCE's *WITHOUT* PCE,
which is a non standard extension by Japanese DTV standard.
(ref. ARIB STD-B32 PartII 5.2.3)

This patch adds an AVPacket side data, AV_PKT_DATA_JP_DUALMONO,
which indicates that the AVPacket is likely to contain an audio frame
with the above dual mono extension, and has the parameter to specify
the desired channel selection in that case.
It also makes aacdec to detect dual mono and output just the desired
channel when this side data is attached.

The cpia video decoder is intended to be used with the v4l2 demuxer.
There are some small changes to the v4l2 demuxer to support the
variable frame length of the format.

The special cases in demuxers and decoders are a mess otherwise (and more
would be needed to support it fully)

After various discussions, we concluded that, amongst other things,
it made sense to have a separate subrip decoder that did not use
in-band timing information, and rather relied on the ffmpeg level
timing.

As this is 90% the same as the existing srt decoder, it's implemented
in the same file.

They describe properties that are inherent to a codec (as described by
an AVCodecID) without referring to a specific implementation.

C++ does not allow to mix different enums, so e.g. code comparing
ACodecID with CodecID would fail to compile with gcc.

This very evil hack should fix this problem.

This is required otherwise it is not always possible to guess the number
of channels from the layout, for example if the channel layout is
unknown.

This patch also introduces CODEC_ID_OPUS.

Slightly more readable, now that the list is getting longer.

The number of pixel formats outgrew the number of available bits in
the bitmask used in avcodec_find_best_pix_fmt().
avcodec_find_best_pix_fmt2() uses a PIX_FMT_NONE terminated list
of pixel formats instead.

The numerical values of the profiles are the MPEG4 Audio Object
Type values, minus one.
