This is a utility function for the user to get the frame duration based on
the codec id, frame size in bytes, and various AVCodecContext parameters.

Useful to return instead of -1 when the cause of the error is unknown,
typically from an external library.

This library does not fit into Libav as a whole and its code is just a
maintenance burden.  Furthermore it is now available as an external project,
which completely obviates any reason to keep it around.

This will allow parsers to export the duration of the current frame being
output, if known, instead of using AVCodecContext.frame_size.

This makes it possible to dintinguish them from PAL8.

Fixes an invalid write in avpicture_layout().

Deprecate avcodec_encode_video().

Factorize code and provide ratio parsing consistency.

Wrapper around av_fast_malloc() that keeps FF_INPUT_BUFFER_PADDING_SIZE
zero-padded bytes at the end of the used buffer.

Fixes bug 212.

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 functions are already av_ prefixed and intfloat header is already provided.

There was no minor bump for making avcodec_alloc_context3() public and
deprecating the other two, so I'm using the first next lavc bump.

The lavf-ffm test results change because ffmenc writes
AVCodecContext.flags/flags2 and the defaults for those change.

This was intended as an optimisation for skipped blocks in MPEG2
P-frames and never used elsewhere.  Removing this "optimisation"
speeds up MPEG2 decoding by 1-2% (ARM Cortex-A9).

It sets the supplied AVFormatContext pointer to NULL after freeing it,
which is safer and its name is consistent with other lavf functions.

Also deprecate av_close_input_file().

Deprecate avcodec_decode_audio3().
Implement audio support in avcodec_default_get_buffer().
Implement the new audio decoder API in all audio decoders.

Add AV_NUM_DATA_POINTERS to simplify the bump transition.
This will allow for supporting more planar audio channels without having to
allocate separate pointer arrays.

Based on code by Stefano Sabatini.

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.
