It allows to check if a given codec can be written into a container.

The new function provides a more flexible interface for peeking at a
FIFO buffer data.

The list type was changed to int64_t to be able to hold
channel layouts.

avfilter_make_format_list() still takes a int32_t array and converts
it to int64_t. A new function, avfilter_make_format64_list, that
takes int64_t arrays has been added.

Also add the public interface libavfilter/vsink_buffer.h.

This is required for letting applications to create and destroy
AVFilterInOut structs in a convenient way.

Make it returns the list of open inputs and outputs, so it can be
reused by applications.

Breaks API/ABI.

Since some minor bump were not done, some entries present the same
libavutil minor (which represent the next bump after the corresponding
change).

Remove duplicated entry regarding PIX_FMT_BGR48LE/BE formats.

Rename it to AVDictionary, since it will be used as such.  Tags
documentation and metadata conversion API is lavf-specific, so remains
there.

Deprecate av_get_bits_per_sample_fmt(), which was a misnamed function.

For the moment we don't have sample formats with a non-integer number
of bytes, in that case we may need to create a new
av_get_bits_per_sample() function. In the meanwhile we prefer to adopt
this variant, since avoids divisions by 8 all over the place.

Remove AVFilterBufferRefAudioProps.size, and use nb_samples in
avfilter_get_audio_buffer() and avfilter_default_get_audio_buffer() in
place of size.

This is required as the size in the audio buffer may be aligned, so it
may not contain a well defined number of samples.

This is consistent with the order of parameters in
av_samples_fill_arrays().

The new layout is consistent with that of the av_image_() API, and
simplifies understanding and copy operations, it also preserves
alignment information which was lost with the previous layout.

This breaks API/ABI, but since the function was never referenced in
the code (and it isn't unlikely already used by someone) then this
should not be a problem.

The new flags parameter allows to specify if the video ref to add
should overwrite the cache, if the flag is not set vsrc_buffer will
complain and abort; otherwise it will clean the already cached video
ref before to overwrite it, thus avoiding a leak.

Allow to free the buffers cached in each AVFilterLink pool.
Fix leak.

Also deprecate avcodec_get_pix_fmt_name() in its favor.

Also deprecate avcodec_get_pix_fmt_name() in its favor.

The new function accepts a slightly more intuitive order of paramters,
and returns an error code, thus allowing applications to report a
meaningful error message.

Address trac issue #33.

The new function is a wrapper around
av_vsrc_buffer_add_video_buffer_ref(), and allows to simplify the act
of pushing AVFrame data to the source buffer.

Simplify passing AVFrame data to av_vsrc_buffer_add_video_buffer_ref().

avfilter_copy_frame_props() avoids code duplication and increases
robustness.

The added files libavfilter/avcodec.[ch] are used for containing
utilities useful for gluing togheter libavfilter and libavcodec.
