This is more consistent with naming in the rest of Libav.

This will allow making AVFilterPad opaque for the calling apps, since
those are the only two fields that can be useful to the users.

These functions are modeled after the corresponding utilities in
libavutil/timestamp.h.

The function was introduced in 4d6a8a2bdb and is not used anymore
outside avfilter.c.

This avoids to pollute the public API with an apparently unnecessary
function. The function was introduced a few days ago, so removing it from
the public API should do no much harm.

The function is modelled after av_default_item_name(), and will print the
name of the instance filter if defined, otherwise the name of the filter.

This allows to show the instance name in the log, which is useful when
debugging complex filter graphs.

Introduce a new function to set binary data through AVOption,
avoiding having to convert the binary data to a string inbetween.

Move AVPALETTE_SIZE and AVPALETTE_COUNT definition from
libavcodec/avcodec.h to libavutil/pixfmt.h.

The definition is more useful in libavutil, where it can be shared for
example by libavfilter and libswscale.

Guesses the sample aspect ratio of a frame, based on both the stream and the
frame aspect ratio.

Since the frame aspect ratio is set by the codec but the stream aspect ratio
is set by the demuxer, these two may not be equal. This function tries to
return the value that you should use if you would like to display the frame.

Basic logic is to use the stream aspect ratio if it is set to something sane
otherwise use the frame aspect ratio. This way a container setting, which is
usually easy to modify can override the coded value in the frames.

Rationale is the same as for video width/height etc.

Appears this was forgotten

This moves the cpu flag parsing code from avconv to avutil so
it can be accessed elsewhere.

This is a new library for audio sample format, channel layout, and sample rate
conversion.

The functions operate on the sample level rather than the byte level and work
with all audio sample formats.

This is required for letting applications to create and destroy

The header is part of the public API, in particular is used by
doc/examples/filtering_audio.c.

Also, use the new function in the AC-3 encoder.

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.
