472fb3bbfa lavfi: remove some audio-related function from public API. 
Those functions are only useful inside filters. It is better to not
support user filters until the API is more stable.

This breaks audio filtering API and ABI in theory, but since it's
unusable right now this shouldn't be a problem.

a6bdfc2a92 lavfi: change AVFilterBufferRefAudioProps.sample_rate from uint32_t to int 
There's no reason for it to be explicitly 32 bits. It's declared as a

This breaks audio filtering API and ABI in theory, but since it's
unusable right now this shouldn't be a problem.

7ef0adcc2e lavfi: simplify signature for avfilter_get_audio_buffer() and friends 
The additional parameters are just complicating the function interface.

Assume that a requested samples buffer will *always* have the format
specified in the requested link.

This breaks audio filtering API and ABI in theory, but since it's
unusable right now this shouldn't be a problem.

e727bca392 lavfi: cleanup avfilter_get_audio_buffer() and pals. 
Remove AVFilterBufferRefAudioProps.size, and use nb_samples in its place
everywhere.
This is required as the size in the audio buffer may be aligned, so it
may not contain a well defined number of samples.

Also remove the useless planar parameter, which can be deduced from the
sample format.

This is technically an API and ABI break, but since the audio part of
lavfi is not usable now, this should not be a problem in practice.

4e781c25b7 graphparser: fix the order of connecting unlabeled links. 
Right now, e.g. scale,[in]overlay would connect scale to the first
overlay input and [in] to the second, which goes against the
documentation and is unintuitive.

The bug happens because of the ordering mess in curr_inputs variable:
1) the unlabeled links from the previous filter are added to it in
correct order
2) input labels are parsed and inserted to the beginning one by one
(i.e. in reverse order)
3) curr_inputs is matched against filter inputs in reverse order

Fix the problem by always using proper ordering without trying to be
clever.

63736fe48c avfiltergraph: try to reduce format conversions in filters. 
Current code, with a filterchain such as
(input - yuv411) -> (scale - any) -> (sink - any)
will result in yuv420 being chosen for the second link, which is clearly
not right.

This commit attempts to improve in the following way:
repeat until convergence:
  loop over all filters
    find input link with exactly one format
    force this format on all output links of the same type (if possible)

737eb5976f Merge libavcore into libavutil 
It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

e8e5dde779 Make avfilter_graph_parse() not free the input graph 
Make avfilter_graph_parse() only release the internal structures
allocated during the parsing, and leave to free the graph itself to
the calling code.

This approach looks cleaner, as the graph is not allocated by the
function.

3e5bc7ff6a In the start_frame() debug log, print the reference pos value rather than the evaluated value converted to int. 
That's required because -1 is evaluated as NAN, which converted back
to int looks like a random number, this is especially annoying when
debugging sources with undefined pos (as the video4linux2 device).

    The vflip filter does not need to keep ownership of a picture reference.
    Avoid creating and releasing useless extra picture references in the
    start_frame and end_frame callbacks.

    Originally committed as revision 22596 to svn://svn.ffmpeg.org/ffmpeg/trunk

The new reference creation is required when the linesizes are used by the
previous filters in the filterchain, for example as in "pad=W:H:X:Y,vflip".
