9f31c1608c examples: demuxing: simplify audio output 
There is no reason why this should copy the audio data in a very
complicated way. Also, strictly write the first plane, instead of
writing the whole buffer. This is more helpful in context of the
example. This way a user can clearly confirm that it works by playing
the written data as raw audio.

06b269dacb examples: demuxing: do partial audio packet decoding 
This assumes one audio packet is decoded one time. This is not true:
packets can be partially decoded. Then you have to "adjust" the packet
and pass the undecoded part of the packet to the decode function again.

838bd73139 lavfi: create Libav-API compatibility layer for avfilter_graph_parse() at the next bump 
Add function avfilter_graph_parse_ptr() and favor it in place of
avfilter_graph_parse(), which will be restored with the old/Libav
signature at the next bump.

If HAVE_INCOMPATIBLE_LIBAV_API is enabled it will use the
Libav-compatible signature for avfilter_graph_parse().

At the next major bump the current implementation of
avfilter_graph_parse() should be dropped in favor of the Libav/old
implementation.

Should address trac ticket #2672.

9b211c43dc examples/muxing: fix memory leak. 
Do not re-call avcodec_get_context_defaults3(), it is already
called by avformat_new_stream() and it leaks the codec
priv_data that was already allocated.

Use avformat_free_context() instead of freeing (not)
everything manually.

Fix trac ticket #2322.

dcc73aaaa9 doc/examples: do not allocate AVFrame directly. 
The size of the AVFrame structure is not part of the ABI;
it can grow with later versions. Therefore, applications
are not supposed to allocate AVFrame directly, they are
supposed to use avcodec_alloc_frame() instead.

bcf93f78a5 examples/decoding_encoding: replace "picture" with "frame" in encode_example()

1d0048cfe3 examples/muxing: rename img_convert_ctx to sws_ctx 
The new name is more consistent with the codebase, and more
self-consistent with the libswscale API.

bdd9bfbbab examples/muxing: prefer AVPicture to AVFrame, when feasible 
Favor the use of plain AVPicture over AVFrame, especially when the use of
AVFrame is not required like in the case of tmp_picture.

Also adopt more straightforward names, to avoid frame/picture confusion.

e53becc70f examples/Makefile: give priority to pkg-config flags 
In case CFLAGS/LDLIBS are already defined and conflicting with the
pkg-config flags, give priority to the latter since they are used to
detect compilation flags.

This should fix for example the case where there are many different
instances of a library, CFLAGS=-I/foo/include and pkg-config cflags say
-I/bar/include.

74419fcf45 examples: add scaling_video example 
This example should be useful to show the basic functionality of the

More advanced features (scaling options etc., colorspace tweaking) may be
added later.
