23ffc4c70d doc/examples/muxing: Fixes frame initialization.
Fixes use of the example with encoders which use tha AVFrame w/h/pix_fmt fields
FFV1 is one of these codecs

We cannot easily workaround the not set fields in common code because the API
has AVFrame constant for the encoders.
Alternatives would be to fix the API or to duplicate the struct and fill in
missing fields. Or as is to require all user apps to set this correctly and
maybe simplify for that case

43f116d162 examples/demuxing_decoding: return error when no codec found
The open_codec_context function, when it fails to find a codec, now
return AVERROR(EINVAL) to signal an error.

Before it would return the stream index, which was always >= 0, and
continue as if a codec was found. This change make it fail faster,
instead of repeated failed tries to decode frames with no codec.

There is no reason why this should copy the audio data in a very

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.

Add function avfilter_graph_parse_ptr() and favor it in place of

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.

13bbc464ed examples/muxing: set codec in the codec context
Make add_{audio,video}_stream return the found codec, and pass it to
avcodec_open2() through open_{audio,video} functions.

Fix failure:
No codec provided to avcodec_open2().
could not open codec

This is also consistent with the use of the avcodec_open2() API in the
codebase.
