77cc958f60 lavfi: add const to the AVFilter parameter of avfilter_graph_create_filter() 
This function should never modify the filter.

096696ef0d avfiltergraph: simplify inserting conversion filters. 
There is now no need to explicitly pass 0:0 as width/height to scale,
those are the defaults.

c2c9801bc9 lavfi: deprecate avfilter_graph_add_filter(). 
Since this function adds a standalone filter to a filter graph and we do
not support creating such filters, there is no reason for this function
to exist.

bc1a985ba0 lavfi: replace avfilter_open() with avfilter_graph_alloc_filter(). 
Since we do not support "standalone" filters not attached to an
AVFilterGraph, we should not have a public function to create such
filters. In addition that function is horribly named, the action it does
cannot be possibly described as "opening" a filter.

38f0c0781a lavfi: merge avfiltergraph.h into avfilter.h 
We do not support using filters without AVFilterGraph in practice
anyway, so there is no point in pretending we do.

e3496e5dbe avfiltergraph: silence an uninitialized variable warning 
The warning is:
libavfilter/avfiltergraph.c: In function ‘avfilter_graph_config’:
libavfilter/avfiltergraph.c:528:9: warning: ‘best_idx’ may be used uninitialized in this function [-Wuninitialized]
libavfilter/avfiltergraph.c:479:13: note: ‘best_idx’ was declared here

Initialize it to an invalid value and add an assert that it's properly
set later.

743f07062a lavfi: better channel layout negotiation 
Allow substitution of channel pairs in the input for nearby channel pairs in
the output in order to get a closer match. Also weigh LFE channel mismatch
differently to favor matching the same layout without LFE over one less
channel with LFE.

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)

4fcbb2af33 Prefix with "ff_" the functions: 
ff_avfilter_graph_check_validity()
ff_avfilter_graph_config_links()
ff_avfilter_graph_config_formats()

and move their declaration to internal.h. These functions are never
used in application code, so it is better to consider them internal
functions, this can be changed later if necessary. Simplify API.

24de0edbd5 Rename avfilter_destroy() as avfilter_free().

sounds less evil.
