3d01996b24 fftools/ffmpeg_filter: change processing order in fg_finalise_bindings() 
First bind all inputs in all filtergraphs, only then check that all
outputs are bound.

Needed by the following commit.

a4c940c86a fftools/ffmpeg_filter: move most of -apad logic to the muxer 
The decision whether -apad actually does anything is made based on muxer
properties, and so more properly belongs there. Filtering code only

2ee9362419 fftools/ffmpeg: remove unncessary casts for *_thread() return values 
These functions used to be passed directly to pthread_create(), which
required them to return void*. This is no longer the case, so they can

f5d03b972c fftools/ffmpeg: simplify propagating fallback parameters from decoders to filters 
Current callstack looks like this:
* ifilter_bind_ist() (filter) calls ist_filter_add() (demuxer);
* ist_filter_add() opens the decoder, and then calls
  dec_add_filter() (decoder);
* dec_add_filter() calls ifilter_parameters_from_dec() (i.e. back into
  the filtering code) in order to give post-avcodec_open2() parameters
  to the filter.

This is unnecessarily complicated. Pass the parameters as follows
instead:
* dec_init() (which opens the decoder) returns post-avcodec_open2()
  parameters to its caller (i.e. the demuxer) in a parameter-only
  AVFrame
* the demuxer passes these parameters to the filter in
  InputFilterOptions, together with other filter options

7b51523f12 fftools/ffmpeg_opt: merge init_complex_filters() and check_filter_outputs() 
The first of these binds inputs of complex filtergraphs to demuxer
streams (with a misleading comment claiming it *creates* complex
filtergraphs).

The second ensures that all filtergraph outputs are connected to an
encoder.

Merge them into a single function, which simplifies the ffmpeg_filter
API, is shorter, and will also be useful in following commits.

Also, rename misleadingly-named init_input_filter() to
fg_complex_bind_input().

c4de5778bc fftools/ffmpeg_dec: factor opening the decoder out of dec_open() 
Rename dec_open to dec_init(), as it is more descriptive of its new
purpose.

Will be useful in following commits, which will add a new path for
opening decoders.

8f592eb35f fftools/ffmpeg_filter: compute input trim start/end in demuxer 
The computation is based on demuxer properties, so that is the more
appropriate place for it. Filter code just receives the desired

44620ade25 fftools/ffmpeg_mux_init: Fix attachment_filename use-after-free 
The filename is freed with the OptionsContext and therefore
there will be a use-after-free when reporting the filename
in print_stream_maps(). So create a copy of the string.

This is a regression since 8aed3911fc.
fate-lavf-mkv_attachment exhibits it (and reports a random nonsense
filename here), but this does not make the test fail (not even with
valgrind; only with ASAN, as it aborts on use-after-free).

0d00e2e2f7 fftools/ffmpeg_dec: eliminate all remaining InputStream uses 
Previously, the demuxer would register decoder with the scheduler, using
InputStream as opaque, and pass the scheduling index to the decoder.

Now the registration is done by the decoder itself, using DecoderPriv as
opaque, and the scheduling index is returned to demuxer from dec_open().

decoder_thread() then no longer needs to be accessed from outside of
ffmpeg_dec and can be made static.
