7cdd737ba8 lavfi: mark filters with dynamic number of inputs or outputs with special flags 
This will be useful in avtools in the following commits.
Any other caller might also want to know this information.

7e350379f8 lavfi: switch to AVFrame. 
Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it
and use AVFrame instead.

565e4993c6 lavfi: merge start_frame/draw_slice/end_frame 
Any alleged performance benefits gained from the split are purely
mythological and do not justify added code complexity.

a903f8f087 Include libavutil/channel_layout.h instead of libavutil/audioconvert.h 
Also reorder some other #include when applicable.

568c70e79e lavfi: convert input/ouput list compound literals to named objects 
A number of compilers, for example those from TI and IBM, choke on
these initialisers.  The current style is also quite ugly.

cd99146253 lavfi: add error handling to filter_samples(). 2012-07-09 08:25:19 +02:00
Anton Khirnov
b7558ac293 af_amix: avoid spurious EAGAIN. 
Input on/off state can change in request_samples(), which can result in
a state where only the first input is active. get_available_samples()
will then return 0, and request_frame() will fail with EAGAIN even
though there is data on the single active input.

Take this into account and check the number of active inputs again after
calling request_samples().

54bf88e65f af_amix: return AVERROR(EAGAIN) when request_frame didn't produce output. 
0 should only be returned when there was at least one output frame.

a5e8c41c28 lavfi: remove 'opaque' parameter from AVFilter.init() 
It is not used in any filters currently and is inherently evil. If
passing binary data to filters is required in the future, it should be
done with some AVOptions-based system.
