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().

Anton Khirnov 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.

Anton Khirnov 428b369804 af_amix: only consider negative return codes as errors. 2012-07-06 13:51:58 +02:00
Mans Rullgard 7c29377b70 lavfi: reclassify showfiltfmts as a TESTPROG
This tool uses lavfi internal symbols not accessible in shared
libraries.  TESTPROGS are linked statically to allow them use of
library internals not normally exported.

These functions are defined conditionally so any uses need to have
preprocessor guards.

Anton Khirnov 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.

Anton Khirnov fa06623930 lavfi/audio: eliminate ff_default_filter_samples().
It currently does the following:
1) get a zeroed audio buffer
2) copy some properties (but not the data) of the input buffer to it
3) pass this buffer to the output filter
This looks useless and is indeed not used by any filters, therefore
delete it.

Make ff_null_filter_samples() (just pass the buffer to the next filter)
the new default.

Anton Khirnov e026c9b390 lavfi/audio: don't set cur_buf in ff_filter_samples().
It's redundant, since the input buffer is passed as a parameter to the
filter_samples() callback, and can lead to stale pointers remaining on
the link.
