Those functions are only useful inside filters. It is better to not
support user filters until the API is more stable.
This breaks audio filtering API and ABI in theory, but since it's
unusable right now this shouldn't be a problem.
There's no reason for it to be explicitly 32 bits. It's declared as a
plain int in all other places in Libav.
This breaks audio filtering API and ABI in theory, but since it's
unusable right now this shouldn't be a problem.
The additional parameters are just complicating the function interface.
Assume that a requested samples buffer will *always* have the format
specified in the requested link.

Remove AVFilterBufferRefAudioProps.size, and use nb_samples in its place
everywhere.
This is required as the size in the audio buffer may be aligned, so it
may not contain a well defined number of samples.
Also remove the useless planar parameter, which can be deduced from the
sample format.
This is technically an API and ABI break, but since the audio part of
lavfi is not usable now, this should not be a problem in practice.

This makes only tests actually using avconv depend on it.
The remaining tests already depend on what they need.

Just like gcc 4.6 and later on ARM, gcc 4.8 on MIPS generates
inefficient code when a known-unaligned location is used as a
memory input operand. This applies the same fix as has been
previously done to the ARM version of the code.

GCC actually handles unaligned accesses correctly in all cases
except, absurdly, 32-bit loads on mips64. The remaining asm is
thus not needed, and removing it results in better code.

libavcodec/utils.c:274: warning: passing argument 3 of ‘av_samples_fill_arrays’ discards qualifiers from pointer target type
./libavutil/samplefmt.h:151: note: expected ‘uint8_t *’ but argument is of type ‘const uint8_t *’
Unlike other variants, for YUY2 we need to use different prediction:
* on line 0 for luma we should left predict starting from the second pixel
* on line 1 we should left predict first 4 pixels for luma and 2 for chroma
* median prediction employed here is taken directly from HuffYUV
Prevents subsequent overreads when these numbers are used as indices
in arrays.
