72dee5f40b wavpack: don't set sample format in init. 
We don't know whether it will be float until we look at the data.

35596bd4f4 wavpack: remove a useless parameter from wavpack_decode_block().

1d177200ce wavpack: remove a useless check. 
Number of samples in the first block is checked to be strictly positive
earlier in wavpack_decode_frame() and number of samples in all the other
blocks is checked to be equal to the first one.

474fb0c9d9 wavpack: return 0 instead of samples count from decoding functions 
The caller never cares about the number of decoded samples, so this only

5f30c6c8ed Revert "smackaud: clip output samples" 
Smacker audio uses overflows instead of clipping.

This reverts commit 375ca0aca81be2951d9ba4731196e70e490d3cdf.

2a6eaeaa85 Move get_logical_cpus() from lavc/pthread to lavu/cpu. 
It will be useful in lavfi, and could conceivably be useful to the user

3eae9b030c mpegvideo: unref buffers in ff_mpeg_unref_picture on frame size changes 
ff_mpeg_unref_picture clears the flag indicating that the frame needs to
be reallocated after a frame size change. Since we have now reference
counted buffers we can unref the buffers immediately.

4b79668154 mpegvideo: unref old current_picture before allocating a new one 
Allows decoding with only three frame buffers with frame reference
counting. Fixes VAAPI based decoding in vlc which uses only three
frame buffers for the mpegvideo-based codecs.

db347280eb vorbis: fallback to normal division instead of crashing 
The use of ff_inverse speeds up slightly arches + compilers that
do not provide a division faster than the whole machinery, such
as ppc32 + gcc4.7, but has operational limits.

Drop the always-enable assert and provide a fallback.

2768f7e4fe sparc: VIS mnemonics 
Currently, if VIS is enabled by configure, it will also be enabled at
run-time regardless of its support in the hardware. Thus, masking VIS
usage as it is done in vis.h by constructing binary instructions is
pointless. Using normal VIS mnemonics in inline assembly allows to take
advantage of automatic register allocation, gets rid of register
variables, which are unsupported by suncc for SPARC, and improves code
readability.

259af1b923 mpegvideo: allocate sufficiently large scratch buffer for interlaced vid 
MPV_decode_mb_internal needs 3 * 16 * linesize bytes of scratch buffer

For interlaced content, linesize is multiplied by two after the allocation
of the scratch buffer, and the dest_cr pointer ends past the buffer.

This patch makes ff_mpv_frame_size_alloc allocate a total of
(aligned line_size) * 2 * 16 * 3 bytes, which suffices even for the
interlaced case.
