Michael Kostylev	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.

Jindrich Makovicka	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.

Anton Khirnov	30e256430e	lavc/pthread: remove obsolete checks Those were useful when avcodec_thread_init() was a public functions. It was deprecated and removed some time ago, so those checks are not needed anymore.	12 years ago

Luca Barbato	b25e49b187	mjpegdec: properly report unsupported disabled features When JPEG-LS support is disabled the decoder would feed the data to the JPEG Lossless decode_*_scan function resulting in faulty decoding. CC: libav-stable@libav.org	12 years ago

Martin Storsjö	ec7d002e55	vc1, mss2: Check for any negative return value from ff_vc1_parse_frame_header This is required if we return other error codes than explicitly -1, which so far has been the only other possible return value besides 0.

Michael Niedermayer	0313653928	vc1dec: Update destination pointers in context for fields This replaces a large number of checks for the second field by fixing the pointers when they are setup. This should also fix I/BI field pictures. Changes checksums for vc1_sa10143, the file becomes slightly closer to what the reference decoder outputs.

Diego Biurrun	f54b55058a	configure: Rename cmov processor capability to i686 The goal is to make the capapility slightly more general and have it cover the availability of the nopl instruction in addition to cmov.	12 years ago
Janne Grunau	94235f2ba2	indeo3: avoid writes without necessary alignment in copy_cell() Cells starting at a position aligned to 8 pixels but wider than 4 blocks are copied with 3 blocks per loop. This creates problems on the next loop iterations since the routine copying 2 blocks requires the same alignment on some architectures like ARM NEON.	12 years ago
