While pshufb allows emulating bswap on XMM registers for SSSE3, more shuffling is needed for SSE2. Alignment is critical, so specific codepaths are provided for this case. For the huffyuv sequence "angels_480-huffyuvcompress.avi": C (using bswap instruction): ~ 55k cycles SSE2: ~ 40k cycles SSSE3 using unaligned loads: ~ 35k cycles SSSE3 using aligned loads: ~ 30k cycles Signed-off-by:

Current demuxer recognizes several colorspace formats that begin with 'C420' but does not yet recognize plain 'C420'. GStreamer's y4menc component generates .y4m files with a 'C420' colorspace. This new comparison is placed after the other 'C420' checks so that it doesn't interfere with them. Signed-off-by:

On x86-64, it indeed uses all 16 registers (and on x86-32, this gets clipped to 8). Not marking it properly causes callers of this function to fail randomly because of XMM register clobbering.

There was no minor bump for making avcodec_alloc_context3() public and deprecating the other two, so I'm using the first next lavc bump.

This function is video-only, so there's no point in setting more linesizes. Fixes stack corruption in avplay.

Earlier, calling avcodec_encode_audio worked fine even if time_base wasn't set. Now it crashes due to trying to scale the output pts to the codec context time base. This affects e.g. VLC. If no time_base is set for audio codecs, set it to the sample rate. CC: libav-stable@libav.org Signed-off-by:
