Janne Grunau	ea49f60523	h264: skip chroma edges at the picture boundary while deblocking 4:4:4 This handles macroblock edges for the chroma components in the same way as for the luma compoment for 4:4:4 streams. The Spec explicitly states that the deblocking filter is not applied to edges at the boundary of the picture. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	11 years ago
Reimar Döffinger	76421982d0	lossless_videodsp.asm: fix compilation. Fixes these errors with nasm: libavcodec/x86/lossless_videodsp.asm:86: error: invalid combination of opcode and operands libavcodec/x86/lossless_videodsp.asm:88: error: invalid combination of opcode and operands I don't know whether movd or movq was meant, but either way maskq vs. maskd must match the mov size.

Anton Khirnov	e0ab5078a7	lavc: do not force the emu edge flag The default get_buffer2() implementation (and possibly some user ones) does not allocate edges when this flag is set, which may expose bugs in some decoders. Until the 10 release is out, it is safer to remove this part.	11 years ago

Luca Barbato	e22ebd04bc	hevc: Bound check cu_qp_delta The T-REC-H.265-2013044 page 91 states it has to be in the range [-(26 + s->sps->qp_bd_offset / 2), (25 + s->sps->qp_bd_offset / 2)].	11 years ago
Luca Barbato	0d999333f9	hevc: Bound check slice_qp The T-REC-H.265-2013044 page 79 states it has to be in the range [-s->sps->qp_bd_offset, 51]. Sample-Id: 00001386-google Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	11 years ago

Guillaume Martres	faf03ecba0	hevc: Remove useless clip The src buffer should only contain values in the interval [0, (1 << BIT_DEPTH) - 1]. Since shift = (BIT_DEPTH - 5), src[x] >> shift must be in the interval [0, 31], so no clip is needed. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Guillaume Martres	a246d06fe0	hevc: clip pixels when transquant bypass is used The reconstructed picture should always be clipped (see section 8.6.5), previously we did not clip coding units where cu_transquant_bypass_flag == 1.

Michael Niedermayer	dd2d0039b6	vc1: Always reset numref when parsing a new frame header. Fixes an issue where the B-frame coding mode switches from interlaced fields to interlaced frames, causing incorrect decisions in the motion compensation code and resulting in visual artifacts.
