Guillaume Martres	50866c8d95	vp9: fix bugs in updating coef probabilities with parallelmode=1 - The memcpy was completely wrong because s->prob_ctx[s->framectxid].coef is a [4][2][2][6][6][3] array, whereas s->prob.coef is a [4][2][2][6][6][11] array. - The additional check was committed to ffmpeg by Ronald S. Bultje. Signed-off-by: Anton Khirnov <anton@khirnov.net>	11 years ago

Michael Niedermayer	a26e9c1040	avcodec/mjpegenc: Use av_frame_clone() instead of av_frame_ref() This avoids the need for double error checking Fixes CID1163843 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago

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

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

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.
