Michael Niedermayer	28a613b09b	h264: dont mess with chroma planes for grayscale h264. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Ronald S. Bultje	45b7bd7c53	h264: disallow constrained intra prediction modes for luma. Conversion of the luma intra prediction mode to one of the constrained ("alzheimer") ones can happen by crafting special bitstreams, causing a crash because we'll call a NULL function pointer for 16x16 block intra prediction, since constrained intra prediction functions are only implemented for chroma (8x8 blocks).

Janne Grunau	358ea75e9e	Revert "h264: skip start code search if the size of the nal unit is known" This reverts commit `87eebb3454`.	13 years ago
Janne Grunau	87eebb3454	h264: skip start code search if the size of the nal unit is known Start code emulation prevention is only required in Annex B bytestream packed NAL units. For other coding formats the size is already known. Looking for a start code prefix can result in false positives like in http://streams.videolan.org/streams/mp4/Mr_MrsSmith-h264_aac.mp4 which has a false positive in the SPS.	13 years ago

John Stebbins	53e37840bf	calculate frame_num for recovery point "keyframe" recovery points that have non-zero recovery_frame_cnt resulted in flagging incomplete frames as keyframes. This delays setting the keyframe flag till the frame has been fully constructed.	13 years ago
Michael Niedermayer	a64b028aeb	h264dec: Dont display trash before a keyframe. Fixes Ticket472 This may (or may not) cause problems with files that have no keyframes.

Diego Biurrun	806212498a	h264: move fill_decode_neighbors()/fill_decode_caches() to h264_mvpred.h This fixes a bunch of unused function warnings.	14 years ago
Diego Biurrun	028216b2c2	h264: move decode_mb_skip() from h264.h to h.264_mvpred.h This resolves a circular dependency between the headers.	14 years ago
Ronald S. Bultje	c90a2538a0	h264: move h264_mvpred.h include. Fixes the following compile error with darwin/gcc-4.2.1: In file included from libavcodec/error_resilience.c:33: libavcodec/h264.h: In function â€˜decode_mb_skipâ€™: libavcodec/h264.h:773: error: â€˜always_inlineâ€™ function could not be inlined in call to â€˜pred_pskip_motionâ€™: the function body must appear before caller libavcodec/h264.h:1334: error: called from here	14 years ago
Diego Biurrun	657ccb5ac7	Eliminate FF_COMMON_FRAME macro. FF_COMMON_FRAME holds the contents of the AVFrame structure and is also copied to struct Picture. Replace by an embedded AVFrame structure in struct Picture.	14 years ago

Reinhard Tartler	21a19b7912	doxygen: Prefer member groups over grouping into modules Before this, almost all module groups have been used for grouping functions and fields in structures semantically. This causes them to not appear properly in the file documentation and needlessly clutters up the "Modules" index. Additionally, this commit streamlines some spelling and appearances.	14 years ago
Jason Garrett-Glaser	c90b94424c	4:4:4 H.264 decoding support Note: this is 4:4:4 from the 2007 spec revision, not the previous (now deprecated) 4:4:4 mode in H.264.	14 years ago
Jason Garrett-Glaser	504811baea	Roll back 4:4:4 H.264 for now Needs some ARM/PPC asm modifications.	14 years ago

Michael Niedermayer	f0e9ee8d94	Revert "H264: Split out hl_motion and template it, this seems a bit faster" This reverts commit `a50f0bea25`. This has been implemented differently in qatar and its better they maintain it for me instead of me having to spend an average 5sec more per merge Conflicts: libavcodec/h264.c Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago

Alexander Strange	6a9c859444	H264/MPEG frame-level multi-threading. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Oskar Arvidsson	fcc0224e4f	Add support for higher QP values in h264. In high bit depth, the QP values may now be up to (51 + 6*(bit_depth-8)). Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Oskar Arvidsson	6e3ef511d7	Add the notion of pixel size in h264 related functions. In high bit depth the pixels will not be stored in uint8_t like in the normal case, but in uint16_t. The pixel size is thus 1 in normal bit depth and 2 in high bit depth. Preparatory patch for high bit depth h264 decoding support. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
