2012-02-10h264: disallow constrained intra prediction modes for luma.Ronald S. Bultje
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). Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
2012-01-31h264: Split h264-test off into a separate file - golomb-test.c.Diego Biurrun
The new name is more appropriate as only golomb functions are tested.
2012-01-31h264-test: cleanup: drop timer invocations, commented out code and other cruftDiego Biurrun
2012-01-31h264-test: Remove unused DSP and AVCodec contexts and related init calls.Diego Biurrun
This also avoids a segfault on startup.
2012-01-13cabac: split cabac.h into declarations and function definitionsDiego Biurrun
This fixes standalone compilation of some decoders with --disable-optimizations. cabac.h defines some inline functions that use symbols from cabac.c. Without optimizations these inline functions are not eliminated and linking fails with references to non-existing symbols. Splitting the inline functions off into their own header and only #including it in the places where the inline functions are used allows #including cabac.h from anywhere without ill effects.
2012-01-08h264-test: Initialize AVCodecContext.av_class.Diego Biurrun
This fixes a segfault on startup. Also remove a commented-out and completely unused variable.
2012-01-06h264: Only use symbols from the SVQ3 decoder under proper conditionals.Diego Biurrun
Fixes --disable-everything --enable-decoder=h264 --disable-optimizations.
2012-01-04h264: return index in buffer on end-of-sequence.Ronald S. Bultje
Fixes hangs if the last packet contains an end-of-sequence NAL unit, bug 158.
2012-01-04Merge some declarations and initializations.Diego Biurrun
This fixes compilation failures related to START_TIMER/STOP_TIMER macros and -Werror=declaration-after-statement. START_TIMER declares variables and thus may not be placed after statements outside of a new block.
2012-01-02mpegenc: use avctx->slices as number of slicesJanne Grunau
Adds a new member to MpegEncContext to hold the number of used slice contexts. Fixes segfaults with '-threads 17 -thread_type slice' and fate-vsynth{1,2}-mpeg{2,4}thread{,_ilace} with --disable-pthreads.
2011-12-23h264: Fix a possible overread in decode_nal_units()Alexander Strange
Signed-off-by: Anton Khirnov <anton@khirnov.net>
2011-12-20h264: clear trailing bits in partially parsed NAL unitsJanne Grunau
Trailing bits are likely to be non-zero if the NAL unit is truncated. Clearing the bits make overreads of the bitstream less likely in this case. Fixes playback of http://streams.videolan.org/streams/mp4/Mr_MrsSmith-h264_aac.mp4 which has a forbidden byte sequence of 0x00 0x00 0x00 in it SPS.
2011-12-19Revert "h264: skip start code search if the size of the nal unit is known"Janne Grunau
This reverts commit 87eebb3454ff0cd6af6ebf9e1d31bdfd1c3b601b.
2011-12-19h264: skip start code search if the size of the nal unit is knownJanne Grunau
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.
2011-12-16h264: don't drop B-frames after next keyframe on POC reset.Ronald S. Bultje
The keyframe after a POC reset may not be the first to be returned to the user. Therefore, don't reset the expected next POC once we return a keyframe to the user, but once we know that the next frame in the return-queue is a keyframe.

2011-12-03h264: fix frame reordering code.Ronald S. Bultje
Fixes fate-h264-conformance-{mr2_tandberg_e,mr3_tandberg_b} without requiring -strict 1.
2011-12-02h264: cap max has_b_frames at MAX_DELAYED_PIC_COUNT - 1.Ronald S. Bultje
This prevents frame allocation overflows, and fixed fate-h264-conformance-mr3_tandberg_b with 2 threads.

2011-11-19avcodec: move some AVCodecContext fields to an internal struct.Justin Ruggles
A new field, AVCodecContext.internal is used to hold a new struct AVCodecInternal, which has private fields that are not codec-specific and are used by general libavcodec functions. Moved internal_buffer, internal_buffer_count, and is_copy.

2011-10-21h264: mark some MC functions with av_always_inline instead of inline.Ronald S. Bultje
This actually causes them to be inlined, leading to a significant speedup (1-1.5% in my measurements).
