Michael Niedermayer	545ec935a4	h264: Use mismatching frame numbers in fields to synchronize the first/second field state independant of them being reference or not. Fixes Ticket354 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Joakim Plate	29a29226bb	Set avctx->coded_width/height to uncropped h264 sizes avctx->width/height remain right/bottom cropped as previous behaviour. Hardware decoders need to know the uncropped data to allocate surfaces of correct height. Some hardware is picky and fails to decoder properly if a surface larger than needed is used during decode, so just aligning up is not enough.

Ronald S. Bultje	27209bb108	h264: mark some MC functions with av_always_inline instead of inline. This actually causes them to be inlined, leading to a significant speedup (1-1.5% in my measurements).	13 years ago

Michael Niedermayer	14c21c1ff5	H264: Only wait before triggering ff_thread_setup_complete() until the next slice that contains a start-of-field/frame macroblock This allows concurrent decoding of the last field/frame, rather than only the last slice, of data packets with multiple NAL units packed together. This will fix the slowdown reported in e.g. bug 52. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago

Michael Niedermayer	eaa21b6870	H264: hotfix for speedloss on frame threading and h264 files with slices. This fix is not ideal as it still limits the multithreading on field pictures to the 2nd field only. Ill try to fix it properly to allow both fields to decode concurrently but this needs more work. This bug exists since and was caused by: commit `ea6331f8bb` Author: Ronald S. Bultje <rsbultje@gmail.com> Date: Mon Jun 20 10:24:33 2011 -0400 h264-mt: fix deadlock in packets with multiple slices (e.g. MP4).	13 years ago

Michael Niedermayer	f85c9b7771	h264dec: fix decoding problems introduced with `baad01d8b4`. This affected cases where extradata was not set. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Alexander Strasser	baad01d8b4	h264: improve checks before calling ff_h264_decode_extradata The ff_h264_decode_extradata routine now checks for the buffer size and pointer internally. This makes it possible to remove the external checks in ff_h264_decode_init. In decode_frame there was a size check missing because the buffer gets tested prior to the invocation of ff_h264_decode_extradata(). Signed-off-by: Alexander Strasser <eclipse7@gmx.net>	13 years ago
Alexander Strasser	715f259bf9	h264: ff_h264_decode_extradata: check buffer args The buffer size and pointer were not checked prior to testing the first byte of the buffer. These were sometimes checked before calling, but it is better to add it inside the function as it takes buf and size arguments. Signed-off-by: Alexander Strasser <eclipse7@gmx.net>	13 years ago
