Mans Rullgard	318efbfc10	h264: change unsupported bit depth message to error level Unsupported bit depth is certainly an error the user will want to know about. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Laurent Aimar	4c7a232fc8	h264: reset h->ref_count in case of errors in ff_h264_decode_ref_pic_list_reordering() Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago

Michael Niedermayer	74f77eb048	H264: set colorspace and full range to values indicating unspecified by default Code based on ffdshow Author unknown Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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	5a6e7771ed	h264: dont set key_frame when the frame is not a real keyframe. Fixes Ticket514 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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

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

Luca Barbato	22141917a9	Revert "h264: Properly set coded_{width, height} when parsing H.264." This reverts commit `b47904d158`. coded_{width, height} overwrites width and height in avcodec_open and it currently just report the non-lowres size.	14 years ago

Mans Rullgard	5cc2600964	dsputil: create 16/32-bit dctcoef versions of some functions High bitdepth H.264 needs 32-bit transform coefficients, whereas dnxhd does not. This creates a conflict with the templated functions operating on DCTELEM data. This patch adds a field allowing the caller to choose the element size in dsputil_init() and adds the required functions. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
