Michael Niedermayer	3af2de76ac	h264: set unused ref_counts to 0 as a precautionary meassure. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	c9c7a776db	h264: try reading SPS with wrong escaping, it sometimes works better Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	dc9ce40069	h264: More correct ref_count check in decode_slice_header() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
Laurent Aimar	d1186ff72d	h264: check for out of bounds reads in ff_h264_decode_extradata(). Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago

Diego Biurrun	95a06eb4d5	Fix assert() calls that need updates after FF_COMMON_FRAME macro elimination. This fixes build failures with -DDEBUG in CPPFLAGS.	13 years ago
Michael Niedermayer	4832ed4c62	h264: do not increase recovery frame which would lead to endless moving away of the recovery point. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	a8a9844a3c	h264: reset recovery frame on seeks. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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. Plese open a bugreport or mail me if you have a file for which this fails. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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.	13 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
