Michael Niedermayer	3aa661ec56	h264: improve parsing of broken AVC SPS Parsing the entire NAL as SPS fixes decoding of some AVC bitstreams with broken escaping. Since the size of the NAL unit is known and checked against the buffer end we can parse it entirely without buffer overreads.

Michael Niedermayer	2ed7e353bd	h264: Workaround invalid flag combinations of 8x8 inference. Fixes Ticket555 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Mans Rullgard	fdba370f8a	h264: fix HRD parameters parsing The bit_rate_value_minus1 and cpb_size_value_minus1 elements allow a wider range than get_ue_golomb() supports. This adds a get_ue_golomb_long() function supporting up to 31 leading zeros, which is the maximum for these syntax elements, and uses it in decode_hrd_parameters(). Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	be1242a3f2	h264: fix detection of optional trailing PPS elements The PPS may contain a few trailing elements whose presence is only signalled by data remaining after the the mandatory part has been parsed. The current code fails to take into account the rbsp_trailing_bits() when deciding whether to parse these optional elements. Assuming no unnecessary padding bytes are passed to this function, the optional elements are present if either more than 8 extra bits remain or the remaining bits do not form a valid rbsp_trailing_bits() after the mandatory PPS elements have been parsed.

Laurent Aimar	bcf881a685	h264: fix the check for invalid SPS:num_ref_frames. This patch set the limit to 16. For information, thoses previous commits: `41f7e2d11d` `5cbb0e70a0` assumed it was either 30 or 32. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Carl Eugen Hoyos	66624cbb80	Disable cropping for the brainfart case. This fixes ticket #348 for the few users who have a playback application that supports Sisvel 3D. The other 99% have to wait until FFmpeg supports arbitrary cropping.	13 years ago

Reinhard Tartler	7ffe76e540	Merge libavcore into libavutil Done to keep ABI compatible. Otherwise this is just silly	14 years ago
Reinhard Tartler	737eb5976f	Merge libavcore into libavutil It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.
