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
Mans Rullgard	c682514a8f	qdm2: fix signed multiplication overflow This code relies on the result wrapping as for unsigned values, and the sign is not used. Thus an unsigned type is proper here. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Anton Khirnov	46c3c53bae	libx264: support yuv422/444 output.	13 years ago
John Stebbins	5f3fb59953	fix AC3ENC_OPT_MODE_ON/OFF The values were reversed. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	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().

Ronald S. Bultje	91f4732913	prores: implement multithreading. 60% speedup (overall decoding time) at 2 threads, and another 60% speedup at 4 threads.	13 years ago
Ronald S. Bultje	e3f530feca	prores: idct sse2/sse4 optimizations. ~3.0-3.5x as fast as original C version, 1.6x as fast overall.	13 years ago
Ronald S. Bultje	92fb52d906	prores: extract idct into its own dspcontext and merge with put_pixels.	13 years ago
Mans Rullgard	8babfc033e	h264: fix invalid shifts in init_cavlc_level_tab() The level_code expression includes a shift which is invalid in those cases where the value is not used. Moving the calculation to the branch where the result is used avoids these. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Diego Biurrun	4b7f49082f	flashsv: return more meaningful error value	13 years ago
Diego Biurrun	f9a9c8f9bc	flashsv: fix typo in av_log() message	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.

Mans Rullgard	c79d2a20ba	sipr: fix get_bits(0) calls Zero-length get_bits() is undefined, must check before calling. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	cb668476ab	motion_est: make MotionExtContext.map_generation unsigned The way this value is used, it should be an unsigned type. While the numerical value has no meaning, unsigned wraparound is relied upon. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
