Mans Rullgard	b44522981c	avcodec: remove stray @deprecated comment Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	91038cdbd1	prores: get correct size for coded V plane if alpha is present The size check must be updated to take into account both manners in which v_data_size might be set. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	cd14e297e6	prores: do not set pixel format on codec init The pixel format is not known until the frame header is parsed. Guessing it here only causes trouble for the caller if the guess turns out to be wrong (and actually causes very wrong output by avconv/avplay). Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Ronald S. Bultje	7b6883898f	pthread: prevent updating AVCodecContext from itself in frame_thread_free Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Ronald S. Bultje	feadcd1bdc	pthread: copy coded frame dimensions in update_context_from_thread Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Ronald S. Bultje	0f0b5d6434	vp8: prevent read from uninitialized memory in decode_mvs Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Ronald S. Bultje	5653579381	vp8: force reallocation in update_thread_context after frame size change Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Ronald S. Bultje	f05c2fb6eb	vp8: fix return value if update_dimensions fails Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Justin Ruggles	a62c0f94ee	adpcmdec: calculate actual number of output samples for each decoder. This also allows for removing some of the buf_size checks and using the sample count for some of the decoding loops.	13 years ago
Justin Ruggles	439998e18b	adpcmdec: check remaining buffer size before decoding next block in the ADPCM IMA WAV decoder.	13 years ago
Justin Ruggles	ff5790c761	adpcmdec: do not terminate early in ADPCM IMA Duck DK3 decoder. There are still 2 nibbles to decode once the last byte in the packet has been read. Updated FATE reference.	13 years ago
Justin Ruggles	8140a1288f	adpcmdec: remove unneeded buf_size==0 check. This is already done by avcodec_decode_audio3()	13 years ago
Justin Ruggles	f7f7c1942b	adpcmdec: remove unneeded zeroing of *data_size	13 years ago
Mans Rullgard	d341d5fd2c	dnxhdenc: fixed signed multiplication overflow The low 32 bits of a multiplication are the same for signed and unsigned operands. Casting to unsigned before multiplying is thus equivalent while avoiding signed overflow, which is undefined by the C99 standard. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Ronald S. Bultje	05c8f119cc	proresdsp: fix function prototypes. Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Ronald S. Bultje	f78cd0c243	prores-idct: fix overflow in c code. Fix the fate ref for prores-422_proxy by reverting the changes to it in commit `f492df0927` Signed-off-by: Janne Grunau <janne-libav@jannau.net>	13 years ago
Janne Grunau	19ec283f49	prores: add missing feature warning for alpha	13 years ago
Dustin Brody	582f231142	lavc: add a flag-based error_recognition field to AVCodecContext and deprecate non-flag-based ER field Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Dustin Brody	ac90a71459	lavc: rename deprecation symbol FF_API_VERY_AGGRESSIVE to FF_API_ER Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Justin Ruggles	617a51f9b7	shorten: remove the flush function. The shorten decoder does not support seeking.	13 years ago
Justin Ruggles	c6ac30c84b	truespeech: use sizeof() instead of hardcoded sizes	13 years ago
Justin Ruggles	6d55506c8b	truespeech: remove unneeded variable, 'consumed' increment the 'buf' pointer instead, and consume the whole packet.	13 years ago
Justin Ruggles	b84048935e	truespeech: simplify truespeech_read_frame() by using get_bits()	13 years ago
Justin Ruggles	5e5ce70f19	truespeech: decode directly to output buffer instead of a temp buffer	13 years ago
Justin Ruggles	3e7a176759	truespeech: check to make sure channels == 1	13 years ago
Justin Ruggles	a8f8db2636	truespeech: check for large enough output buffer rather than truncating output	13 years ago
Justin Ruggles	595cf1a1aa	truespeech: remove unneeded zero-size packet check. This is already checked in avcodec_decode_audio3()	13 years ago
Justin Ruggles	82be06bbb3	mlpdec: return meaningful error codes instead of -1	13 years ago
Justin Ruggles	e1b8d88d52	mlpdec: remove unnecessary wrapper function	13 years ago
Justin Ruggles	37b67f1bff	mlpdec: only calculate output size once	13 years ago
Justin Ruggles	caa845851d	mlpdec: validate that the reported channel count matches the actual output channel count	13 years ago
Mans Rullgard	b45eb9d619	pcm: reduce pointer type casting Making 'samples' a pointer to uint8_t simplifies the DECODE macro and reduces the amount of type casting overall. This also fixes some signed overflows on left shift. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	f59bb3d8f3	mathops: remove undefined behaviour from sign_extend() This function intentionally overflows the signed range on the left shift. Using this type-punning avoids errors from the overflow checker without disabling this test globally. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Kostya Shishkov	42feaf4070	vc1: explicitly zero interlaced mode coding variables for progressive mode Both v->fcm and v->field_mode are used in common code, now they won't be reset for progressive frame after interlaced one causing writing past the frame end for example. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Jean First	47a1d794db	tiffenc: initialize forgotten avctx.	13 years ago
Kostya Shishkov	50f9721904	vc1: more prettyprinting cosmetics Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Kostya Shishkov	94e725ca2b	vc1: prettyprint some tables Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago

Anton Khirnov	145f741e11	AVOptions: rename FF_OPT_TYPE_* => AV_OPT_TYPE_*	13 years ago
Anton Khirnov	641c7afe3c	AVOptions: add new API for enumerating children. This will allow the caller to enumerate child contexts in a generic way and since the API is recursive, it also allows for deeper nesting (e.g. AVFormatContext->AVIOContext->URLContext) This will also allow the new setting/reading API to transparently apply to children contexts.	13 years ago
Janne Grunau	1bca8f4bc5	rv34: move inverse transform functions to DSP context	13 years ago
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(). Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
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
