Ronald S. Bultje	24947d4988	vorbis: fix overflows in floor1[] vector and inverse db table index.	13 years ago
Ronald S. Bultje	7e4d9d5d45	win64: add a XMM clobber test configure option. This will be useful to test more aggressively for failures to mark XMM registers as clobbered in Win64 builds, and prevent regressions thereof. Based on a patch by Ramiro Polla <ramiro.polla@gmail.com>	13 years ago
Mans Rullgard	cd2f98f365	ARM: ac3: fix ac3_bit_alloc_calc_bap_armv6 This function was broken when the start bin was not at the start of a band. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Piotr Bandurski	3f57bde1f2	frwu: lowercase the FRWU codec name This is more consistent with all the other codec names. Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago
Paul B Mahol	38c6bbc118	ra144enc: drop pointless "encoder" from .long_name Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Justin Ruggles	c3a06615bd	bethsoftvideo: fix palette reading. Return the correct number of consumed bytes and set *data_size = 0. Returned size is 1 too small, leading to that 1 byte being read as the next frame, which results in an extra blank frame at the beginning of the stream.	13 years ago
Justin Ruggles	83ce51cc7d	mpc7: use av_fast_padded_malloc() Avoids doing malloc/free for each frame. Also fixes valgrind errors due to use of uninitialized padding bytes. Based on a patch by Reimar Döffinger <Reimar.Doeffinger@gmx.de>	13 years ago
Justin Ruggles	b5b825c381	mpc7: simplify handling of packet sizes that are not a multiple of 4 bytes	13 years ago
Justin Ruggles	236a550c3f	Fix a typo in the x86 asm version of ff_vector_clip_int32() Specifies the correct number of xmm registers used so that they can be saved and restored on Win64 if necessary.	13 years ago
Justin Ruggles	3c432631e9	pcmenc: Do not set avpkt->size. It is already the correct size as set by ff_alloc_packet().	13 years ago
Justin Ruggles	1a670973a7	ff_alloc_packet: modify the size of the packet to match the requested size This will simplify encoders which use this function to request the exact packet size rather than the maximum size.	13 years ago
Paul B Mahol	5ff88020ac	frwu: Employ more meaningful return values. Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Reimar Döffinger	f54ae2f8e7	fraps: Use av_fast_padded_malloc() instead of av_realloc() Ensures alignment and avoids using uninitialized data. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Reimar Döffinger	0880503fbb	mjpegdec: use av_fast_padded_malloc() also check for allocation failure Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Reimar Döffinger	2f4b9021a1	eatqi: use av_fast_padded_malloc() Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Reimar Döffinger	00db4d4ad5	asv1: use av_fast_padded_malloc() Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Janne Grunau	316fc7443b	avcodec: Add av_fast_padded_malloc(). Wrapper around av_fast_malloc() that keeps FF_INPUT_BUFFER_PADDING_SIZE zero-padded bytes at the end of the used buffer. Based on a patch by Reimar Döffinger <Reimar.Doeffinger@gmx.de>.	13 years ago
Diego Biurrun	3b637dca72	avcodec.h: Remove some disabled cruft.	13 years ago
Paul B Mahol	8ca8e4a846	zmbv: Employ more meaningful return values. Also use av_log_ask_for_sample() where it makes sense. Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago

Janne Grunau	cb0b284381	zmbv: check av_realloc() return values and avoid memleaks on ENOMEM	13 years ago
Paul B Mahol	d4eeadcbbf	truespeech: align buffer DSPContext.bswap_buf() requires aligned output Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Mans Rullgard	034b03e7a0	ac3: Do not read past the end of ff_ac3_band_start_tab. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Alex Converse <alex.converse@gmail.com>	13 years ago
Janne Grunau	e67e3a3f4a	fate-golomb: extend golomb-test to get_ue_golomb_long() get_ue_golomb_long() is only tested for values up to 2^15 - 2 since we can not write larger values. Silence the test on success and return a non-zero value on error. Use an heap scratch buffer instead of large stack buffer. Remove unneeded includes.	13 years ago
Diego Biurrun	9e3a2736bd	golomb-test: K&R formatting cosmetics	13 years ago
Diego Biurrun	631f96f959	h264: Split h264-test off into a separate file - golomb-test.c. The new name is more appropriate as only golomb functions are tested.	13 years ago
Diego Biurrun	4ff46af039	h264-test: cleanup: drop timer invocations, commented out code and other cruft	13 years ago
Diego Biurrun	3856a2aaa6	h264-test: Remove unused DSP and AVCodec contexts and related init calls. This also avoids a segfault on startup.	13 years ago
Diego Biurrun	b010178e84	adpcm: Add missing stdint.h #include to fix standalone header compilation.	13 years ago
Anton Khirnov	bc90199848	lavc: set AVCodecContext.codec in avcodec_get_context_defaults3(). This way, if the AVCodecContext is allocated for a specific codec, the caller doesn't need to store this codec separately and then pass it again to avcodec_open2(). It also allows to set codec private options using av_opt_set_* before opening the codec.	13 years ago
Anton Khirnov	0e72ad95f9	lavc: make avcodec_close() work properly on unopened codecs. I.e. free the priv_data and other stuff allocated in avcodec_alloc_context3() and not segfault.	13 years ago
Anton Khirnov	af08d9aeea	lavc: add avcodec_is_open(). It allows to check whether an AVCodecContext is open in a documented way. Right now the undocumented way this check is done in lavf/lavc is by checking whether AVCodecContext.codec is NULL. However it's desirable to be able to set AVCodecContext.codec before avcodec_open2().	13 years ago
Anton Khirnov	afa4069e3b	lavc/lavf: remove unnecessary symbols from the symbol version script.	13 years ago
Anton Khirnov	f5f49a66a2	lavc: reorder AVCodec fields. Put all private fields at the end and mark them as such so they can be easily changed/removed. This breaks ABI.	13 years ago
Alex Converse	f372ce119b	mp3dec: Fix a heap-buffer-overflow In some cases, what is left to read from ptr is smaller than EXTRABYTES. Based on a patch by Thierry Foucu <tfoucu@gmail.com>. Signed-off-by: Alex Converse <alex.converse@gmail.com>	13 years ago
Justin Ruggles	a3a0691bde	adpcmenc: remove some unneeded casts	13 years ago
Justin Ruggles	149f2058a4	adpcmenc: use int16_t and uint8_t instead of short and unsigned char.	13 years ago
Justin Ruggles	dd88ae831a	adpcmenc: fix adpcm_ms extradata allocation Add FF_INPUT_BUFFER_PADDING_SIZE. If allocation fails, also free memory which was allocated previously in adpcm_encode_init().	13 years ago
Justin Ruggles	877a1d409c	adpcmenc: return proper AVERROR codes instead of -1	13 years ago
Justin Ruggles	cb023d9afe	adpcmenc: check for coded_frame allocation failure	13 years ago
Justin Ruggles	ddf70db6d7	adpcmenc: Do not set coded_frame->key_frame. It is already set in avcodec_alloc_frame().	13 years ago
Justin Ruggles	3c4add27f7	mpc7: check for allocation failure	13 years ago
Justin Ruggles	eac31dd163	mpc7: align local temp buffer DSPContext.bswap_buf() requires aligned output	13 years ago
Christophe Gisquet	e5c9de2ab7	rv40: x86 SIMD for biweight Provide MMX, SSE2 and SSSE3 versions, with a fast-path when the weights are multiples of 512 (which is often the case when the values round up nicely). *_TIMER report for the 16x16 and 8x8 cases: C: 9015 decicycles in 16, 524257 runs, 31 skips 2656 decicycles in 8, 524271 runs, 17 skips MMX: 4156 decicycles in 16, 262090 runs, 54 skips 1206 decicycles in 8, 262131 runs, 13 skips MMX on fast-path: 2760 decicycles in 16, 524222 runs, 66 skips 995 decicycles in 8, 524252 runs, 36 skips SSE2: 2163 decicycles in 16, 262131 runs, 13 skips 832 decicycles in 8, 262137 runs, 7 skips SSE2 with fast path: 1783 decicycles in 16, 524276 runs, 12 skips 711 decicycles in 8, 524283 runs, 5 skips SSSE3: 2117 decicycles in 16, 262136 runs, 8 skips 814 decicycles in 8, 262143 runs, 1 skips SSSE3 with fast path: 1315 decicycles in 16, 524285 runs, 3 skips 578 decicycles in 8, 524286 runs, 2 skips This means around a 4% speedup for some sequences.

Diego Biurrun	91bafb52ae	x86: Give RV40 init file a more suitable name.	13 years ago
Diego Biurrun	c30b198381	x86: Place mm_flags variable declaration below the appropriate #ifdef. This fixes some unused variable warnings with YASM disabled.	13 years ago
Justin Ruggles	89eea6df28	aacenc: make sure to encode enough frames to cover all input samples. Currently, any samples in the final frame are not decoded because they are only represented by one frame instead of two. So we encode two final frames to cover both the analysis delay and the MDCT delay.	13 years ago
Justin Ruggles	f44005b610	aacenc: only use the number of input samples provided by the user. Fixes handling of CODEC_CAP_SMALL_LAST_FRAME.	13 years ago
Alex Converse	48f1e5212c	wmadec: Verify bitstream size makes sense before calling init_get_bits. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind	13 years ago
