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
Paul B Mahol	0a3a69e8d7	ffv1dec: use correct linesize Apparently this did not break anything. Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Michael Niedermayer	146ef3f37c	pngdec: fix warning about pointer types Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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

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.

Michael Niedermayer	9729f140ae	diracdec: Fix integer overflow leading to out of global array read. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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
