Michael Niedermayer	4cda8aa1c5	avformat_new_stream: fix initial last_dts value Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Alex Converse	fd0be63049	tiffdec: Prevent illegal memory access caused by recycled pointers. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Tomas Härdin	f6daa9f4f6	mxfdec: Add intra_only flag to MXFTrack This allows future assumptions to be made without affecting non-intra files. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Tomas Härdin	8c7721e709	mxfdec: Fix Avid AirSpeed files being misinterpreted as OP1a The "ECs != 1 -> OP1a" assumption was wrong. Luckily, the file that triggered that behavior had two ECs, not zero. Hence distinguishing between them is simple in this case. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Tomas Härdin	bf2290a80c	mxfdec: Truncate packets that extend past the next edit unit This fixes rare cases where OPAtom may be treated as OP1a, causing all essence to be read into RAM. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	f64cfba93b	libavutil: document av_force_cpu_flags(-1). Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Martin Storsjö	94f1b11a6f	rtpenc: Fix the AVRational used for av_rescale_q_rnd The current one has a zero denominator - this is what was intended in `14aecc50fa`. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Nicolas George	78306c51ef	ffmpeg: show fps more accurately when it is small.	13 years ago
Nicolas George	a8cdb7b95a	swr: special case for empty channels in rematrix. Speed += 10% overall for pan=stereo:FL=FL+FR from wav to null.	13 years ago
Ronald S. Bultje	b4bccf3e4e	wma: fix off-by-one in array bounds check. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Reimar Döffinger	6eda85e15b	sbrdsp.asm: convert all instructions to float/SSE ones. Since the values are floats, using the float operations makes sense, improves performance on some CPUs and makes the code SSE compatible instead of needing SSE2. Based on suggestion by Jason.

Ronald S. Bultje	93b53ffb1a	dca: don't use av_clip_uintp2(). The argument is not a literal, thus causing the ARM v6 or later builds to break.	13 years ago
Ronald S. Bultje	626964a4c4	wmall: fix build with -DDEBUG enabled.	13 years ago
Ronald S. Bultje	8febcb9fc1	smc: port to bytestream2 API. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Christophe GISQUET	7e1ce6a6ac	dsputil: remove shift parameter from scalarproduct_int16 There is only one caller, which does not need the shifting. Other use cases are situations where different roundings would be needed. The x86 and neon versions are modified accordingly. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Christophe GISQUET	dabf8dd34a	SBR DSP: unroll sum_square The length is even, so some unrolling can be performed. Timings are for x86: - 32bits: 102c -> 82c - 64bits: 82c -> 69c Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Christophe GISQUET	294c05ce8a	rv34: remove dead code in intra availability check This was an incorrect copy-and-paste to a code not needing the original code. Spotted by Jason in a previous review but forgotten in the commit. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago

Nicolas George	c088b7f389	ass_split: accept files with only \n and no \r. The +1 is there to skip the ','. With \r\n, the +1 skips the \r but that is ok. With only \n, the +1 skips it and all hell breaks loose.	13 years ago
