Michael Niedermayer	9062cd3544	Check validity of channels & samplerate. This may be security relevant. Based on 2 patches by chrome. Originally committed as revision 19975 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Mike Melanson	428984b041	Another micro-optimization for unpack_vlcs(): Eliminate a possible branch and save around 45k-55k dezicycles per function run. Originally committed as revision 19974 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Michael Niedermayer	4c0dda2b3f	Check codec_id and codec_type in avcodec_open(), based on 43_codec_type_mismatch.patch from chrome This is said to be able to lead to a stack based buffer overflow. Originally committed as revision 19973 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Benjamin Larsson	61dc238b45	Hook up the MD studio demuxer and Atrac1 decoder. Originally committed as revision 19969 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Benjamin Larsson	e704b012f2	Mention SDDS so search engines will pick it up for when someone needs to decode the SDDS tracks found on 35 mm movies. Originally committed as revision 19968 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Benjamin Larsson	edd897b1b3	Use ff_sine_32 in atrac1. Originally committed as revision 19967 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Mike Melanson	138fe83215	Perform the DC prediction reversal immediately after decoding all of the DC coefficients. This has a greater probability of leveraging the coefficients while they are still cached. When testing with the Big Buck Bunny 1080p video, I consistently saw improvements of 500k-600k dezicycles per run (through reverse_dc_prediction()) thanks to this move. Originally committed as revision 19966 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago

Diego Biurrun	523ef55119	Deinterleave the generation of config.h and config.mak. As a sideeffect this moves more interesting variables to the top of config.mak. Originally committed as revision 19950 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Reimar Döffinger	40e26453c4	Use a custom radix sort implementation instead of qsort in dnxhd encoder. This is mainly to avoid test failures due to implementation-defined behaviour of qsort when elements are equal, giving different results for each of FreeBSD, Linux/glibc and Solaris. In addition it is about 35 % faster, effect on overall speed is minimal though (< 2%). Regression tests are unchanged (i.e. identical to Linux/glibc). Originally committed as revision 19949 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
