| | | | | | | This may be security relevant. Based on 2 patches by chrome. Originally committed as revision 19975 to svn://svn.ffmpeg.org/ffmpeg/trunk

| | | | | | branch and save around 45k-55k dezicycles per function run. Originally committed as revision 19974 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Check codec_id and codec_type in avcodec_open(), based on ↵Michael Niedermayer2009-09-22
| | | | | | | | 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

| | | | Originally committed as revision 19967 to svn://svn.ffmpeg.org/ffmpeg/trunk
* Perform the DC prediction reversal immediately after decoding all ofMike Melanson2009-09-22
| | | | | | | | | | | 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

* Use a custom radix sort implementation instead of qsort in dnxhd encoder.Reimar Döffinger2009-09-21
| | | | | | | | | | | 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).
