Aurelien Jacobs	2a2311bee3	disable vp3 mmx idct for theora files to avoid artifacts (see theora-a4_v6-k250-s0_2.ogg) Originally committed as revision 6253 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Diego Biurrun	7f889a76ad	Remove the LGPL exception clause as discussed on ffmpeg-devel and move the dependent code under CONFIG_GPL. Originally committed as revision 6248 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Aurelien Jacobs	1dac8fea05	Enables back the mmx/sse optimized version of the vp3 idct. It generates different md5sum than the reference C implementation, but no visual difference, so enabled only when bitexact is not set.
