* avcodec/vp56rac: delay signaling an error on truncated inputMichael Niedermayer2019-09-11
| | | | | | | | | | | | | | | | | | A threshold of 1 is sufficient for simple_dump_cut.webm, 10 is used just to be sure the next truncated file doesnt cause the same issue Obvious alternative fixes are to simply accept that the file is broken or to write some advanced error concealment or to simply accept that the decoder wont stop at the end of input. Fixes: Ticket 8069 (artifacts not the differing md5 which was there before 1afd246960202917e244c844c534e9c1e3c323f5) Fixes: simple_dump_cut.webm Fixes: regression of 1afd246960202917e244c844c534e9c1e3c323f5 fate-vp5 changes because the last frame is truncated and now handled differently.

* VP5/6/8: ~7% faster arithmetic decodingJason Garrett-Glaser2010-08-12
| | | | | | | Grab from the bitstream in 16-bit chunks instead of 8-bit chunks. TODO: grab in 32-bit chunks on 64-bit systems. Originally committed as revision 24783 to svn://svn.ffmpeg.org/ffmpeg/trunk
* VP5/6/8: eliminate CABAC dependencyJason Garrett-Glaser2010-08-04
Create a custom table for VP5/6/8's renorm to avoid depending on H.264's. Saves one instruction in the arithmetic decoder as well. Originally committed as revision 24701 to svn://svn.ffmpeg.org/ffmpeg/trunk
