Michael Niedermayer	0be514625a	Update golomb decoding tables so that get_*_golomb_31() return some larger values for too large values. Originally committed as revision 16299 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Michael Niedermayer	0e921e97c1	Add get_ue_golomb_31() Originally committed as revision 16298 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Michael Niedermayer	d42fc4a8ca	Use the new VLC table for the first non trailing coeff too. Sadly only 5 cycles faster here on pentium dual. So maybe the complexity is not worth it and this should be reverted ... Originally committed as revision 16295 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
