huffyuvdec : implement trick
3 juin 2014, par Christophe Gisquethuffyuvdec : implement trick
When the joint table does not contain a valid entry, the decoding restarts
from scratch. By implementing the trick of jumping to the 2nd level of the
individual table (and inlining the whole), a speed improvement of 5-10%
is possible.On a 1000-frames YUV4:2:0 video, before :
