Is this happing with all files ?
Avifile has special frame dropping scheme which will avoid to
drop already decoded frames - if your movies is made by some intelligent
person (so the keyframes are at 5s steps at most) this dropping algorithm
should be giving very good results - if you want to drop already decoded frame
- try to change this:
if (async < -4.0 || (async < -0.15 && m_Drop.average() < 4))
to:
if (async < -4.0 || (async < -0.15 && m_Drop.average() < 50))
in the aviplayth.cpp - let me know if this has solved your problem.
(try to find lowest such value)
