[Libav-user] Wrong playback of frames at start

[Gonzalo Garramuno]

In my viewer, I have a problem playing avi and mov files in that the 
second and third frame are not displayed and the second frame becomes 
the fourth continuing until end.
The problem, however, does not show with wmv files.

I'm guessing I have a pts/dts problem in my viewer but for the life of 
me cannot figure out what.  I am wondering if someone faced something 
similar and what would be a good way to debug it.
