With what camera are you using the driver? Is it one of mt9m001 / mt9v022
or another one? In what mode is it connected to the CPU? Master parallel?
Monochrome or colour? How many bits data bus width? Why are you writing
your own programme and not using an existing one like xawtv, mplayer or
gstreamer? It would be much easier to diagnose our problem if you took
mplayer and provided the exact command line and output.
How wrong are the frames? If they are shifted, you might have a problem
with buffer size calculation somewhere. If you get distorted images, you
might be getting FIFO overflows. Are you sending output over some library,
to the X server, or directly to the framebuffer?
See, you need to provide much more information so we could help you.
Thanks
Guennadi
