Re:AVI==>pFrame=?=>TBitmap
Thank Stefan for your answer,
but i don't need to display all frames.
I need to display a frame only if the user want it.
I have a DIB in memory and i perform some operations on pixels, like
Histogram, Difference,...
I perform this operations on many AVI.
When user say "Give me AVI #3 - frame #17", i display it.
How can i do it faster than write DIB on disk, pass from ClipBoard or
TMediaPlayer?
