Hi,
I'm quite new to OS X development. I'm tring to find out a fast way to
capture the content of a screen or a window to create a very simple
screencasting application. I tried many examples found on this list and on
other sources but it seems these solutions are too slow to capture more
then 10 frames per second. I need at least 14-15 to have a quite-fluid
movie. I saw Snapz Pro captures screens very fast so I think I can be
done, but I dunno how.
I tried both the OpenGL way (the faster) and the Cocoa way (the slowest)
(you can found the code on cocoadev.com)
You didn't provide any context of what hardware or version of
operating system you are testing on. Using OpenGL (based off of code
you can find in the archives) I can get around 30 FPS for large full
screen captures on a range of recient hardware using 10.4.
