[visionegg] Re: movies

Many thanks for the movie support. I have it working in my system, but I'm
not getting high enough frame rates with my current (old) computer (I'm
limited to around 100 Hz). I was wondering if anyone has insight into the
hardware requirements for getting to the limits of my monitor (160Hz). 

Another thing I've been wondering is how fast the movies recorded with my
standard camcoder are played in VisionEgg. Are they sped up to 160 Hz so
that my half an hour movie will only last a fraction of that when replayed?
I'm also a bit worried about how long movies I'll be able to play. I'm not
sure how the VisionEgg converts the quicktime movie files into
TextureStimulus. Are they read straight into memory, in which case the
memory would be the limiting factor? I would like to play up to an hour long
movies with 160 Hz in VGA mode. Any thoughts of how this might work and what
kind of computer I should buy to get it running?

All the help much appreciated.

Hi Mikko,

I just got QuickTime movies working in Windows. I made a "Bleeding Edge"
release for Windows users:
https://sourceforge.net/project/showfiles.php?group_id=40846&package_id=7347
9
This is also in the subversion repository.

There is now an additional requirement, ctypes. (OK, there's also a
requirement to install QuickTime on your system, but you knew that...)

The old quicktime.py demo in the demos directory works unmodified on my
system.

I haven't tried my Mac with the new code and given the extent of the
changes, I'm convinced this will break Mac support for QuickTime movies
for the time being. However, this new code should be much more
maintainable in the long-term.

Cheers!
Andrew
