Hi,
I have a project that I made with an old version of GEM under Windows, namely a 0.90 compiled on August 3 2004 (a precompiled binary I downloaded from
iem.at or somewhere).
At that time, I had many difficulties in finding a version that wouldn't crash AND that supported dv-pal; however I did find it and the project has always worked fine.
In this project I used dv-pal-encoded AVI files and I'm not sure whether that version of GEM uses Quicktime or Directshow to open them, but I think directshow (apparently supports both).
Currently, for other projects, I usually use a more recent and stable version of GEM (still not the latest), but I had some troubles trying to upgrade this project to the new version; so, since it just works fine, I always run it with its own dedicated version of GEM, that of 2004.
I have run it in a few machines without problems, but now I have copied it into another machine and it crashes.
The funny thing is that the module that crashes is mcdvd_32.dll that is found in windows/system32, but on the machine where gem does not crash I don't even have that dll anywhere!!!!
The pd executable and gem.dll running in the 2 machines are the same: the whole "pd" folder is the same on the two machines. Obviously the patches are the same, and also the video files. There should be apparently no difference in what I am running. Both machines have Quicktime and DirectShow installed.
The info GEM prints out at startup is the same on both machines:
GEM: ver: 0.90
GEM: compiled: Aug 3 2004
[...]
pix_film: avi support
pix_film: quicktime support
In the machine that works, for every video file it loads, it prints the message
new movie might crash... ...survived
While in the machine that crashes, it DOESN't print those messages!!
It crashes when I create the gemwin (NOT when loading files).
So what is mcdvd_32.dll?
Why is gem using this dll, if the same gem on another machine is not using it (it isn't even present in that machine)?
How can I force him not to use it?
Is it possible that for some reason the working one is using DirectShow while the crashing one is using QuickTime?
Or viceversa? Why?
If I try to upgrade to the version of GEM that I usually use, the problem is that dv-pal avi's are rendered at 1/4 resolution, and I don't know how to tell quicktime to render them at full quality. I usually use mov's, so that I can put the "high quality" flag into them with QuickTime Pro; but there's no such flag in avi files, and I'd like to avoid converting all files to mov, it would take ages!!!!!
