Discolorations in 3DO Videos
« on: October 22, 2006, 04:08:30 am »

I recently got my hands on a 3DO CD of SC2.  I followed the instructions of the UQM Wiki, and I was successful in adding both the intro and victory videos.

However, I have reached a problem on a few occasions; the colors on the videos have been discolored:


Correct Colors


Incorrect Colors

The quick fix is to copy the video files again, after deleting the old files.  This problem occurs when I change the resolution of the game (e.g. from windowed to fullscreen, etc.).

Sometimes the problem fixes by itself.  But occasionally the videos will be discolored again.  I just wanted to post it in case anyone has this problem, they're not the only one.

I was just wondering if there is a permanent solution to this problem, or if a bug report should be made.

The bug database is down for upgrades right now, but IIRC the DUK decoder isn't properly reinitialised when the screen colour depth is changed or when switching between OpenGL and framebuffer mode. This is a known bug. If this is what you're experiencing, restarting UQM should fix the problem until you change the settings again. Using command line parameters to change settings should also circumvent this problem. If you're just switching between windowed and fullscreen mode, try setting UQM's colour depth setting to match your desktop.

When the discoloration has appeared, have you actually noticed that the video files have changed, or have you just restored them from the 3DO CD without checking whether it's necessary? As far as I can tell, the video files shouldn't have changed at all.

To be honest, I never actually checked if the files have changed.  I made all the slides contents read only, to rule out that the files have actually been changed, but the problem still occured.  I've noticed it switch back to the normal colors when I restart UQM, so the problem is intermittent.  I just copied the video files over, just to make sure, but it must have been the restarting that fixed it.

Also, I discovered that you can fast forward and rewind through the videos using the left and right arrow keys. Cheesy

The video files are opened in read-only mode. There's no reason why they would be modified during the game.
The bug database is actually already back, but redirects aren't working properly atm. You can find the bugzilla database on http://bugs.uqm.stack.nl/index.cgi, but don't change your links or bookmarks to it. http://bugs.uqm.stack.nl/ will be the new location. 'http://uqm.stack.nl/bugs/' will be a redirect to it. All links to specific bugs using the old location will be redirected as well.

Looks like an instance of bug 734 to me. Specifically, it looks like one screen mode is RGB and the other BGR and the DUK player is not being warned about the change.
