loc[a]lhost Posted March 11, 2007 Share Posted March 11, 2007 Hi. I've had Mac OS X 10.4.8 installed for a couple of weeks, on a Pentium D 940 @ 3.8GHz computer with GMA950. All my hardware is supported, and I have QE/CI enabled. I'm quite sure OpenGL is working too, although I don't know how to confirm it. However, there are some issues with video playback. First of all, if I add a text track to a movie in QuickTime and play it fullscreen, there are a lot of frame drops. It doesn't matter if the subtitles have a black background or not, or if theyhave text anti-aliasing enabled. Also, if I enable pan scan in Movie Time (which is QuickTime based, AFAIK), there are frame drops too. In both cases above, the video also appears very pixelated in fullscreen. What could cause this? I know the GMA950 is pretty weak, but it can't be to not even support proper video overlay. I'd like to know if anyone has similiar issues. Thanks.

loc[a]lhost Posted March 12, 2007 Author Share Posted March 12, 2007 Update: I checked it with a friend who has a GeForce 6600, and he has similiar issues, so it's not the GMA950 I guess. (We both have QE/CI working, so there is graphics acceleration). Could someone with a real Mac check this out and report the results? Here are 2 sample movies to check with: http://www.localhost127.net/dropbox/SampleMovies.zip One has a text track attached and one doesn't. The one without the text track works fine, but the other one has a lot of dropped frames in fullscreen.

hecker Posted March 12, 2007 Share Posted March 12, 2007 (edited) Will do. In the meantime, you can subjectively check if you have acceleration by running a 3D screensaver. hecker Edited March 12, 2007 by hecker Link to comment https://www.insanelymac.com/forum/topic/44949-video-overlay-doesnt-work-well/#findComment-321886 Share on other sites More sharing options...
loc[a]lhost Posted March 12, 2007 Author Share Posted March 12, 2007 Flurry runs fine. I also tried the demo of PREY and it works as expected on a GMA950 (less than 5 fps, but I can see things clearly). Flurry runs fine.

hecker Posted March 14, 2007 Share Posted March 14, 2007 (edited) Sorry for the delay. I tried your files and they both play fine. The texted file seems a little rougher than the other, but other than that they work fine. I don't know about your video card's abilities but I had some problems with video playback on my G3 Powerbook and the only solution I found was to use a video player named Chroma. It's really fast. PM me if you need more info on chroma. hecker PS: That was a pretty sweet video, are you in the Air Force?

loc[a]lhost Posted March 14, 2007 Author Share Posted March 14, 2007 Thanks for testing it. I would like to know what your resolution is. Mine is 1680x1050, which is quite high, so this might be the issue. And I'm not from the Air Force, it's ust a sample video from the DivX site.

hecker Posted March 14, 2007 Share Posted March 14, 2007 My hacintosh resolution is 1240x1024. Did you try chroma out yet? hecker Link to comment https://www.insanelymac.com/forum/topic/44949-video-overlay-doesnt-work-well/#findComment-323916 Share on other sites More sharing options...
loc[a]lhost Posted March 15, 2007 Author Share Posted March 15, 2007 There are many players, but nothing in OS X is as compatible as QuickTime. For instance, I'd like to have my movies subtitled in Front Row and iTunes, without reencoding them and losing quality. I have tried to play a movie with a text track in Movie Time, and it has the same issues. Probably any player that uses the QuickTime framework would be like that.

hecker Posted March 15, 2007 Share Posted March 15, 2007 Chroma and VLC do exactly that hecker Link to comment https://www.insanelymac.com/forum/topic/44949-video-overlay-doesnt-work-well/#findComment-324315 Share on other sites More sharing options...
loc[a]lhost Posted March 15, 2007 Author Share Posted March 15, 2007 Do what? Play subtitled movies without reencoding them? I know that. But unless the subtitles are in the QT text track, they won't be shown in iTunes or Front Row.
