Got a tip for us?
Let us know
Mini G4 OpenGL capabilities on Tiger
- Thread starter asiga
- Start date
oh? I thought in another thread you said anything below the 9600 doesn't support it. I must be mistaken.
All versions of OS X can use OpenGL for GUI compositing. Even a Rage 128 supports OpenGL. Quartz Extreme uses OpenGL more extensively and that works on any AGP Radeon.
I'm thinking you are getting OpenGL confused with Core Image.

so would that explain why when i download web videos they RealPlayer, NicePlayer or VLC lag but QT plays it smoothly? Would i need to use the Ten4Fx QTE and play videos in QuickTime to see it at 720p?
Not all MPEG videos are the same. Only MPEG 1 and 2 are lightweight enough to not cause problems in higher resolutions. Even with native support, a playback can have dropped frames. OS X has native playback of h264, but it drops frames with higher resolutions on slower systems.
so what Codec do u recommend? I install Perian on all my macs and have installed Flip4Mac in the past
it possible to watch 720p with the 9200 my eMac has or the 4MX the MDD has?
What the... Dude, reading this thread gave me a headache. Have you ever heard of Google? You should try it from time to time. It's pretty neat and you can find a ton of interesting stuff using it. 
And to be on topic, the eMac screen might have a high enough resolution for watching a 720p video, but i wouldn't bet too much money on that cpu/gfx card combination. It depends a lot on what codec was used to encode the video, and the lack of core image support will take its toll on the cpu.
That being said, think about the MX card and the fact that it's weaker in terms of computing power than the 9200 Radeon.

Thanks a lot for all your replies. However, my question wasn't about CoreImage (I already knew the G4 Mini doesn't support it), nor about accelerated codecs, nor about the "user side", but about the "developer side" of the world.
I'd like to know the extensions, maximum values, etc, supported by OpenGL on the G4 Mini with 9200-64Mb at Tiger (10.4).
Apple keeps an "OpenGL capabilities" chart, and it had a column for 10.4, but they removed all old OS X versions from the chart, and I cannot find any backup on the web.
A GLinfo output would also help. Anybody has any of this for this machine?

I just found it! You can find the OpenGL capabilities of several OS X versions, from 10.2.8 till 10.9 (and Tiger included) if you search for the old URL http://homepage.mac.com/arekkusu/bugs/GLInfo.html on the Internet Wayback Machine (that page no longer exists, and the current GLInfo version you can find doesn't cover old OS X versions, but if you look in the Wayback Machine, it's there).
