Hi everyone,

I was wondering how well 'use internal display' is working for people now. I know that for some graphics cards the colours come up wrong (green and blue), and I'd like to find out how widespread this is.

In theory it should now work for everyone with cards that can handle 4 or more texture stages. I can probably get it down to three but I'd first like to find out where it's at.

{P^/

btw I know I could use a poll for this but I want to see ppl's individual answers.

After concluding that my signal is weak (should be fixed by the weekend:) this is what I see when "Use Internal Display" is selected. Hopefully this is only a signal strength issue.

Hmmmm... it looks like something else is going on there too... that's a pretty weird picture :)

I'd be interested in any call stacks when iTele crashes like this - they're the sort of things that I should fix as they turn up (i.e. it should really never crash due to bad input). You can copy the call stack out of the window that comes up when you offer to send the crash dump to Apple.

It works fine for me... only problem I have is Full Screen doesnt work. Should it if using internal player??

Cool. And no, I haven't done fullscreen with internal display yet... have to figure out which resolution to use and all that... I'll get round to it one day.

Internal display will only work for me as an audio source. There are some differences in video output.
HD channels give me a huge white window with some discernable but pixellated images within with a bluish/green tinge.
SD gives a smaller white window with no discernable image - resizing is disabled for both HD and SD windows.
I am running 10.3 on a 800mHz G4, AGP capable with an ATI card, 256mB SDRAM.
Question:
What is the idea behind internal display- was it to avoid the use of external media players like Mplayer

Yes that is the reason behind internal display, so the display is more within the contorl of iTele. What kind of ATI card do you have? Currently the card must support 4 texture stages. Also try turning off 'Use ATI text fragment shader' from the preferences and see if it makes any difference.

Mine is an ATI Radeon 7500 which does not have those preferences.
I presume the 8500 and later models can do this Confused

Actually, everyone has those preferences. I'm talking about the Preferences in iTele. You know, from the iTele menu. You have the option to turn it off no matter what card you run it under.

Oops!

No, it still does not make any difference to the effects described above.
Do I need better hardware?

BTW, Mpegitor displays the same 'white screen of death' in the edit window. I can hear it but I cannot see it - shame, I was looking forward to using a better one step editing approach than Project X.
If I can delete one step in the dvd conversion process, that would be great.

OK I've looked up the 7500 and I agree that neither technique I use should work Smile

It certainly doesn't have fragment shaders and it only has 3 texture stages. Plus the blend ops I use to double the brightness are not supported too.

However there is another technique which appears to be supported by every renderer (i.e. card), right down to the Rage 128 ... I assumed it was more difficult and less supported (the OpenGL extension does have 'SGI' in its name :) but I guess I can give it a try. Although, just because it's supported doesn't mean it's not unusably slow of course, but since it's very simple (for me anyway) I'm going to give it a shot.

Stay tuned (hehe ... err.. hmmm)

What Atomic got, at the top of this topic, with the strange split up screen and mess in all but the top right quadrant, I now have. It's consistant - restarting does not fix it. It even goes wrong if I run iTele from source code. This is on a dual 1ghz machine with a nvidia gf4 4600

I've done two things since (i think) it was last working okay: Firstly, I installed 10.3.4 and then I moved the location of my home directory (from somewhere weird, back to /Users).

Atomic - if you're watching this topic, did the problem go away for you?

Cheers
