Quartz 4.0 exporting live video input composition for quicktime...

Timesquid's picture

Hi, Im trying to get a functional Quartz composition with safe video input and midi input working in modul8... Ive got a composition that should work, but when I use it in any other application, its dark, and reacts to the midi differently.. Any ideas?

Ive attached it... you will need the vade plugin http://002.vade.info/?p=32

and the safe kineme midi and video patches...

Im using Quartz 4.0, snow leapord, and quicktime Pro...

Is it just not possible with these builds?

Also... This plugin - stoped working when I upgraded to 4.0 Quartz... is that avoidable, or does Tom B have to upgrade the plugin for 4.0 functionality? :

i think the datamosh plugin runs in 32bit.

Your right about the datamosh... I got it working... but no luck exporting a functioning quicktime with video input... Are there procedures I need to take to make this sort of thing work? Any troubleshooting ideas, The QT exports for anything with live video just dont work for me, I feel as though there must be a simple problem... to enable a fix.

PLEASE!!! anything?

I don't know if it's related but ...

I work a lot with a 3rd party QC capable video application called CamTwist. Under QC 4.0, the Video Input patch will not recognize CamTwist as an input source in 64-bit mode (although it does still work in 32-bit mode). I asked the app's developer if he could release a 64-bit version of CamTwist and he informed me that the issue was with the application's QuickTime component. He said that Apple now uses a new private unpublished application programming interface for video access in QuickTime and that there wasn't anything he could do until Apple publishes that API.

The number of issues with QT and 64bit is stunning. If you disregard QuickTime, apple's handling of 32 to 64bit was absolutely breathtakingly flawless -- it out did windows migration, and it soundly spanks Linux 32/64bit migration as well (in terms of writing and deploying software).

But QuickTime is in horrible condition. It's kinda weird, given how everything else went so smoothly (Cocoa, QC, CoreImage, WebKit, basically everything else)... not sure why that is...

Ok, I just tried Quartz Cyrstal, It export does not load the video input... its just a black composition. How do you excecute a functional video input into a quicktime... anything major Im missing here, do I need a special patch in my composition to secure the video input.

Ive got Safe video input and all that...

Maybe I need to get all the patches to be "safe"

Yeah. I just installed the ManyCam virtual cam application for a comparative test. It's useful for screen captures when streaming. Anyway, ManyCam appears to share the same limited access circumstances as CamTwist; the QC Video Input patch can access it in 32-bit mode but not in 64-bit mode, probably for the same QuickTime related reasons.
