Apple Seeds QuickTime 7.6 to Developers, No H.264 Acceleration Yet
Apple seeded a new version of QuickTime 7.6 to developers yesterday. The latest build is available for Mac OS X and Windows and asks developers to test AAC encoding/playback, Multichannel encoding, Apple Lossless playback/encoding as well as MPEG-1 playback/encoding.
With recent news that the new MacBooks and MacBook Pros appear to have hardware based H.264 decoding, readers are going to be naturally interested to see if the latest QuickTime beta might include such support for older Macs.
The latest seed, however, shows no drop in CPU usage when decoding 1080p QuickTime streams on a previous generation MacBook Pro. It's still not clear if Apple will incorporate support for H.264 hardware decoding on older Macs, many of which contain GPUs capable of some level of H.264 support.

In before Apple saying it only works on the new laptops since they're special. :rolleyes:

If they would make it work with the current Macs we'd have one less reason or to purchase one or maybe to update our OS to 106 Snow Leopard.

If they could implement more advanced software decoding like coreavc I don't think people would be as concerned.

It's coming. Snow Leopard will mean Quicktime 8, which means another $30 to make it Pro.

This seed. Although it's supposed to be under a strict NDA is focused on variable bitrates for multi-channel encoding. In otherwords it's mainly for audio not video. They want to test things like 64KBps in the front channel and say 56K in the left rear etc.
Don't go getting all scared now kids.;)

Acceleration likely needs new video drivers in the next os update.
Or, the speed bump could be functionality built into the new chipset, something the previous controllers lack.
I actually hope this isn't the case. I would really like to see this hardware acceleration work for all Core image / Quartz extreme enabled GPUs. This would give a 2nd live to G4 and G5 systems, however that is not likely since Snow Leopard is to be only Intel :( .

H.264 hardware encoding in Macs. Just bring your old Mac to the store and they'll install a new gpu in it. $50/customer.
Seems to me the support is there in new MBs because of the new chipset/gpu.
