![]() ![]() I can't imagine that the PPC970 would be too slow, but at the same time I can see how there would be a disadvantage in not having my 4 cores available to share the load. I read on the VLC forums that the FFmpeg team is working on an AVC1 decoder and that the current incarnation of it is not multithreaded, resulting in some processors being unable to play it back. I can check for updates to Perian but the ponent that I downloaded and plopped into /Library/QuickTime didn't do much to help. Lots of dropped frames, audio and video out of sync, jittery motion, etc. It fared better than VLC, but not by much. You might check just to see how much of your resources are being taken and if you have a lot open or any intensive apps open, that might be the problem. My E6600 with 2GB of RAM and GeForce 7950GT on XP using Quicktime to play it off of Apple's site works just fine. No clue why your system wouldn't be able to handle it. I really, really, truly appreciate the help.ĪVC1 is just H.264/MPEG-4 AVC, it has nothing to do with VC-1. Sorry if I'm coming across harsh here, it's just late and I'm tired (and tired of fighting with a thousand different video codecs). Worked, but that's not exactly optimal for anything I might want to keep around for a while. ![]() I had a similar file before, a music video, that I was able to play back just fine by re-encoding to XviD with FFMpeg, resulting in a 600MB file. VLC shows the video codec as "avc1." However, researching it turns up only "avc1decoder" which is a QuickTime component that doesn't help much if at all, and a plethora of specs and comparisons between h.264 (which is called "AVC") and VC-1.īut what in the hell is AVC1? Some combination of the two? Something completely different? And why can a G5 quad, 2.5GHz, with a GeForce 6600/256MB and six and a half gigs of memory not play it back smoothly? I'm on a G5 quad 2.5GHz, so there's no good reason it should be this jittery when it plays back. I downloaded a movie trailer ("Juno") that's in 1080p HD, and it stutters like nobody's business. It's late so I'll keep this brief for now. ![]()
