I just saw mention in another thread (h/t MrPilot) that there is a new version of VLC. I've tried a couple of 1080p files on my MDD with this new VLC (version 2.0.8) and was absolutely amazed. I'm getting better performance than with CorePlayer with the files that I tried (H.264, 1920 × 1080, Millions AAC, Stereo L R, 44.100 kHz mp4 container). In VLC, I have "skip the loop filter for h.264 decoding" set to "all." This is supposed to degrade the quality, but I didn't notice a difference picture quality between VLC and CorePlayer using this setting. I suppose that could vary depending on the quality of one's eyes and display. No missed frames in either case, but VLC is using 10 to 15% less CPU than Core Player! CPU use fluctuates through the whole movie, of course, so I'm trying not to overstate this since I can't pin down an exact number, but VLC was hovering in the low 70s and Core Player in the high 80s. My machine is running 2 x 7455B @ 1.58GHz. This has to mean that they've restored some of the AltiVec code that was originally disabled in version 2, right? Maybe even improved on it? I'd love to see others who have Core Player do some comparisons with the new VLC. All of my 1080p is encoded exactly the same way, so I'm not going to get much variation. If this pans out, who needs CorePlayer? VLC has always been way better in every other way. May I humbly suggest that anyone who wanted to purchase CorePlayer, but didn't get it in time (or tried to buy it and had their money refunded, as I've read a couple of times here), please consider donating that same money to the VideoLAN team. Who else continues to improve things so much for our beloved PowerPC machines?
