The Xiph Quicktime Components
provide support for Ogg files and their related family of fully free and
open multimedia technologies in any QuickTime-based application.
Xiph.org Foundation provides family of free and fully open multimedia compression algorithms and file formats, including:
- Vorbis - high-quality/medium-bitrate audio codec;
- Speex - state-of-the-art(?) voice codec;
- FLAC - Free Lossless Audio Codec;
- Theora - general-purpose video compression codec.
Xiph QuickTime Components (XiphQT) make those compression formats available to any QuickTime-based application, e.g. QuickTime Player, iTunes, and iLife, iWork and Final Cut Studio applications.
Apple 3rd party codecs page
96x96 - should be just fine for the apple's page
265x93 - almost definitely too wide :( (other logos are 130px wide max)
130x46 - size should be OK, but doesn't look too good.
