let people contribute to specific bounties through paypal.
You have to write a Quicktime Plugin for the Ogg container and the Xiph Codec Family.
[http://qtcomponents.sf.net qtcomponents] provides support for Ogg Vorbis and MNG. This could be used as start.
All work must be released under the GPL.
=== Aggressive low-bitrate libvorbis encoding improvements for Vorbis I ===
To claim this bounty, the following criteria would have to be met:
* A 25%-or-better reduction in bitrate for quality levels -1, 0, 1 on a reasonable testsuite while maintaining qualitative equivilence (or improvement) in community testing.
* Changes under suitable license for re-integration with Xiph.Org libvorbis
=== iPod playback support ===
for useful playback.
=== Ogg Vorbis Bitrate Peeling ===
<p>Ogg Vorbis bitrate peeling has been a topic brought up time and again to combat MP3 enthusiasts. But this feature does not actually exist, only the mere possibility abounds. This bounty is set to change that.</p>
The peeler must meet the following criteria:
(optionally transcoded) Vorbis stream can be losslessly re-encoded to a lower quality setting
* Resulting streams would be identical or nearly identical to a stream generated by encoding the original source to the selected quality
* This process is reasonably fast (that is, signifigantly faster than re-encoding from source)
* Old Vorbis streams must be <em>peelable</em> already, or convertable with a utility in order to be made <em>peelable</em>
* If older streams are not natively <em>peelable</em>, old <em>unpeelable</em> Vorbis streams must be identifiable and discernable from <em>peelable</em> streams in such a way as to facilitate transcoding streams from the old format
* All work submitted must be licenced under
the GPL or compatible licence (excepting circumstances where other licences conflict) ''[Note : In the GPL-alike case the contribution couldn't be re-integrated with the reference Vorbis encoder/decoder... do we need to stipulate a libvorbis-compatible license like the BSD/X11?]''
