Hi everybody, I've updated OggIndex to now output Skeleton 4.0 tracks. The differences between Skeleton 3.x and Skeleton 4.0 with OggIndex is: * The fisbone packet now includes a "Radix" field. * The fisbone packet now includes two new compulsory message headers; "Role" and "Name". *...

Rerun with '--vorbis-index-reserve 313' to encode with the optimal sized vorbis index, or use OggIndex to re-index.

...is year? The deadline to apply as an organization is Friday the 12th. I know we have not had very high success rate, but it seems there are plenty of small well defined focused area projects that could use some love. Just the ogg-index-migration list for example: http://wiki.xiph.org/index.php/OggIndex-Migration I think we should submit an organization Application, but be strict on what students / projects we accept if any. Any other thoughts? peace, --michael

I have proposed an alternative formulation of the index packet at http://github.com/bemasc/OggIndex/blob/master/Proposed-modified-spec.txt That repository also contains a working implementation of the alternative formulation. I have reviewed the details with Chris extensively. I believe that this formulation (which I have dubbed "Skeleton A-mod" in an effort to avoid confusion) offer...

For the record, the Skeleton 4.0, as implemented by OggIndex, currently requires a multi-round iteration to produce. The encoder produces the index, then shifts the file content downstream to make room for the index packet ... but doing so changes the byte offsets, forcing the index to be recalculated. This potentially changes the length of the index, which...

Oh, sorry, I completely misunderstood. You want to make them time-parallel streams! I would merge them with oggz-merge without skeleton and then add skeleton using oggindex e.g. http://git.xiph.org/?p=OggIndex.git;a=summary . (oggindex is also available from http://firefogg.org/nightly/ ) Hope that helps. Silvia.

Using an index of keyframes also makes it easier to seek without visual artifacts - though of course robust players should be able to do that in the absence of an index.
