Theora:Beta1ToDo: Difference between revisions

Revision as of 01:22, 28 September 2005

Open for Beta1

Main things from rillian's todo are:
- implement non-vp3 qi matrix support in the reference decoder
- implement per-block qi switching as per the spec
- API updates. clean up api to add theora_ctl() for setting codec options, and move non-info-header data out of the theora_info struct into theora_state

<acolwell> the encoder/decoder inloop filter mismatch should probably be fixed before Beta 1 as well (already done in alpha4?)
4:2:2 and 4:4:4 pixel format support in the reference codec

this can wait for the next beta

complete decoder?

Is beta1 supposed to ship with a decoder supporting the whole spec (comparison: Vorbis rc1/rc2)?
- Yes. See here

-<rillian> By the schedule above, 4:2:2 and 4:4:4 chroma sampling won't be supported in beta1, but will be in beta 2. Otherwise the complete spec will me implemented.
