  • Spec is finished

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

this can wait for the next beta

  • add some sort of mmx(?) wims,VP3HoSwiYO or rodolphes sugestion?
    • There is a branch of theora-lib with MMX optimization for encoding: theora-mmx.
    • Also there is an experimental theora library supporting the whole spec and having also MMX optimization for decoding.

complete decoder?

  • Is beta1 supposed to ship with a decoder supporting the whole spec (comparison: Vorbis rc1/rc2)?
