    Teleconferencing. If you've ever seen their UC endpoints (they look like phones, but make no mistake...they're quite a bit more...) in action, you'd understand.

    Even Xiph had tried with Tarkin which never got off the ground. They said that while it sort of worked, it would create temporal artifacts which are really jarring, and when they fix the artifacts, you lose all the efficiency or at least, all the positives to the codec.

    This was a big subject at the creation of the Mer (and Meego) project. The term is "open governance" (or proprietary governance).
    People often forget that there's more than just the code to consider in openness. For example, in my view, open and standardized protocols/formats trump open source implementation most of the time.

    There is a third codec now: NHW: https://mailarchive.ietf.org/arch/ms...AfcfqPv2_ycn20

    I hope Cisco plays balls with the h265 patents, once thor whatever comes out of it is finalized, and ask everyone some cents per use of the patents and sink that ship to the bottom of the ocean. That would drew the insane patent owners a long nose, no one would be so insane to pay that license in the future.

    Actually, it is consistent. Opus is a merging of Xiph's CELT and Skype's SILK.

    Similar here, Daala and Thor will cross pollinate, the devs will see through this process what works and what doesn't, the working stuff will then be finalized into NetVC (though they'll for sure find a better name than NetVC, but that's how the IETF working group is called). Could be even more fun if other companies also throw their tech into the mix.

    Regarding your second point, well, there's no "instead of working with VP9". You cannot. Development of the codec (not the code, mind you, the codec itself) is proprietary and owned by google, so there's no "working with". That's why they want a codec under the supervision of a standardisation group, not a single company.
    Fwiw, Android is in the same spot: you can see the code after it's released, but you cannot actually contribute features or participate in development in any meaningful way.

    And frankly the rank and file doesn't care about codecs, they just want their content. The xiph guys seem to realize this.
