Currently, it is really slow because they have not done any optimization regarding threading. The codec is still in heavy development. Overall, I really like Xiph's goal. They aren't doing sort of trick that gives minimal gains with a big performance hit. Most people with PCs right now could not play a 1080p h.265 video @ 30fps (while using the cpu only) for this reason, despite it being multi-threaded.
I can almost play a 1080p Daala encoded video @ 24fps using only 1 core on a i7 4790. (I'll be testing this later with my PC at home, right now I'm at work and it's got Windows)Last edited by profoundWHALE; 11 August 2015, 07:47 PM.

The code to Thor is already open-source and they are contributing it as an input to the IETC for the NetVC working group.
Cisco's blog post announcing Thor does acknowledge Mozilla's work on the Daala video codec that has most of the game goals, but it appears Cisco wanted to a clean slate in designing their own free video codec.

And what is claimed isn't always right which often shows over time.

Still, if Cisco want to waste their time instead of working with VP9, it's their prerogative.

No, outside from tiny embedded systems I don't see any reason to standardize on one single codec. The code to implement all three is quite small in comparison to whatever else software runs even on a smartphone.Last edited by chithanh; 11 August 2015, 06:33 PM.

We need at least one codec that is "guaranteed" to be supported (almost) anywhere + be high quality.

There so many next gen video codecs that it starting to get hard to follow.
HEVC, Daala, VP9, Thor.
The question is which will have supported hardware acceleration, patent situation and licensing fees.

I think it is good to have multiple royalty-free video standards.
Remember with VP8, this standard was almost sunk by the MPEG LA before Google decided to pay extortion money. But the damage was already done and VP8 has only a minor role today.
Had the attack on VP8 succeeded, Theora would have been the only non-patent-encumbered codec left to use.
Now with VP9, Thor and Daala, (assuming they end up sufficiently dissimilar) even if one of the standards is found infringing, two more are still available. This gives much more confidence.
