Given this is a presentation from the VP9 conference, it's surprisingly full of digs at VP9 as a technology and a process throughout. Anyone who's read this much really should read the deck. It's good. There's lots of interesting ideas in there, but it's waaay too early and raw to make any kind of prediction for how it'll stack up against HEVC or other alternatives. |

https://en.wikipedia.org/wiki/List_o...top_processors For reference I can decode 1280x720 30fps HEVC with "only" around 70% CPU usage on my 2.5GHz Brisbane (65nm) via MPC-HC v1.7.5 32bit. Compared to the original 90nm Athlon 64 x2 CPUs, the 65nm Brisbane CPUs have half the L2 cache which, as Tom's Hardware determined, results in them being slower than the original 90nm versions: Quote:

If it passes VP8 on still images, then it's already made WebP obsolete.
That was fast, and now it gives Mozilla more justification for not supporting WebP. Last edited by Nintendo Maniac 64; 10th July 2014 at 07:44. |

More or less good but at some samples Daala artifacts (repeating not natural patterns instead of fine detail on textures; I am not sure to call this ringing which was mentioned as current Daala primary fault) looks visually (dunno about metrics) very annoying even in compare to VP8 blurring or JPEG blocking. You can see such artifacts in full resolution samples:

It also smudges things more on other parts. |

I believe the "ringing" in question may be the artificial noise that was mentioned in the slides just a few posts up. Such artificial noise was also mentioned in the video posted on the first page of this thread.

Anyone can write their comments and conjectures on the parallel forum > Daala-vs-HEVC

So, uh, it was just called to my attention that VLC supports decoding and encoding of Daala now (in git). The decoder and demuxer were committed on August 28th, the encoder was committed 5 days ago. It's disabled by default, but yeah.
It's been a long, long time since I've messed with compiling VLC (and only did so with a native Linux build), so I'll have to brush up, but I'd consider this fairly significant in general. It's almost certainly more comfortable than the example player in the Daala source code. Last edited by qyot27; 27th September 2014 at 02:57. |

Sorry, I have a real bad habit of doing that. I used it on linux, but futzed with mingw until I started working on another project and forgot all about it. I got it to build properly now, but it's dynamic, sorry about that. I have no idea how to make static builds.
