But being one of the largest companies with patents in the MPEG-LA patent pools, they also get some money back from licensing "at the end of the day". Just by looking at the list of patents in the patent pool for h264 alone, Microsoft has 4 pages of patents there: http://www.mpegla.com/main/programs/...s/avc-att1.pdf Anyway, this is getting to be a bit off topic... ps. Judging by the signature in the footer of your post, I think you could at least mention that you work for Microsoft or are involved with them. |

Also, Skype and Xiph have joined their codecs into new open source one with high quality and low delay. Opus. It's a hybrid codec: SILK (low bitrate) + CELT (high quality MDCT encoder). It performs very good now. See the results of the last comparison in my signature. Last edited by IgorC; 20th May 2011 at 03:39. |

That is one of the reasons why Opus had chance to do well comparing to commercial AAC encoders. Those AAC encoders aren't bad but it's often to see that open source implementations perform generally better. |

Am I crazy, or is YouTube's 480p config for WebM BETTER quality than their h.264 one? I used this video as my test case:
http://www.youtube.com/watch?v=vnc-c2SCz_0 Even crazier is that the 480p FLV is 48.7MB while the 480p WebM is 39.7MB! O_o (and apparently the WebM versions even have better audio quality as well) Also interesting, if you don't have a hardware h.264 decoder, WebM uses less CPU. This is particularly noticable with older PCs, specifically YouTube's 720p WebM files can actually run well on a lowly 2GHz Pentium 4 (that is, assuming you're playing the file in a dedicated media player) while h.264 is a stutter-fest.

So I'd like to know if: 1) which VP8 encoder has become faster && more-efficient lately? 2) which VP8 decoder has finally become decently-fast? Three months ago (IIRC), last time I tried a WebM file from YouTube on my Pentium-4 through Opera 11.50, the playback dropped tons of frames, and the audio sync was simply impossible. ![]() Last edited by Midzuki; 15th March 2012 at 15:29.

What is this "that" you're referring to? Do you mean the video, the post, the WebM having better quality, or something else?
(note that I do not think I can answer your questions - I specialize in audio, and definitely not video) Last edited by Nintendo Maniac 64; 15th March 2012 at 04:52. |

WebM Experimental Codec Branch Snapshot
Looks like Google is ready to go public with work on what will become VP9 (or VP8+, it's not clear to me how radical they intend to be):

In other cases youtube gives webm higher bitrate. Like this: http://www.youtube.com/watch?v=APyr48GACzc 21.6 MB for 1080p mp4, 13.6 MB for 720p mp4... And 33.0 MB for 720p webm. Lol. |

Note that, in particular, 480p h.264 uses 'Main' profile rather than 'High'. EDIT: Take a look at these two images - I can't read Russian, so I can't make a comparison-thingy like you did (note that both images have 200% nearest neighbor applied to make them easier to see): WebM H.264 It would seem that it's not as clear-cut as it is for 720p. The HUD, sky, and building on the left looks better on h.264, but the water and track looks better on WebM. The spires in the distance are a toss-up to me.
