separate video performance page sounds reasonable to me. However, I
generally like to be conservative about what I promise. The values
you see in the FAQ's video performance table are only a few months
old, circa version 45.5 (45.7 is now out for testing), since there
was no MSE support in the browser prior to that.</p>
<p>The watch_popup URL change just redirects to an embed URL for
me, which is suboptimal because it tries to fill the browser
window. That sort of chugs performance on this 1080p screen. If you
know of a URL that doesn't do that, let me know.</p>
<p>In any case, I'd certainly like to get more samples from the
community, so if people want to contribute their personal
observations from their systems, I'd be willing to incorporate
theirs and yours into a new video "expectations" page. I'm glad the
browser works as well as it does for you and do post the results
you get from your own machines. I assume these run 10.5 also?</p></div>Cameron Kaisertag:tenfourfox.tenderapp.com,2012-01-07:Comment/417456642017-04-02T23:16:47Z2017-04-02T23:16:48ZYouTube WebM: improving the video compatibility page<div><p>Hi Cameron!</p>
<p>I finally have the machines listed above with just one exception: instead of an iMac G4, I have an iMac G5 with a 2 GHz processor and 1 GB of RAM. The G5 is a pleasant and very capable machine. However, I find it best to leave it with VP8, as VP9 isn't so great. Perhaps upgrading the RAM and/or installing an SSD would improve the performance.</p>
<p>Some videos that have Content ID (such as "Silver Platform" videos for DDR gameplay or "Spinnin' Around" at Brittany Hargest's wedding) are only available in VP8, not VP9. Given this, and to facilitate multitasking, I use VP8 only. I'm thinking that Google will continue supporting VP8 for legacy and open source purposes. Do you plan to support the AV1 codec once it gets released? Will it be easier or harder than supporting VP8?</p>
<p>Currently, among my machines, both my eMac and Mac Mini lack Leopard. They have Panther and Tiger, respectively. I plan to clone my iBook G4 drive to install Leopard.</p>
<p>Take care!</p></div>Alex Perriertag:tenfourfox.tenderapp.com,2012-01-07:Comment/417456642017-04-03T19:07:03Z2017-04-03T19:07:30ZYouTube WebM: improving the video compatibility page<div><p>I haven't made a decision about AV1, but it's mostly an issue of patterning off the existing support for VP9. However, it's very likely AV1 won't have AltiVec acceleration and we'll have to do that from scratch too like we're doing with VP9 to make it practical. This is lower down on my priority list especially since I'd like to get some sort of H.264 support working first. And while I'm wishing, I'd like a pony.</p>
<p>VP8 is certainly the lowest impact on CPU of the three codecs, and it is the only video codec we offer where almost everything in the decoding chain has some sort of AltiVec support. VP9 currently just has AltiVec support for the IDCTs/IHTs/IADSTs (though this is the major amount of work required to decode frames) and a little bit in the convolver; I need to finish the intraframe prediction work I've been half-heartedly doing as I have time.</p></div>Cameron Kaisertag:tenfourfox.tenderapp.com,2012-01-07:Comment/417456642019-06-06T23:12:40Z2019-06-06T23:12:42ZYouTube WebM: improving the video compatibility page<div><p>I'm not sure if you'll notice my comment, as this thread is over two years old, but you may know that YouTube still has VP8 internally. It's just that from my experience, the website no longer serves VP8. (I've had a frustrating experience at a train station's computers, which included outdated browsers.) The youtube-dl tool allows still offers VP8, Vorbis and more. Were you thinking of patching TenFourFox to maintain VP8 on YouTube, or do you prefer MP4? (I know that MP4 above 480p will hiccup in QuickTime on my iBook G4; the same can be said for VP8 and Theora video.)</p></div>Alex Perrier
