YouTube videos work well except that something strange happens about once every 10 seconds. The video will freeze for one or two seconds, and when it starts going again, there is no sound. Pausing and then unpausing the video seems to bring it back. I can work around the problem by double-clicking the pause button every time it starts to freeze. As you can imagine, this is an annoying solution. Anyway, let me know if there's anything simple I can do to give you more information. Thanks for your hard work on swfdec; I really appreciate it.
Yay, a Heisenbug. I've never heard of a problem like this, but it might be related to hitting 100% CPU load and some garbage collector (maybe Swfdec's internal one, but X might be reclaiming texture memory from the driver, too) running periodically. The suggested method to get this fixed is upgrading to a faster computer. ;)
I thought this was more popular :) From my own experience what i see is that rendering costs a lot in term of cpu time (mostly pixman) and there's a sort of underrun because it steal cpu time to download stuff. FYI here cpu time is around 30% swfdec and 70% X with radeon driver and xaa acceleration.
CPU is definitely an issue. Firefox uses 90% or so of the CPU when I'm watching a video. In fact, Firefox still uses 60% of the CPU even when the video is paused. It can't help that I can only use the nv and nouveau drivers, neither of which are super fast. (the problem happens with both nv and nouveau) Anyway, upgrading sounds like a great idea, but I don't have that kind of money right now. I agree; it would be nice.
Andrew, can you give 0.8 a try please?
Riccardo, I just looked at koji, and the latest build seems to be swfdec-0.7.4-1.fc10.
No hurry :) one thing you may want to try is using a version of pixman more recent of 0.11.2 which started shipping some altivec optimization.
Andrew, just looked to koji, you should find both pixman 0.12.0 and swfdec 0.8.0.
With pixman 0.12.0 and swfdec 0.8.0, Youtube videos are now playable. They're still a little choppy, and the sound will occasionally make a loud blip, but it's a huge improvement.
Cool, you are now on par with me in swfdec playback smoothness :). The next boost in performance will from nouveau exa acceleration work i think; major releases of cairo usually helps too. So i'm closing this because it's more matter of the ecosystem rather than swfdec itself.
