Just installed swfdec-mozilla-0.5.3 on gentoo linux amd64 (64 bit no multilib). It works generally fine, but I noticed two things: - when playing some youtube videos, cpu usage goes to ~100% and firefox responds slowly to commands and user events; if playback is paused, everything is responsive again; - youtube video duration is always reported as 2:48 (but when playing they last the correct amount of time). If these issues are already known, please accept my apologies and disregard this report.
The duration is fixed in git (or maybe youtube fixed their player). As for 100% utilization, I've never seen it with youtube (if it's just one page).

For example, the following videos produce the problem on my system: http://www.youtube.com/watch?v=S-cV2-HWoV0 http://www.youtube.com/watch?v=SDwyBWjfFaM while other videos (both youtube and non-youtube) work just fine. While playing, they are jerky and top reports the following: top - 12:32:31 up 2:03, 1 user, load average: 0.66, 0.42, 0.34 Tasks: 77 total, 2 running, 75 sleeping, 0 stopped, 0 zombie Cpu(s): 99.3%us, 0.3%sy, 0.0%ni, 0.0%id, 0.0%wa, 0.3%hi, 0.0%si, 0.0%st Mem: 766488k total, 602516k used, 163972k free, 22584k buffers Swap: 1004020k total, 0k used, 1004020k free, 318660k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 4916 root 25 0 256m 68m 13m R 74.9 9.2 6:50.43 X 5471 shr 15 0 483m 122m 23m S 24.0 16.4 0:29.31 firefox-bin # cat /proc/cpuinfo processor : 0 vendor_id : AuthenticAMD cpu family : 15 model : 4 model name : AMD Athlon(tm) 64 Processor 3000+ stepping : 8 cpu MHz : 1800.000 cache size : 1024 KB fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush mmx fxsr sse sse2 syscall nx mmxext lm 3dnowext 3dnow up bogomips : 3591.75 TLB size : 1024 4K pages clflush size : 64 cache_alignment : 64 address sizes : 40 bits physical, 48 bits virtual power management: ts fid vid ttp Also, while doing the test I've noticed that, regardless of the video, youtube player controls (volume slider, progress bar slider) are unusable (ie, undraggable), while "pause" and "restart" button work fine. If you need additional info, just ask. Thanks
I can confirm that the duration was fixed in swfdec, since version 0.5.3 shows 2:48, but the version from git shows the correct value. But I cannot see anything wrong with those videos. They use 50% CPU (it's a dual-CPU system), but so do all other videos I have tried. Compiling swfdec with ffmep and mad makes no difference for me.

Using another, more powerful, box (athlon 64 X2), playback is smooth and CPU usage does not go above 25%. Same config (same OS, same options, same swfdec, same swfdec options) Thus it's probably a problem related to underpowered hardware (the first box is a notebook, after all). Both are 64-bit systems (running 64 bit userland binaries), if this matters. However, the volume and progress bar sliders of youtube player are still unusable. Thanks for your work!
So, I guess one issue is not a bug and the other has been solved. Should be OK to close.
The sliders not working is filed as bug 13051 - so I guess we can close it, even though I'm wondering why only those 2 files had the problem.

Well, it's not just those two. I did some other tests with the notebook, and I saw that CPU usage is always quite high on this box (always > 70%, even when playback is smooth). I mean, CPU usage varies from video to video, but it's constant for the same video during playback. For videos whose CPU usage during playback is not higher than, say, 95%, playback looks smooth. For videos that require more CPU, playback starts to be jerky. At this point, it looks like a problem caused by slightly unpowered hardware (I guess). Thanks
