Thread: OS12.2: flash uses 100% CPU with choppy playback

    Default OS12.2: flash uses 100% CPU with choppy playback

    When I go to a website using flash video's, my cpu usage goes to 100% and flash videos playback is choppy. My is powerfull enough, it's just that flash does not seem to use the GPU, but the CPU to play video. What can be done about this. This problem is very annoying since the huge amount of websites that use flash.

    Any update on this one? Chopy flash playback is very annoying because it impacts so many websites like imdb, youtube, etc.

    am I the only one who has this issue? Or am I the only one who cares?

    What sort of video card do you have? If Nvidia or ATI, do you use their
    proprietary drivers? And if you do, do you have hardware vide enabled in
    flash (which may be broken and produce wrong colors)?

    Thanks for the anwser Robin_listas

    I have an Nvidia card with proprietary drivers installed. KDE compositing, video playback, etc works great. Just flash is not. How exactly can I enable hardware video for flash. It seems disabled since it uses 100% CPU.

    When I go to Kickoff -> Adobe Flash Player. I don't have an option to enable hardware acceleration... Back in Opensuse 11.4 I had no problem with flash using same hardware.

    Right click into a flash video and choose the flash settings then you
    can enable and disable hardware acceleration.

    Ok found it, it seems that this option is not always shown, on some website the option is available, on others not. But the hardware acceleration was already enabled on those sites which allow to change this setting. So it seems that this hardware acceleation is broken with my flash. Any idea's?

    Have you tried what happens when you disable it?

    You could also try out Google Chrome (not Chromium) which comes with a newer Flash built in.

    Results with chrome are not better, disabling the hardware acceleration doesn'thelp neither. Is anyone experiencing the same issue? The choppy playback problem gets worse when the movie quality increases, espacially 720p and 1080 are unwatchable.

    I have no flash problem with my nvidia cards and high video resolutions,
    what exact model do you have and what driver version?
