Ok, I'm stumped.

Starting sometime last night, without any intervention that I recall, suddenly any video being played by my browser ate 100% of the cpu (npviewer was taking 85% when I viewed using "top") and would not play properly.

I uninstalled firefox, vlc, xine, mplayer, flash-plugin, pulseaudio... really, everything I could imagine was involved. I reinstalled firefox, pulseaudio, and flash-plugin.

So, now it's not eating 100% of the cpu when I run a video. Instead, it's stuck on fast-forward -- it skips huge hunks of the video, blows through it at double- or triple-speed, and of course the audio comes in jerky little bursts that are incomprehensible because I've lost frames.

Apparently there's some configuration detail that I have to feed it to slow it down to standard speed. Only, I've been running Fedora here since 2007 and have never had to do this before. WTF?

Configuration details:

- Fedora core 13 64-bit version
- Running on an Athlon 64 @about 2.2 ghz (pretty fast -- can't imagine that I'm really overpowering the cpu)
- Firefox Mozilla/5.0 (X11; U; Linux x86_64; )
- Shockwave Flash 10.1 r82
- Currently have NO audio or video package installed outside of firefox (no Xine, no Totem, no Mplayer, no VLC)

What the heck is going on here? And how best should I restore just, plain ordinary playback capabilities to my machine?

Were there any updates last night before this started ? Have a look at yum history and see if you might reverse the changes.

The following updates took place automatically, by way of a cron script that I execute in the middle of the night:

Sep 08 04:40:50 Updated: 1:NetworkManager-gnome-0.8.1-6.git20100831.fc13.x86_64


I can't see any of those causing the problem I've described.

this was only for no line videos in firefox ? right
And not for ALL videos playing in totem, or mplayer/gmplayer/SMplayer-qt4 or vlc

just the online .

if so as i recall there was and is a bug in the 64bit flash

seeing as this" Currently have NO audio or video package installed outside of firefox (no Xine, no Totem, no Mplayer, no VLC)"
there is NO way to check if vlc,mplayer and the installed by default totem work fine

how then ARE you watching videos online without the
totem ff plugin( i do not use it),
or the mplayer ff plugin(mplayerplug-in.so,mplayerplug-in-wmp.so,mplayerplug-in-rm.so,mplayerplug-in-qt.so,mplayerplug-in-gmp.so,mplayerplug-in-dvx.so)
or the gstreammer - xine ff plugin(gxineplugin.so)
or the vlc ff plugin (libvlcplugin.so)

can you please post the firefox output of
so we can see just how you are watching videos on line

It affected both firefox and Opera, although it was not nearly as bad in Opera.

John VV makes a good point, so I went ahead and installed mplayer to test it from the command line. The result was that not only did mplayer handle the video just fine and dandy, but after I installed mplayer firefox ALSO handled the audio and video properly... and so did Opera.

I'm sure I should be learning something about the operation of these multimedia programs from this incident. I'm guessing that firefox gives preference to mplayer over the shockwave plugin, and mplayer contains controls for the audio/video components of my machine that do a better job of buffering than does shockwave.

Anyhow, it appears that I can now play multimedia files again, so... thanks for your help, all.

Just FYI, since you asked, though:

about : plugins

SHOCKWAVE FLASH
File: nswrapper_32_64.libflashplayer.so
Version:
Shockwave Flash 10.1 r82
application/x-shockwave-flash Shockwave Flash swf Yes
application/futuresplash FutureSplash Player spl Yes

NPAPI Plugins Wrapper 1.3.0

followed by a mime type for every java version...

for fedora this is a very very good help/guide page
it is short and right to the point
http://www.mjmwired.net/resources/mjm-fedora-f13.html
and very useful

John, thanks for the link. I'm already pretty familiar with that page, and I think you missed the part of the post that started this thread in which I said that I had, just the previous night, REMOVED pulseaudio, mplayer, vlc, and xine in an attempt to find out what was eating my cpu. That means I had all of them installed until about 2 nights ago. I was using one or more of the above to view videos, and they were working just fine until the other night. It was the sudden influx of "Oh, s**t, that isn't working for some reason" that started the current mess.

Thanks again for your help.

If this is solved, mark the thread as solved.
