Choppy video on youtube and other sites.(solved)

I have upgraded to the latest pae.bfs kernel and downgraded flash to 10.2.159.1, this has completely cured my choppy video problems.

I think the crux of the problem is inherent in the latest version of flash.

Good Luck

Isn't it odd how software performs on different hardware? I'm using the latest kernel with Flash 10.3 and my experience has never been better. I can actually go full screen and back with the fglrx driver now without having to switch ttys and back.

what version you installed?

i am using 10.3 and i remember that all the flash versions after 10 have been bad(previous haven't been much better...)

about the kernel it depends on the amount of ram and the cpu you have

if you have a amd cpu not older than 2005, it is probable that you can use a64 kernel allowing you to use 64 bit extensions available on that cpu to improve performance while remaining as a 32 bit kernel, that is the one i use with my amd semprom and surprisingly with my atom netbook

if you have more than 4 gbs of ram the pae kernel could be a must have for you

the other kernels are good too, the basic kernel is the base from to compare any improvements when using other kernels

older versions of kernels rarely are necessary unless you experience problems with some hardware

I am using flash 10.3 with the 2.6.38 pae kernel and nvidea GT 220 graphics. I had to turn off hardware acceleration in Firefox to get full screen flash with the new version. The previous version of flash worked better out of the box but the quality of the videos seems better with the new version.

I also have a machine with a Celeron processor. Upgraded to the latest bfs kernel and downgraded to that flash version.  Still a slideshow for me.  Is the secret ingredient pae or is that immaterial?  I test at cnn.com/video thinking if it plays well there it can play anywhere.

@ exploder & 7272andy

Thank you very much.
I have followed your suggestions and instructions and now have the earlier flash plugin and Ta Daaa......... problems solved.

YouTube in full screen and smooth + I've just become a Full member. What a nice day it's turning out to be!
Also, all this without overclocking my nvidia card.
Thanks again for all the advise and help. PCLOS is simply the best OS out there.

Another satisfied customer.

pae only helps if you have a cpu with pae extensions and if you have more than 4 gbs of ram, if not, that kernel won't help you at all

the problem is flash, it is abusing the cpu and since you have a celeron the problem is worse, celeron is not a good cpu, is the low end of cpus

the example you gave, cnn in windowed is terrible, in fullscreen is almost usable

Agree 100%

True, but don't diss Celerons so easily.

The latest versions of Celerons (the Exxx series) has surprisingly good HD video capabilites, even with low-end video cards.

For example, I tested a Celeron E5200 (2.6 GHz Dual Core) in a Biostar G31 motherboard, with the integrated Intel video card.
It plays HD Youtube videos at 1080i in full screen without a glitch. I couldn't believe it, but I saw it myself.

In fact, I believe that these Exxx Celerons are in fact degraded Pentiums; I know that Intel does that, so it's possible.

The only problem is that it plays HD youtubes perfectly in Windows - sadly, not so much in Linux.
In PCLOS it happens just what OP says; the youtube video is jerky, but the downloaded video plays perfectly using SMPlayer.

If I can, I'll try reverting to an older version of Flash, as suggested; just to see what happens.

Celerons with their tiny cache are not really the problem.  As you note it performs well in windows - not a plus for Windows and not a minus for Linux.  Flash is written to utilize the Windows driver for video - making flash run in Linux is more like an afterthought.  Since all video decode has to be done by the CPU in Linux, a good engine is needed.

Excellent point.
In fact, that would explain another experience I recently had:

A computer with a Pentium D (the first generation Dual Cores) and an NVidia 7100 graphics card: couldn't play HD 1080i videos in Youtube. Choppy video, both in Windows and Linux.
The same system with a modern Pentium Dual Core E5700 played them perfectly both in Windows and Linux!

That's why I suspect modern Celerons are downgraded Pentiums; the video performance is much better than expected.

So, it seems the latest Flash version works well with modern processors; but it doesn't play that nice with older ones.

This trick of reverting to an older Flash might be interesting.

"True, but don't diss Celerons so easily.

the video card on the celeron is not the celeron itself, it is a video card added to the cpu

celerons are bottlenecks, new models will be dualcore with more cache and other improvements but that doesn't make them a good processor, it is the basic, the minimum, a bottleneck

"Celerons with their tiny cache are not really the problem.  As you note it performs well in windows"

in fact i have seen those perform marvelously on linux when compared to windows but still alot to desire
