Thanks, when using OverrideGPUValidation=true, Xorg CPU usage drops to near zero when playing Youtube-movies in fullscreen :) It's definitely smoother. However, when going back to normal, from fullscreen, the graphics hangs in fullscreen (sound continues), and firefox needs to be killed. Damn, cause it really helps CPU usage :/.

AMD Catalyst 8.7 Linux driver, ATI X1400 128MB graphics (DirectX 9 class), Ubuntu Hardy 32bit, no Compiz.

What about XRender 2D acceleration? Firefox3 uses it for web page rendering (using cairo library which is accelerated by using XRender). XRender is perfect way for hog slowly flash to make it really useful or worth enabling without wasting 100% CPU for dumb adverts playback.
To make it clear: XRender operates on RGB, flat 2D graphics so it is worth checking. I watch flash for Linux development since a long time. You really have troubles with weak performance. Give up on trying improve flash performace and focus on passing this hard task to external libraries which have success on this field. Cairo is good start point. It has 2D acceleration via XRender and can be alternatively OpenGL accelerated using glitz.

[ Oh goodie, another Linux API. I didn' think there were enough already. -Mike M. ]

I see flash 10rc crashing on the following site everytime i load it:
http://www.thedailyshow.com/

The interesting thing is that the page loads fine and i can even start the video but after 3-4 seconds flash just dies (even if I don't click anything on the page).

BTW does there exist a debug build of flash somewhere so I could get a reasonable good backtrace of the crash?

[ Yeah, engineering debug builds exist. But we keep them internally. -Mike M. ]

Thanks, this is quite handy for those of us testing support for Flash.

This doesn't work for me (on Linux). Playing a YouTube video in the small window still consumes 90% of my CPU. Trying to play fullscreen turns it into a slideshow, at about 1 frame every 15 seconds.

However, if I download the flv from YouTube and play it in mplayer, it plays fullscreen no problem, with the CPU at only 30%.

Maybe you want to detect common media players. Just stop playback in the browser and hand off the video to mplayer, xine or vlc if they are available.

Otherwise, you've got a lot of work to do re-inventing the wheel.

Doesn't work for me either. Full-screen is even slower than before (and that was slow)!

You supposedly don't use Xv because it only supports YUV and not the RGB that you require--although the gnash person said most cards support it... but anyway. Why can't you use OpenGL? Mplayer has *two* different OpenGL video output modes and they both work fine on my system. It surely has enough flexibility to meet flash's needs, and colour conversions are pretty trivial using GLSL.

Given that flash is mainly used as a video player these days it's pretty shit that it can't even play low-res video full-screen.

[ We do use OpenGL for fullscreen output. -Mike M. ]

For the few of us that don't always have root access to the machines we're working on, is there a home directory location for this configuration file apart from the system-wide one in /etc/adobe? If not, could we please have one?

Sorry to abuse this comment thing, but I still don't get why MPlayer's OpenGL video output can play 720p content fullscreen completely smoothly, but flash can't even play low-res youtube videos smoothly fullscreen. I'm pretty sure it works on Windows but I'll have to check that...

"And if you are planning to ask about Xv support, read the post again until the message clicks."

Maybe you should read the comments on that section until it clicks, or until you can provide a better answer. Specifically:

"I added XVideo support to Gnash; it's not that difficult. Most video cards support an RGB format, and if they don't then the algorithms to do rgb->yuv are fairly simple and fast."

Can you explain why this is difficult for you, but not for Gnash?

Could you be a little more descriptive on where the cfg files goes? ~/mm.cfg or ~/.mm.cfg?

[ No dot. It's not a hidden file. -Mike M. ]

Thanks for the information, I feel sorry for you having to work on the abortion that is the Linux platform(s).

I'm not surprised to find that Flash on Linux runs slowly, yet runs fine on every other platform. That's because other platforms have a consistent set of stable APIs.

[ Oh goodie, another Linux API. I didn' think there were enough already. -Mike M. ]

LOL, this is so right.

Oh and Mike: 64BIT?!!1!1eleven

Is anyone else tired of Mike's snide responses to valid suggestions?

[ Not as tired as I am of explaining why said valid suggestions are, in fact, invalid, I guarantee. -Mike M. ]

"And if you are planning to ask about Xv support, read the post again until the message clicks."

Thanks for the condescension. Oh, and the terrible software.

1. The problem isn't with Mike, it's with the Linux Youth who fill these blog comments with tedious braying about the NextBigThing™ API in Loonix Land, demanding better performance on a platform designed for server use, which is mediocre (at best) on the desktop. He's talking to delusional idiots, of course he has to be condescending.

2. Flash works fine on every other platform. Anyway, even if it did suck (which it doesn't), Linux users should be happy Adobe devote any resources to Linux at all. Particularly considering all Linux's desktop market share has just been taken by Windows 7. What're you going to do, storm in with your 0.8% worth of the desktop market, demanding better recognition? Pathetic.

Why don't you people go off and work on Gnash instead of whinging? SWF is an open standard. Oh wait, like the GIMP, Scribus and Flashdevelop, Free software clones are universally a disaster and at least 15 years behind their proprietary counterparts.

This sense of privilege and expectation of preferential treatment from the Free software community needs to stop, now.

Dear Ken,
If you like windows so much, why do you bother reply and offending people on a linux blog? If you think linux is only good for servers probably it means that you have not perceived the great advantages that linux give you as a workstation for developing and data analisys purpouses. Why peoples that do hard computing work should accept a piece of ultra slow crap like Adobe Flash on linux?

Why people that are not paid should spend time to develop opensource alternatives to a crap like Adobe Flash on Linux?

If Adobe would free up Flash or simply hire a couple of real programmers, you would be sure that in a couple of month and some basic optimisations it would run flawlessy and fast as mplayer.

Wow Nick, u are sooo clever.

1 percent is still means 20 million users, think about that. I like these troll comments everywhere in linux topics. What a shame, we want to use open source software, and get to know, how our system really works. We must be idiots, because we dont like viruses, slowing systems that must be reinstalled every year to work correctly, full of with security bugs. U are soo brave, you should be proud to be a MS user ;)
