Default Re: Flash acceleration on Linux?

I downloaded the tarball through gentoo linux's package manager, so I never saw the download page. Other people downloaded it via links posted on forums. Others simply guessed the download url based on what Adobe's previous URLs had been. All of those people never saw the download page to know that.

Some videos that are encoded by x264 are not played through vdpau (i played the cached file and they do use the x264 encoding). But nonetheless use ~70% CPU. Played with smplayer max 5%.

That is because this is an API inside of flash. Taking advantage of it requires swfs capable of using it. It is likely that Youtube, Hulu, etcetera will implement support for it soon, so that should not be a problem.

My suspicion was that the x264 video contains information about the level being used for encoding that VDPAU does not officially support and Flash therefore decides for software decoding.

The relevant test was the first thing removed from Nvidia's original MPlayer patch, Carl Eugen

Just for the record. I tried the flashplayer 10.2 plugin on a 32bit Windows 7 laptop sporting a 9300M GS card with the latest NVIDIA driver (260.99) and got _no_ video acceleration. The driver seems to support flash up to 10.1 only. Looks like Linux is ahead.

Well, this statement was not correct. Although the video information says "undefined video rendering" opposed to "accelerated video rendering" in the Linux case, it lists the frame rate for staged frames. So it seems to access the GPU indeed.

The recent update (flashplayer10_2_p2_32bit_linux_111710.tar.gz) broke vdpau acceleration. I noticed that over the weekend when the laptop battery drained faster than expected. There is independent confirmation here http://forums.adobe.com/message/3415486?tstart=0.

"broken" might be the wrong word, but Adobe forgot to add information on how to activate VDPAU in latest beta Flash Player for Linux:
Add the following line to a new configuration file /etc/adobe/mms.cfg
Code:
EnableLinuxHWVideoDecode=1
(http://bugs.adobe.com/jira/browse/FP-6079, http://forums.adobe.com/thread/780594)

EDIT:
There is information from Adobe (I *really* wonder how they are expecting to get bug reports if the feature is so difficult to activate): http://kb2.adobe.com/cps/890/cpsid_89050.html

Dear Carl Eugen,

thanks for pointing this out. Works like a charm now.

So just to confirm, there is no 64bit version of 10.2 with vdpau support yet?

Nope
The "Square" 64bit release from 17.11.2010 with the "EnableLinuxHWVideoDecode=1" trick mentioned above seems to use the GPU on some videos on Youtube and 1080p videos play rather smooth... maybe it does... but the video info does not say hardware accelerated

There are some issues with the hardware decoding. I get transparent gnome-terminals (the text is visible, but the background is transparent, should be black), remaining artifacts even after the browser is closed, vdpau tearing after i played videos via flash.
I have a 8200 integrated nvidia chip that works well with vdpau with smplayer. I had issues with all flash 10.2 versions with the 260 and 270 series drivers.

The release version uses software rendering, but messes up vdpau (and xv in some cases) vsync nonetheless.

Edit:

The cfg thing worked, i have accelerated rendering, but i still have tearing in vdpau (that is solved after reboot, sometimes suspend/resume, until flash player initializes the first time).
