I recently purchased a 512MB Geforce 8400GS PCI card for an older AGP Athlon64 2.2GHZ Linhes 6.03 frontend. It works quite well with VDPAU for TV and Video playback at 1600x1050 - much better than my old AGP Geforce 5200 as far as the OSD not stuttering anymore, and now in beautiful color. Also, CPU utilization is about 10% of what it was with xVMC. Wonderful stuff really. No PIP or PBP any more though, they're currently not supported with VDPAU.

The problem isn't with mpg playback, or any other mythtv playback - it's with flash. Huludesktop is a slide show with this new PCI 8400GS, there's even some tearing - it's ugly. On another Linhes 6.03 frontend I use a Celeron 2.2GHZ PCIe motherboard with a 512MB PCIe 8400 and it runs very well - after about the first 10 seconds of slight stuttering it's picture perfect for as long as I keep it running.

Does anyone have better results with Huludesktop and the 8400 PCI card? Is it just the PCI bandwidth limitation coming back into play here? Maybe VDPAU isn't being activated in flash for this card? Does anyone know how to check that, or possibly force it if necessary? Your insight would be appreciated.

Both of these frontends are at the latest 6.03 iso + all available updates from the release repos. Both clean installs configured as identically as possible. I've tested this PCI 8400 on 3 different (all Athlon AGP) motherboards and pretty much the same dismal results, worse for the slower ones.

I have that version ant it runs fine with an Atom cpu. Are you using flash 10.1? That seemed to make things run smoother for me when I installed it.
VDPAU does not work with Flash, so that's not it. There is no way to use any video acceleration with Flash on Linux yet.

It might be the resolution is eating too much CPU? 1600x1050 seems like a lot of work for Flash to fill. Try another resolution and see if that is problem.

Thanks for the info uteck. Yes, I'm using 10.1. So your Atom uses a PCI 8400 and it works well with flash? Wow, what different results we have - is that a 330? This may show that the old AthlonXP processors are finally being left in the dust.

I've tried huludesktop at 640x480 and the PCI 8400 falls down flat. The AGP 5200 runs very well at that resolution, and almost acceptable at 1360*768 This is on the old AthlonXP 2500 class machine.

It's the 2.2GHZ Celeron w/ PCIe 8400GS that runs huludesktop at 1360*768. So I guess I'm not comparing apples to apples, just making some observations.

I haven't tried 1600*1050, that was an incorrect statement in my earlier post. I also don't think it would work well with these processors.

Sorry uteck, I see in your sig that your processor is a 330. I'll keep playing with this PCI 8400GS to see if I can get Huludesktop working better with it - I'll try the various beta flash versions Adobe has released and report back here. Maybe it's my 8400 - It's a new ECS N8400GS2 - 512MB ddr2, dsub, dvi and s-video - that all looks fine to me

I'm not giving up on these old Athlons yet! If the AGP FX5200 works with flash (albeit a bit slowly), why wouldn't a PCI 8400GS work just as well?

OK, I'm giving up on my old Athlons. :( I can get Huludesktop to work on them, but it's sluggish at best, and completely useless in other cases. The older platform just can't keep up with Flash. I'm talking about both the Thoroughbred and Barton cores up to the 2500+ - I haven't tried any faster versions, and don't plan on it.

On a more positive note - some modern day processors are very affordable and you can build a real nice LinHES box for less than you may think...

I'm sure it's a PCI bandwidth problem. PCI is not fast enough for non-accelerated flash playback, no matter what CPU you have. PCI-e is fast enough.

uteck must be thinking PCIe. uteck?

Well, I looked up the D945GCLF2 motherboard and it does have PCI slot. So perhaps uteck is using a PCI graphics card, in which case I defer to his actual experience with it.

Sorry to confuse things.

Flash 10.2 support acceleration w/ nVidia chipsets that support VDPAU. I have this compiled for R7 and will take a crack at compiling it for R6 later today or tomorrow.

Flash 10.2 is now in the repo.
Code:
sudo pacman -Sy flashplugin

After installing that the version shows up as 10.0.r15 which doesn't seem right.

How are you getting that version number? From flash itself?

In Firefox:

Tools -> Add-ons -> Plugins

or using:

about:plugins

or using:

https://www.mozilla.com/en-US/plugincheck/

All of which should be getting the version form the plugin itself.

FWIW - I manually upgraded the browser to 3.6.13 and the latest flashplayer sometime back. I don't remember if the older version of browser has that "Add-ons" entry in the menu, but either URL should work.

The latest flashplayer release for Linux (10.2.152.27 IIRC), which is supposed to include hardware acceleration for cards that support VDPAU, doesn't seem to do so well with older video chips.

The problem I've seen so far appear when going to full screen (1920x1080) on the HDTV with the old FX5200 based card. With hardware acceleration enabled it plays smoothly for some things, but others just go to a blank black screen. With it disabled the image tears and stripes horizontally, especially during any sequence with a lot of motion or other picture changes. I'm not sure which is worse.

This was working beautifully with 10.1.102.65 before my recent update. If you run into this problem and didn't think to save the older version, Adobe has an archive of older versions for flash developers who need to test against both old and new releases. I'm about to take advantage of it to downgrade the version on my machine...

Caveat Utor!
