No hardware rendering on Intel GMA X4500MHD (problem with switchable graphics systems?)

[Ede_123]

Hi all,

i have a problem regarding hardware rendering on my Intel GMA X4500MHD, e.g. on youtube. When watching a video on Youtube (e.g. http://www.youtube.com/watch?v=eI3f4b-b8ig) and displaying video information it says "software video rendering, accelerated video decoding". So hardware video decoding works, but hardware video rendering doesn't! Therefore playback is quite unsmooth an the video looks pixelated.

From what I read in an KB article my GPU should be capable of hardware rendering. It's also using the newest driver v8.15.10.2555.

But I think I have an idea whats the root of the Problem. I'm using a Lenovo T400 with switchable graphics. That means besides the Intel GMA X4500MHD the system also conains an ATI Radeon Mobility HD 3470. I assume Flash Player doesn't correctly recognize the special driver needed for switchable graphics to work and therefore disables hardware rendering?

I hope you can help me solve my problem? Or is it a bug that can only be fixed inside Flash Player and therefore needs to be adressed to developers?

Thanks,

Eduard

Hi Eduard,

Just posted in another thread of yours (for the ATI gpu).  Please try this in fullscreen mode to see what the video info overlay displays.  I suspect you'll get accelerated for both rendering and decoding.  This is actually a setting that YouTube has decided on, Flash Player supports both modes.

@ Chris:

Sorry, that doesn't change anything. With fullscreen mode you meant just clicking the fullscreen-button in youtube's mediaplayer?

Is there another site were I can test my flash-players playback capabilities besides youtube?

@ Pat:

Maybe, but I'm not using an Intel HD.

It's an Intel GMA X4500MHD, the integrated graphics card from the Intel GM 45 Express chipset, and for this card 8.15.10.2555 is the latest driver.

Sorry for that; you're right.

The only other page that comes to mind is the StageVideo demo located here: http://labs.adobe.com/technologies/flashplayer10/live-player/

It runs into network buffering issues, but I've found that toggling StageVideo/overlays on and off while viewing a task manager gives a good indication if hardware acceleration is working.

The latest driver version for Intel HD is 8.15.10.2622
