No hardware video decoding on ATI Mobility Radeon HD 3470

Hi all,

does anybody know why accelerated video decoding isn't avaiable on ATI Mobility Radeon HD 3xxx Series? From what I read in the corresponding KB article it works on the desktop counterparts that are based on the same hardware.

In my case I'm using an ATI Mobility Radeon HD 3470 on a T400 with switchable graphics (same as reported in this thread). When watching a video on Youtube (e.g. http://www.youtube.com/watch?v=eI3f4b-b8ig) and displaying video information it says "accelerated video rendering, software video decoding". So hardware video rendering works, but hardware video decoding doesn't! It's acceptable on my machine since it's equipped with a decent fast Intel P8400 CPU, but since my graphics card supports hardware decoding for h264 video it's just a waste of ressources.

Does anybody know if Adobe plans support forhardware decoding with these graphics cards? Or is there even a way to use hardware decoding although not fully supported?

Thanks

Eduard

Could you try viewing the same video in fullscreen, then check the video information again?

Sorry, also for ATI, fullcreen mode doesn't change anything.

Same thing here, software video decoding with a nVidia GTX580 - i7930 - W7x64, Flash 11.3.31.222, how can we fix this?

Thanks

If you read in graphics hardware support in some previous releases of Flash Player, flash video decoding support a.k.a. h.264 hardware video decoding is supported fully by ATi(or AMD) Radeon HD 4xxx and higher. The Radeon HD 3xxx and lower can't support h.264 video decoding for flash video decoding fully enough.
