Video Decode Acceleration on Fermi/... GPUs ?

23 March 2013 - 11:01 AM

Video Decode Acceleration is not working for me an many others with Nvidia GPUS. I wonder if its possible to get it working with some binpatching.

Things I noticed so far:
  • AppleVAFramework request an higher/other GPU Power state
    AVF error: AVAHDGPURendererVP2VP3BoostVP3: AGPMSetBoost code = 0 returned 0xe00002c2 (ig)
    
    this error can be hidden by using MacPro 3,1 SMBIOS (completley disables AGPM/VDA)or adding BoostPState to AGPM info.plistbut this is causing safri to crash often
  • when using VDADecodeCheck
    AVF info: Successfully connected to the Intel plugin, offline Gen6
    
    intel quick sync enables  AirPlay Mirroring but VDA is not possible together with a dedicated GPU for me (with HD4000 this is may different)
  • when disabling iGPU in bios and using iMac12,2 SMBIOS and unloading all INTELHD kexts and efi/dsdt info
    AVF info: Successfully connected to the Intel plugin, offline Gen6
    
    is still present.
The question is what enables VDA: device-id, subsystem-id, GPU name, Architectureand can we patch it like OpenCL?
