HD4600 no youtube video hardware decoding.

[hackindom]

My built i5 4760 + H87m-D3h, installed 10.9.2, Chameleon boot loader. Almost everything works fine. But When I check the HD video on youtube, I only got the accelerated video vendering, but software decoding.( which is supposed to be accelerated video decoding as well.)

I have an old MBP, which has 9600m on board, and it does hardware acceleration for the video decoding stuff. I believe that HD4600 should be able to hardwarely decode the HD video stuff. So any one can help me get the one last issue solved? Thanks.

Or Do I have to ad an dedicated Graphic Card, that would be possible to enable full video acceleration?

I have this problem too. Using Chimera with basic options and IGPEnabler

Power management is not implemented correctly. See: http://www.tonymacx86.com/mavericks...vericks-native-cpu-igpu-power-management.html

I fixed the power management with ssdt and imac profile.

Intel Power Gadget:


XCPM Mode in Terminal:


AICPMInfo Power states:








And still shows software video decoding

On real macs, video decoding works fine

It works on my Lenovo u430 (HD4400 mobile). Do you have the latest flash player from Adobe installed?

FYI: You're lacking IGPU PM. Requires DSDT/SSDT patching...

Latest flash installed (14.0.0.125):



Chrome:



Safari:






I believe other people are also having this problem (The OP, me and this ****** user - http://www.******.com/r/hackintosh/comments/27ufz2/haswell_hackintosh_with_hd4600_gpu_no_youtube_hw/ )


I tried using clover and got the same result but I'm not an expert at all. Perhaps some framebuffer patching or something is required? Please let me know if there's anything else I can try. Hardware acceleration in browser Firefox is also absent.


I appreciate your time. Thank you.
