I know, was just trying first with xcode project defaults, had to fix some compilation errors, and then tested a bit.
I was thinking OpenGL/hardware video decoding wouldn't use that much CPU, more GPU.

Just built in release (-O3) CPU dropped, to 50% in idle, 120% during play. framerate is improved, but still choppy and hardly watchable.
I hope I did something wrong Smile

"had to fix some compilation errors", what errors ?

also xbmc.log will show if vtb is being used or not.

Had to change this

Code:

Also changed code signing settings to use some profile, was too lazy to search for how to bypass apple signing, last time I did it took hours patching some Xcode binaries... Wink

VTB... hmm no idea of what it is... searching... SD renders fine at 40% CPU.

EDIT:
VideoToolBoxDecoder maybe? :

EDIT2: Read some forums threads, I've basically followed README.ios instructions and (dumbly since there is no instructions about this in readme) hit run&build in Xcode.
So I guess I'm running it under mobile user and from what I've read it is probably sandboxed = not using VTB.

**davilla** · 2012-05-27 04:33

VTB == VideoToolBox, it's how we do video hardware decode.

**davilla** · 2012-05-27 04:41

if you are running under xcode, then it's an xcode sandbox and that prevents vtb.

carbncl · 2012-05-27 04:52

Yup that's was definitely my issue, thanks for pointing me to the right direction
Fixed this and now works perfectly @73% CPU, perfect framerate, amazing in retina Smile

Thanks again, maybe adding a small line at the end of README.ios stating this would prevent noobs like me to do this mistake Wink

**davilla** · 2012-05-27 05:12

"Fixed this", explain please.

carbncl · 2012-05-27 05:15

As suggested, just moved the .app outside its sandbox to /Applications, so it now use VTB properly.

xamphear · 2012-05-27 05:25

Is there a .deb file of your build available for those of us without the sdk and/or a mac to build it on?

can xbmc play 1080p on iPad3/ATV2 v2 with VTB?
