I have tried searching this forum for no avail.
Trying to brighten up the video playing on my Boxee (running on MiniMac)
I could not find any controls for changing the video brightness.
Is there a way to do that?

unfortunately no.
it is available in the infrastructure but was "hidden" for various reasons.
we definitely should consider restating it.

thanks.

any way for me to enable it? or any version coming soon that will have it?

any cheat-code that enables it? :) :)

well - if you are compiling from source you can comment out some lines in GUIDialogVideoSettings.cpp. specifically - the tests for "g_renderManager.SupportsBrightness()" and "g_renderManager.SupportsContrast()" (around line 95).

I could be misunderstanding the question, but, I have these opetions and they are fully functional.

While watching a video > Settings > Video > Brightness/Contrast.

Are they just missing on OS X?

actually - it depends on the gfx card and its capabilities.
i also think the check has a bug so those options may not appear sometimes even though the gfx card can handle it.

Vulkan, the X3100 (MacBook and MacBook Air) and GMA 950 (Mac Mini) support OpenGL 1.2 in OS X, without the ARB Imaging extension that is needed to perform the brightness and contrast operations. It is however supported on nVidia and ATI hardware on OS X (MacBook Pro and iMac).

Maybe this is why it doesn't show up in Boxee sometimes?

hi d4rk. thanks.
but when i test on my macbook - if i disable the check for glewIsSupported("GL_ARB_imaging") then brightness *does* work. i mean the check returns false so the control is hidden but if i hard wire it to show up - it actually does work.
weird.

Interesting Vulkan, is yours a MacBook or a MacBook Pro and what GPU is it?

@ronkass, video calibration 101; never touch the brightness/contrast/gamma on the source device (whether that source device is a computer with Boxee or a stand-alone DVD-player, etc.), you should only ever use the brightness/contrast/gamma settings on your display (TV) to calibrate them.

I highly recommend you buying DVE (Digital Video Essentials) or Avia DVD:

Hey Tom, awesome avatar :-) . Sucks about the MBP though. Will investigate some more regarding the X3100, thanks.
