Hello,
xvimagesink has hue/saturation/brightness/contrast properties. gst-inspect says the default value for these is 0. however when i set them all to 0, the color and brightness/contrast look really off. is there a reason for this? Time for vacation? WIN what you need.

The actual default is "whatever the current values on the actual Xv
port are", which isn't determinable until we open the device - which gst-inspect does. Additionally, you probably shouldn't ever do anything with these values, and just pretend they're there for backwards compatibility.

Hi Michael,
So I can't control the contrast/brightness/hue/saturation in my application that uses gstreamer? > Date: Thu, 31 Jul 2008 17:11:44 -0700 > From: [hidden email] > To: [hidden email] > Subject: Re: [gst-devel] xvimagesink > > The actual default is "whatever the current values on the actual Xv > port are", which isn't determinable until we open the device - which > gst-inspect does. > > Additionally, you probably shouldn't ever do anything with these > values, and just pretend they're there for backwards compatibility. > > Mike > > > On Thu, Jul 31, 2008 at 4:48 PM, Ash <[hidden email]> wrote: > > Hello, > > xvimagesink has hue/saturation/brightness/contrast properties. gst-inspect > > says the default value for these is 0. however when i set them all to 0, the > > color and brightness/contrast look really off. is there a reason for this? > > ------------------------------------------------------------------------- > This SF.Net email is sponsored by the Moblin Your Move Developer's challenge > Build the coolest Linux based applications with Moblin SDK & win great prizes > Grand prize is a trip for two to an Open Source event anywhere in the world > http://moblin-contest.org/redirect.php?banner_id=100&url=/ > _______________________________________________ > gstreamer-devel mailing list > [hidden email] > https://lists.sourceforge.net/lists/listinfo/gstreamer-devel With Windows Live for mobile, your contacts travel with you.

I'm just suggesting that you shouldn't; it's not a useful feature on modern hardware.

In reply to this post by michael smith-6-3
I guess my question is, lets say I started playback of video and I query the hue, saturation, contrast, brightness elements from xvimagesink. They all read as 0, and video playback looks normal. However right after, if I set each of them to 0, the video playback looks like it has too much brightness and color. I know you said to use these properties only for backwards compatibility, but is this a bug of some sort?
