[android-developers] Re: Camera + GLSurfaceView frame rate

Hi,

What camera preview frame rate are you using ? I think you might be able to adjust this between at least 2 values, 15fps & maybe 30fps options.

Are you converting YUV to JPG camera preview frames ? If yes you will need to try to make this conversion as efficient as possible for good fps.

Regards

I've set up a very minimal app that captures video frames from the camera and dumps them directly to a GLSurfaceView via a SurfaceTexture. This works fine but the frame rate is poor on both a Galaxy S3 and a Nexus 4. In the latter case I can't get better than about 10fps even when I don't do anything at all in my actual GL render callback.

I can post actual code but before I dig much further than this I'd just like to know if I should be able to get better frame rates than this or if this is the best I should expect. There are camera apps in the store like Camera 2 that are much smoother than this but maybe they're using the NDK + lower level APIs to achieve this?
