Matthew Waters	f8c6be86c2	glcolorbalance: return HARDWARE from get_balance_type	2017-12-09 19:32:15 +00:00
Matthew Waters	e3f53deb32	glcolorbalance: create the shader if it doesn't exist in the render callback ... Changing the properties may result in glcolorbalance moving from passthrough to non-passthrough and we weren't creating the shader in that case.	2017-12-09 19:32:15 +00:00
Matthew Waters	731f9928dd	gl: implement a colorbalance element ... It performs the exact same operation as videobalance but with opengl shaders and was tested with glvideomixer by comparing frames from videobalance and glcolorbalance.	2017-12-09 19:32:14 +00:00
