This CL adds support in RTCEAGLVideoView for rendering CVPixelBuffers as OpenGL ES textures directly, compared to the current code that first converts the CVPixelBuffers to I420, and then reuploads them as textures. This is only supported on iOS with the use of a CVOpenGLESTextureCache. The I420 rendering and native rendering are separated in two different implementations of a simple shader interface: @protocol Shader - (BOOL)drawFrame:(RTCVideoFrame*)frame; @end GL resources are allocated when the shader is instantiated and released when the shader is destroyed. RTCEAGLVideoView will lazily instantiate the necessary shader when it receives the first frame of that kind. This is primarily done to avoid allocating GL resources for both I420 and native rendering. Some other changes are: - Print GL shader compilation errors. - Remove updateTextureSizesForFrame() function. The textures will resize automatically anyway when the texture data is uploaded with glTexImage2D(). patch from issue 2154243002 at patchset 140001 (http://crrev.com/2154243002#ps140001) Continuing magjed@'s work since he is OOO this week.
