◆ Check16BitFBO()

void MythRenderOpenGL::Check16BitFBO ( void )

protected

Check for 16bit framebufferobject support.

We don't restrict this test based on OpenGL type or version to try and give as much support as possible. It will likely fail on all GL/ES 2.X versions.

Note: Qt support for 16bit framebuffers is broken until Qt5.12 on OpenGL ES3.X.; Qt only supports GL_RGBA16, GL_RGB16, GL_RGB10_A2 and GL_RGB10 but we only test for RGBA16 as it should be widely supported and will not restrict the use of alpha blending.
