When using the qmlplayer2 example the colors of the Big Buck Bunny video are
not correct. 

Inside the VideoMaterialShader::updateState() function the m_id_rgbTexture var
is used to set the uniform value for RGB or YUV textures. If the video format
is GST_VIDEO_FORMAT_I420 the m_id_rgbTexture var is -1. Because of this the
uniform value for RGB textures is set. This causes the incorrect colors of the
video.

The attached patch solves this for me.
