I'm looking into the h264encode.c example where the VAConfigAttribEncMaxRefFrames attribute is used to retrieve the number
of maximum reference frames. When this attribute is supported the value is not checked against the num_ref_frames variable. What happens if num_ref_frames is larger than the value in the VAConfigAttribEncMaxRefFrames attribute? The num_ref_frames is used in the SPS.
