Use info and buffer to fill in the values of frame with the video frame information of frame
id.
When id is -1, the default frame is mapped. When id != -1, this function will return
false when there is no GstVideoMeta with that id.
All video planes of buffer will be mapped and the pointers will be set in frame->data.
