Oh, I tried it on BDW. So we need to use other way to scale the video to full screen?
Yes, unfortunately.

To make it more specific,
For example: 1: video frame size is 1280x720, 2: screen resolution is 3200x1800,
How can I set crtc and src parameters?
1: crtc (0, 0, 3200, 1800) src (0, 0, 3200<<16, 1800<<16) 2: crtc (0, 0, 3200, 1800) src (0, 0, 1280<<16, 720<<16)
Which one is correct?
2 is correct.
What hardware are you trying this on? Do note that on HSW/BDW/VLV/CHV the hardware lost the plane scaling ability. It's coming back on SKL.

Question please, could someone share the meaning of the parameters for drmModeSetPlane in libdrm?
int drmModeSetPlane(int fd, uint32_t plane_id, uint32_t crtc_id, uint32_t fb_id, uint32_t flags, int32_t crtc_x, int32_t crtc_y, uint32_t crtc_w, uint32_t crtc_h, uint32_t src_x, uint32_t src_y, uint32_t src_w, uint32_t src_h)
My problem is, whatever value I set, the video is not full screen mode, Anything I missed?
Thanks William
