I tried crtc (0, 0, 3200, 1800) src (0, 0, 3200<<16, 1800<<16) but get a crash,
How can I enable scaling on overlay for video frame?

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?
William

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
