-34 is -ERANGE which generally gets raised if you request scaling that
your hardware (or driver) can't support.  Not all platforms are capable
of performing scaling and those that do support it generally have
limits.

You can also get an -ERANGE return if your coordinates could cause an
integer overflow (e.g., coordinates with values near INT_MAX).

Depends on the hardware/driver implementation. In general the driver
should fudge things enough that you'll get something reasonably close to
what you requested. For Intel hardware we support pixel accurate
coordinates (well, macropixel in the case of packed YUV 4:2:2).
Sub-pixel accuracy isn't supported on current hardware.

Help on drmModeSetPlane

2015-04-27 Thread Xie, William 
Hello, Syrjälä,
 For drmModeSetPlane API, regarding the ctrc width, height and src width and 
heitht,
Do they must 16 byte aligned?
For example, for the size of 33x66, will these value be supported?

William

Depends on the hardware once more. Also we don't have a proper API for it at 
this time. You may get lucky if you tell it to use a pixel format with alpha. 
But there's no guarantee what kind of blend equation you will get.

Also we don't really have an API for the plane Z order either. Some drivers 
have a property for that, but I don't think it's really well defined.

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.

Help on drmModeSetPlane

2015-04-15 Thread Xie, William 
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?

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
