[Intel-gfx] Can't not play video larger that 2048x2048 using xv

[Kevin Liao]

Hi all,

I want to play a video (3648x2752) through mplayer and xv using the
following command:

./mplayer -vo xv -nosound -geometry 912x688 test1.avi

But mplayer just failed with the error message as below:

VO: [xv] 3648x2752 => 3648x2752 Planar YV12
Source image dimensions are too high: 3648x2752 (maximum is 2048x2048)
FATAL: Cannot initialize video driver.

Then I try to modify the intel_video.c by changing both IMAGE_MAX_WIDTH
and IMAGE_MAX_HEIGHT to 4096. After that, mplayer seems to work but the
screen is always black. If I use gl as video output, everything works
fine. Here are some information of my system:

Hardware: Sandy bridge
Kernel: 2.6.37.6
Intel driver: 2.14.0
X server: 1.9.5
VGA resolution: 1920x1200

Is it possible that the video larger than 2048x2048 can be displayed by
xv? Thanks a lot for any help.

Regards,
Kevin Liao
