Hi,
I am trying demo omapdrmtest on my android device(based on 6am1.2).
command: ./dmabuftest -s 32:1920x1080 -d /dev/video0 -c 1568x1080@NV12
1920x1080 is my lcd panel resolution.
1568x1080 is my camera resolution.
something error please refer to attechment.
Q:
1.
static int
post_vid_buffer(struct display *disp, struct buffer *buf,
uint32_t x, uint32_t y, uint32_t w, uint32_t h) //util/display-kms.c
what is the third params 'buf' is represent of? or, if I write directly one frame to a file, which buf or poiner I can use?
2. my test failed on drmModeSetPlane call,
failed log: "ERROR:post_vid_buffer:447: failed to enable plane 37: Permission denied"
this error will appear if framebuffer is in use? how to fix it?
Regards,
Sinkeu
