Hi all,

 

I am trying to run the DVSDK demo for dm6446 in davinci EVM kit. 

DVSDK 1.3. According to the DVSDK 1.3 release notes, I downloaded the
mentioned kernel or LSP.

Its mvl_4_0_1_demo_lsp_setuplinux_01_20_00_014.bin

Also the demo version, dvsdk_1_30_01_41.bin

I was ablt to build the demo and kernel, but couldn't run.

 

The error was with video driver and v4l 

 

ERROR while running :

Encodedecode demo started.

Encodedecode Error: Failed to get the requested screen size: 720x480 at
16 bpp

Encodedecode Error: Failed ioctl FBIOPUT_VSCREENINFO on /dev/fb/0

Capturing 720x480 video (cropped to 720x480)

 

Total I-frames: 0, P-frames: 0, B-frames: 0, IDR-frames: 0 rejected: 0

 

 

And the application terminated.

 Am using NTSC(720x480) camera and NTSC LCD monitor.

While debugging I found the following. 

var->xres = 720

var->yres = 480

var->xres_virtual = 720

var->bits_per_pixel = 16

var->yres_virtual = 960

line_length= 1440

fb_size = 691200

 

and its failing when they check var->yres_virtual * line_length <=
fb_size in window_will_fit_framebuffer?

 

Can anybody infer what is going wrong? What could be the mistake?

According to DVSDK 1.3 release notes, the demo should run without any
more steps.

 

Regards,

Naveena
