v4l2src capture problem

Grettings,

I am trying to let v4l2 capture working on my evm814x board from mistral. The EZSDK I am using is Version5_03_01_15.

My bootargs are:

bootargs=console=ttyO0,115200n8 rootwait rw mem=256M earlyprintk notifyk.vpssm3_sva=0xBF900000 vram=50M ti814xfb.vram=0:16M,1:16M,2:6M root=/dev/nfs nfsroot=10.0.1.27:/root/targetfs ip=dhcp
autoload=no

What I modified is following:

1.Copy load-hd-v4l2-firmware.sh to /etc/init.d

2.Add S01load-hd-v4l2-firmware.sh into /etc/rc3.d and /etc/rc5.d

3.Change S01load-hd-firmware.sh to K01load-hd-firmware.sh

And I run the lsmod, got this. So I assume my change is okay, right?

root@dm814x-evm:~# lsmod

===================================================================================================

Then I run the saloopback demo and get following info:

root@dm814x-evm:~/dm814x-evm/usr/share/ti/sa-examples/video/bin# ./saLoopBack
VPSS_GRPX : please stop grpx0 before continue.
Driver Name: ti81xxvin
Driver bus info: TI81xx Platform
Driver is capable of doing capture
saLoopBack:
Mode set is 0
Setting DV Preset failed

Why the DV preset fialed here?

===============================================================================================================

After doing all these above, I reboot the board, and everything is okay until I try to run a gstreamer pipeline with v4l2src element.

gst-launch -v v4l2src ! omx_ctrl display-mode=OMX_DC_MODE_1080P_30 ! omx_videosink sync=false
gst-launch -v v4l2src always_copy=FALSE ! 'video/x-raw-yuv,width=1920,height=1080' ! fakesink

gst-launch -v v4l2src ! fakesink

None of them worked and all gave me the following error messages:

Could some one help me or point out what I am missing here.

Setting pipeline to PAUSED ...

Hi,

It seems like display is set for 800X480 resolution. Are you running this without any changes to any driver/application.Can you check resolution of each display by following command.

"cat /sys/devices/platform/vpss/displayx/mode". I think one of the display will show 800X480 mode. May be display 2. Are you trying to run this on DM8148 with LCD on it.?

Change mode to 1080P60 on all displays using following command

"echo 1080p-60 /sys/devices/platform/vpss/display1/mode"

Regards,

Hardik Shah

Hi Hardik,

Thanks for you quick reply and yes my problem was exactly as you said.

Now my board can run the v4l2 demos.

Hi,

Good to know problem is resolved. By default resolution for all venc is set to 1080p-60 once you load vpss.ko. So any idea which component is changing that resolution to 800X480?

Regards,

Hardik Shah

Hi Hardik,

I donot know why, the default resolution of my LCD on EVM was 480p, before I run anything.

So, I have to reset it to 1080p to run the demos.

Regards,

Jun

Hi,

No problem. May be because LCD is of that resolution.

Hi, Jun_Zhang

I encountered the same problem:"Setting DV Preset failed". You said you found an error on your setup. I would like to know what is the error?

Thanks.

Hello Margarita,

I have fixed the problem. At first, I did not set the video input with the correct refresh frequency. When I changed the refresh frequency to 1080P60, It works fine.

Thanks.
