We are using ti8148 based board and we are using the ADV7180 video decoder, problem in capturing the image.

Are you using EZSDK?

yes we are using EZSDK.

Thanks,

Hi,
We are using the EZSDK on ti8148 evm board and using omx_camera element we have captured images as well. but we are facing the problem in the costumed board in which we are using ti8148 processor and adv7180.

below are the logs when we are running the gst scripts.

Please let me know gst scripts for debugging, I will reply with the response log.




Thanks,

Hi,
Command :
gst-launch -e omx_camera ! "video/x-raw-yuv, format=(fourcc)

Are you interrupt it here?

I have added but there is no extra prints except as shown below

Yes we are interrupting giving some 5 minutes time.

Hello,

In the gst-debug log there is nothing which could point where is the problem. Per the log all the element's srcs and sinks are connected and the elements are moved to the PLAYING STATE.

Have you verify it for example with saLoopBackFbdev demo is it working?

Have you try it to use v4l2src instead of omx_camera, since in the default EZSDK we does not have such element?

Best Regards,
Margarita

Hi,
We have tried saLoopBack demo but it is blocking on vidic_dequebuf.

Hi,
I have a doubt, What will be the response if clock, vsync, hsync are coming to the processor and data through data lines is not reaching to the processor?

Hi Margarita,
Once after conforming that the video codec lines to the processor we have cleaned the build, compiled and tied capturing the video, it was working but it was showing three video images displaying one below the other when we are playing the captured video.


Thanks,
Sudheer.
