Hi @yildizbilgin 

Did you ever try without the  "-a aac "--use-alsasrc" options? Was it working?

Thanks and Regards

HI @yildizbilgin 

I do not think the See3CAM_CU30_CHL_TC_BX has audio output. This is probably why this commnad is not working. The example is used with Logitech HD camera C920.

Try to get a camera with an audio output.

Regards

Hello,
Now I have changed the camera to Logitech Webcam.Now this is the screenshot of the errors.

sds.PNG

I use the instructions from https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18841937/Zynq+UltraScale+MPSoC+Ubuntu+part+2+-+Building+and+Running+the+Ubuntu+Desktop+From+Sources it is for zcu102 but i use it for zcu104 bsp file. I have copied the boot.bin and image.ub files to the sd card. 

What should i do to fix this error:

ERROR: from element /GstPipeline:pipeline0/GstAlsaSrc:alsasrc0: Could not get/set settings from/on resource.

> what is the camera model? Did you check that it has ALSA audio output?

I am talking about the instructions to "preparing linux images using petalinux" if you scroll down you can see it. I am telling you because I am not sure if i am doing the right thing. So I have needed the talk about the details. 

And yes this cam has an audio output.

> Ok. Then yes this is correct. Just take the BOOT.BIN + image.ub prebuilt in the ZCU104 BSP

And yes this cam has an audio output.

>Are you sure the format is ALSA?

Hello,

Can you just try below command without "-a aac "--use-alsasrc" options?

vcu-demo-camera-encode-file.sh

Best Regards.
