WARNING: erroneous pipeline: no element "kvssink"

Describe the bug
I have made a near successful attempt to connect to launch live stream. I followed the given official guide of this repo and further of linux system. My OS is Windows 10 and with WSL2 I made a great effort to custom build a video-device supporting linux kernel. All worked. Project got complied successfully, path variables got loaded from the root of repo, and kvssink info got displayed. But upon executing above command, it failed.

I doubled checked the USB HD camera was attached using lsusb and it was. I also checked by running /dev/device* and there were two devices. Though strangely, upon running gst-device-monitor-1.0, it did not show up in the list; only the audio sources and sinks were present

This now begs the question, whether it is the camera which is incompatible or some other undocumented steps along the build process that I missed. The camera is not a webcam but a tiny one which runs with android-app and claims to work on PC

Another thing I did during debugging was I removed the last kvssink command from the above larger pipeline command, and it threw another error:

WARNING: erroneous pipeline: no element "video"

To Reproduce
Steps to reproduce the behavior:

1. In WSL2, follow the documentation
2. Using Usblib-win, attach usb camera to WSL2
3. Run the above command
4. See error

Expected behavior
Log or response from KVS telling video is streaming

SDK version number
I just cloned this repo and complied the project in a newly created build folder as directed in docs

Platform (please complete the following information):

• OS: Windows 10 with WSL2 (Ubuntu 22.04 w/ video-enabled kernel)
• Processor: Intel i5

Hi, can you confirm when you run gst-inspect-1.0 kvssink is it displaying info about kvssink or do you get a similar error?

[waleedshkt]

It displays info about kvssink
