I am trying to setup a raspberry pi board as a piping device which could receive video from a camera or any other source and pipe it to the host pc. I am following the tutorial mentioned here
https://gist.github.com/justinschuldt/36469e2a89d95ef158a8c4df091e9cb4
I am able to successfully stream webcam video to the host pc. What I wanted to do was to use a video file instead of the stream from the webcam. In order to do that I did as follows
- Created a dummy v4l2loopback device
- Created uvc_gadget following the tutorial above
My setup looks like this
Afterwards I was able to start uvc_gadget as follows
Now when I tried to stream a video file to /dev/video2 I only got colored stripes on the host pc with the error no jpeg data found
On host PC
Error
I get almost similar behavior if I create a gadget using g_webcam instead of configFS.
Would be thankful for any help. I am assuming there are some issues with the encoding.
