<![CDATA[Running inference on a gstream with tflite]]>Hello, I was wondering if any one knows a way to pipe a video stream from gstream into the tflite server so I can run inference on it. I am currently running the commands:

gst-launch-1.0 v4l2src device=/dev/video2 ! "video/x-raw, width=1920,height=1080" ! videoconvert ! video/x-raw,format=YUY2 ! videoconvert ! x264enc ! rtph264pay ! udpsink host=192.168.0.149 port=8554

on the voxl2 and

gst-launch-1.0 udpsrc port=8554 ! "application/x-rtp, payload=127" ! rtph264depay ! avdec_h264 ! videoconvert ! xvimagesink

on my host machine which gives me a video stream.

Ideally I would just use the uvc server but I dont believe the uvc server supports the camera I am using. Is there a way to make a pipe out of the stream to then be the source for the tflite server? Or preferably a way to get it working with the uvc server?

For reference I am using a Sony FCB-ER8530/J 20x 4K CMOS Block Camera. Running voxl-uvc-server -l gives me

It may take some slight tweaking to get voxl-uvc-server to support your specific camera
