view output on streaming server

Can I stream outputs to remote server?
Hi, really cool stuff!
I am currently running pose_camera.py and I have a monitor connected to the coral via HDMI which is great for seeing the segments and key points being picked up by the model. Is it possible to send these outputs straight to a streaming server I could view in chrome? Would be great not to need an extra monitor for this.
I.e. I want to have pose_camera.py stream its outputs just like this demo: https://coral.ai/docs/dev-board/camera/#view-with-a-streaming-server, which I run by calling edgetpu_demo --stream

Hi, actually an update on this:
I'm trying to run the demos (https://coral.ai/docs/dev-board/camera/#view-on-a-monitor) that connect to a USB camera (since this is what I need), but running
edgetpu_classify \
--source /dev/video1:YUY2:800x600:24/1 \
--model ${DEMO_FILES}/mobilenet_v2_1.0_224_quant_edgetpu.tflite \
--labels ${DEMO_FILES}/imagenet_labels.txt
and also
edgetpu_classify \
--source /dev/video1:YUY2:800x600:15/1 \
--model ${DEMO_FILES}/mobilenet_v2_1.0_224_quant_edgetpu.tflite \
--labels ${DEMO_FILES}/imagenet_labels.txt
as well as
edgetpu_classify \
--source /dev/video1:YUY2:320x240:30/1 \
--model ${DEMO_FILES}/mobilenet_v2_1.0_224_quant_edgetpu.tflite \
--labels ${DEMO_FILES}/imagenet_labels.txt
I get the following error:
(edgetpu_classify:5606): Gdk-CRITICAL **: 01:01:58.888: gdk_monitor_get_scale_factor: assertion 'GDK_IS_MONITOR (monitor)' failed

I've tried doing sudo systemctl restart Weston but this hasn't helped.
Also, when I run the demo in https://coral.ai/docs/dev-board/get-started/#update-mendel step 7, as per the linked issue, I'm now getting this error:
mendel@arid-quill:~$ edgetpu_demo --stream
Press 'q' to quit.
Press 'n' to switch between models.

This is only fixed when I do a sudo reboot. But the demos with the camera don't work still :(
Sorry for the spam, but any help is really appreciated!!
And also, when I do v4l2-ctl --list-formats-ext --device /dev/video1 I get

Have you connected any monitor to the dev board? If not please try edgetpu_classify_server or edgetpu_detect_server commands to view the output on server as mentioned at: https://coral.ai/docs/dev-board/camera/#view-with-a-streaming-server
