Stream Display does not Initialize #2

Closed utcsox closed 5 years ago

utcsox commented 5 years ago

On coral-dev board, Mendel version 3 chef. Ran the following commands as instructed in the ReadMe

sh install_requirements.sh
python3 teachable.py --keyboard

Attached screen shot below, the expected behavior is that lines of FPS and class should stream, e.g. FPS 30.7; #examples: 0; Class One but in my case it appears to be frozen and the only output I see is when I press a key. I am also unable to quit with ctrl-c. I need to reboot the coral dev board. Any help or ideas would be appreciated. Thanks!

This is likely due to the fact that no camera is connected - I'm able to reproduce exactly this behavior only by disconnecting the camera. Check that your camera is connected and working:

for Coral Camera: v4l2-ctl --list-formats or for external USB camera: v4l2-ctl -d /dev/video1 --list-formats

should list a bunch of formats

Likewise, you can test the cameras by sudo apt-get install gstreamer1.0-tools gst-launch-1.0 v4l2src ! videoconvert ! autovideosink or gst-launch-1.0 v4l2src device=/dev/video1 ! videoconvert ! autovideosink

should display a window with the camera stream on the connected hdmi display.
