I have followed both the guided installation and manual installation of the remotv controller on a Raspberry Pi and was able to control a robot successfully. I am now trying to get the remotv controller to run on a BeagleBone Blue which has not been successful. When I run the controller.py program, remo.tv says the robot is online and only streams audio while the video stays black. I have checked that the webcam does show up on /dev/video0 which is also what I have set in my controller.conf file. When I run the program I get this output:
debian@beaglebone:~/remotv$ python controller.py 
04:48:27 - controller.py : RemoTV Controller Starting up
modprobe: FATAL: Module bcm2835_wdt not found in directory /lib/modules/4.14.71-ti-r80
aplay: main:788: audio open error: No such file or directory
04:48:29 - controller.py : RemoTV Controller Started
04:48:29 - controller.py : Unknown event type

Video does not stream but audio does.
Also as a comparison, I connected to remo.tv using a raspberry pian and had success str
