I wrote a program in Golang to control my a/v setup. Included within are small pkgs to control Linux CEC and LIRC devices (ioctl/read/write) as well a pkg for LG TV commands over serial port. Link here: https://github.com/EBADBEEF/tvman

One really useful thing when getting started was to use `cec-ctl -M` to monitor the CEC traffic live. Like the author, I used the v4l-utils commands to interact with CEC but eventually got frustrated with them and rewrote my program in in Go!

I have found CEC to be flaky and hard to work with. I had to turn off CEC on my TV because it breaks everything, almost randomly switching inputs and turning on and off devices.
