I love jamming over a backing track or song. Record it. Listen back, Improve. But using your webcam, the QC USB stereo channel and the playing track at the same time, well, I had no solution for that.
So I’m building it myself (programming in C) and I call it QJams. I’m testing it a dozens of times a day now and I expect you guys are going to love it. Or not 
Caveat: This is a Linux only program. Currently depends somewhat on my own distro (CachyOS/Plasma) but when I release this it should be distro independent. Don’t hold your breath, this is not going to be ready tomorrow. I’ve been working on this for about a week now and although the basics are in there are bugs, missing features, etc. etc. Will update progress when I have progress.
