Is it open source? I've been looking for a headless web recorder for a while, with audio support if possible.
Sadly no, it's like three different tools linked with the equivalent of bailing twine, one of which is a kiosk/home theater UI I wrote when I was just out of high school a really long time ago. Also it definitely wouldn't work headless.
I have seen headless browser recording tools before, not sure what framerate they could handle.
