[Request] obs-backgroundremoval

ngoonee · 2021-04-30 00:54:36

There's a relatively new OBS plugin for automatic background removal based on opencv's face detection. Removes the need for a physical greenscreen (theoretically). I'd like to try it but haven't found the time.

https://github.com/royshil/obs-backgrou … l/issues/8 is another Arch's user's try so far.

Instructions for building it by hand are available on the github and the author is actively responding to queries, but while there are reports on success in Debian I do not know if it is easy to do on Arch yet. If anyone would give this a go I'd be super grateful.

I think you first need a package for onnxruntime as https://aur.archlinux.org/packages/python-onnxruntime/ does not provide the c headers.

Good point. Haven't looked into that at all yet. Maybe during sem break.

Note the horrible seds.
Arch's obs-studio does not ship ObsPluginHelpers.cmake so that check is removed for now.
Include files for onnxruntime appear to be expected to all be in one directory unless the OS is APPLE that has one additional path onnxruntime/core/session which matches the package layout used by onnxruntime, with that path it then fails to find onnxruntime/core/providers/cpu/cpu_provider_factory.h. Also fails to find the generated header that has yet to be generated.

Very few changes from python-onnxruntime.
