Virtual Camera support for AVfoundation

[jonatansnapir]

Hi Ramiro,

I've run into an issue trying to get OBS Virtual Camera detected as an input device for FFgac on MacOS. When I run -list_devices true in FFmpeg, I see the virtual camera and it functions fine, but with FFgac it doesn't show up in the list, and trying to force the input manually doesn't work. This problem doesn't exist on my Windows machine, where FFgac finds the virtual camera fine, so I believe it is related to the AVfoundation implementation of FFgac. Is this something that can be achieved using FFgac? If not, any idea how to work around this issue?

Best, Jonatan

Hi Jonatan,

Thank you for the report.

I don't have a mac to test anymore. Could you try building with the same configuration as the github builder https://github.com/ramiropolla/ffglitch-core/blob/ffedit-0.10/.github/workflows/macos-x86_64.yaml#L37 and see if it works?

I do --enable-avfoundation, but maybe it's not enough.

Hi Ramiro, thanks for the reply. I tried building ffgac following the github builder but no luck. Here's a screenshot showing the difference between results when listing the input devices for FFmpeg and for FFgac:

Seems odd to me that most of the devices appear in both but OBS does not. Maybe FFmpeg is including some library that OBS is relying on, that's missing from FFgac?

Thanks for your time,
Jonatan
