NvFBC support question #171

Open jorgefm opened 3 years ago

jorgefm commented 3 years ago

Hi, I would like to know if the NvFBC NVIDIA extension to capture desktop is a possibility to be added to x11vnc? I've implemented a test concept using this API to grab the frames from an OpenGL application running in a NVIDIA cards and the artifacts I get when I use other APIs, like XGetImage, to grab the frames disappear. With x11vnc I get the same XGetImage's artifacts. The NvFBC functionality is already present in your system if you're using the proprietary NVIDIA driver, in the libnvidia-fbc.so library. Thanks!

That could be a possibility, but vendor-specific extensions sound like a niche use case. If you can come up with something more generic, the possibility of inclusion is much higher.

The generic way is how it's already implemented but you get artifacts grabbing frames from a host running an OpenGL app under a NVIDIA card, which niche is so wide :)
