Limiting FPS for external webcams

[baklbakl]

Is there any way to limit the FPS a pipeline runs at when using an external webcam? I'm using the April Tag plugin and I want to prevent it from using too much CPU. I know I can turn down the number of threads it uses, but I want frames to be processed quickly when they are received, so I don't want to turn down the number of threads. Currently I have my webcam running at 720p with YUY2 (uncompressed) so it runs at 10 FPS, but I'd like to be able to run it a 360p and 10 FPS. I see that OpenCvInternalCamera2 has support for this, but I think this is only for internal cameras and not webcams.

Thanks!

This is not currently supported, though PR #75 which I honestly forgot about until now attempts to implement this.
