 ### Make
 The most convenient process is to clone the µStreamer Git repository onto your system. If you don't have Git installed and don't want to install it either, you can download and unzip the sources from GitHub using `wget https://github.com/pikvm/ustreamer/archive/refs/heads/master.zip`.

 :exclamation: If you get a poor framerate, it could be that the camera is switched to photo mode, which produces a low framerate (but a higher quality picture). This is because `bcm2835-v4l2` switches to photo mode at resolutions higher than `1280x720`. To work around this, pass the `max_video_width` and `max_video_height` module parameters like so:

-```bash
