Scales down the meshcast video output via the URL
&meshcastscaleparameter will scale down the Meshcast video output via the URL, post camera capture setup. Because of how Meshcast works, this is a sender-side parameter. You may wish to use this to lower the resolution if your camera has a fixed capture resolution.
Alternatively, if you need to dynamically adjust the resolution, that option already exists via camera settings via width/height slider adjustments.
