RGB Encoding

This example shows how to configure the depthai video encoder in h.265 format to encode the RGB camera input at 8MP/4K/2160p (3840x2160) at 30FPS (the maximum possible encoding resolultion possible for the encoder, higher frame-rates are possible at lower resolutions, like 1440p at 60FPS), and transfers the encoded video over XLINK to the host, saving it to disk as a video file.Pressing Ctrl+C will stop the recording and then convert it using ffmpeg into an mp4 to make it playable. Note that ffmpeg will need to be installed and runnable for the conversion to mp4 to succeed.Be careful, this example saves encoded video to your host storage. So if you leave it running, you could fill up your storage on your host.
