# libcamlite-rs-test

Test out basic functionality of libcamlite-rs

This shows that in a few lines, one can begin writing rust apps that make use of both the h264 and rgb streams.  Its about as simple as:

    let libcam = LibCamClient::new();

    let lowres = StreamParams{ width: 300, height: 300, format: StreamFormat::STREAM_FORMAT_RGB, framerate: 30};

    libcam.client.setupLowres(&lowres);

    let h264Params = StreamParams{ width: 1920, height: 1080, format:  StreamFormat::STREAM_FORMAT_H264, framerate: 30};

    libcam.client.setupH264(&h264Params, 5, &"main".to_owned(), &"2mbps".to_owned());

    let mycb = Box::new(MyCallback::new(lowres));

    libcam.setCallbacks(mycb);

    libcam.run();

You should then see output like the following:

    low: 31 calls in past 1.0325267 seconds; 30.023436 calls/sec

    h264: 31 calls in past 1.0341291 seconds; 29.976913 calls/sec

    Wrote output.ppm

    low: 31 calls in past 1.0325396 seconds; 30.023062 calls/sec

    h264: 30 calls in past 1.0032188 seconds; 29.903748 calls/sec

All in this takes up about 70MB of ram and a load average of 0.5 on a raspberry pi zero 2w, running bullseye aarch64! 

You can view the output.h264 file in VLC.  The PPM should be viewable in any image viewer.
