Screen Capture

If screen capture is supported and appropriate hardware is attached, the video output of the DUT can be captured. For the testbot, this requires a compatible video capture device to be connected that works with v4L2 and enumerates on the /dev/video0 interface. If that is the case, then capture can be started using the Worker class capture() method, for example:

Example

const Worker = this.require('common/worker');
const worker = new Worker('DEVICE_TYPE_SLUG', this.getLogger())
await worker.capture('start');

This will trigger video capture to start, and frames will be saved as jpg files in the /data/capture directory (which is a shared volume). Capture will continue until stopped with:

await worker.capture('stop');
