// that generate test output frames.
// By default, the factory has one device outputting I420 with
// USE_DEVICE_INTERNAL_BUFFERS. It supports a default set of resolutions.
// When a resolution is requested that is not part of the default set, it snaps
// to the resolution with the next larger width. It supports all frame rates
// within a default allowed range.
