School Lobby Recognition Video: MediaCapabilities Decoding Checks Before Touchscreen Acceptance
Before accepting a school lobby athletic recognition touchscreen for deployment, run a school lobby recognition display MediaCapabilities decodingInfo test to confirm the device browser can decode the specific codec, bitrate, resolution, and framerate used in your recognition videos. The browser’s Web MediaCapabilities API returns three boolean values—supported, smooth, and powerEfficient—for each video configuration you supply. A supported: false result means the device cannot decode the format at all and the configuration must be rejected or replaced. smooth: true and powerEfficient: true indicate browser predictions of smooth, hardware-accelerated playback, but those predictions may initially be optimistic before local playback statistics have accumulated on that device. The API covers unencrypted file configurations only, and physical playback acceptance on the actual installed hardware remains a required separate step regardless of what the API returns.
