Plays a clip with an optional poster: tap to play inline, or full transport controls (the platform's own on iOS and Android, the kit's bar on the web), with boolean fit, autoplay, loop and muted props.

Give it a source (a { uri }, or a bundled asset from require), an optional poster shown until the clip's first frame is on screen, and the clip's aspectRatio (width over height, 16 / 9 by default): the frame fills its parent's width at that ratio and letterboxes the picture on black. Without controls it is an inline player: the whole picture is one play and pause control, a play emblem sits over the paused picture, and a spinner shows while the clip loads. With controls each platform shows transport its own way: iOS and Android hand the frame to their own player controls, and the web draws the kit's control bar under the picture, with play and pause, the elapsed time, a seek slider, the length, mute, and full screen.

autoplay starts a clip once it is ready unless the system asks to reduce motion; browsers autoplay only muted clips, and this site's own policy blocks autoplay, so the examples here play on tap. Name every clip with accessibilityLabel: its controls are announced as "Play", "Pause", "Seek" and "Mute" followed by that name. Playback runs through the optional expo-video peer; without it the frame keeps its size and poster in a labeled frame.
