Dokumentacja

Kluczowe właściwości i metody

Składniki, po które sięgasz najczęściej.

Source

Src sets the media URL and MediaType (TsgcHTMLMediaType: mtVideo, mtAudio) chooses the element rendered.

Playback

Controls, Autoplay, Loop and Muted map directly to the HTML5 media attributes.

Sizing

Width and Height set the player dimensions; Responsive wraps a video in a 16:9 responsive ratio container.

Poster

Poster shows a placeholder frame before a video plays; VideoID sets the DOM id.

YouTube

BuildYouTube(aVideoID, aWidth, aHeight) returns a responsive YouTube iframe embed in a single static call.

One-line build

Build(aSrc, aMediaType, aControls) returns the player HTML in a single static call; HTML renders a configured instance.
