Video Controls

Description

Basic video playback controls to play/pause, seek and maybe even switch audio or texttracks would be nice to have. In addition, we can think about adding controls to manually select a video/audio quality if ABR streaming is used.

The basic video controls would be controlling a media pipeline instance, for MPEG_media definitions in the gltf source, where MPEG_media.controls == true, the video controls should be enabled.

• A scene may have multiple medias playing concurrently, with individual media controls.
• Controls such as play/seek/pause/resume may be applied to multiple media pipelines at once where MPEG_media.unifiedTimeline == true.

Did you also consider a top level Play/Pause/Seek/Buffering scene playback control ?
