This feature is in development and is not yet released. It will be included in the next point releases of Avalon versions 5 and 6. |
Avalon Media System provides a simple API interface to allow cross-domain control of a media player embedded in an iframe.
Using this API, client webpages will be able to perform this limited set of operations on the player:
- Play
- Pause
- Get Current Time (in seconds)
- Set Current Time (in seconds)
- Toggle auto-replay (loop)
Play, pause, and toggle auto-replay are sent without parameters: postMessage({'command':'play'})
SetCurrentTime is sent with params: postMessage({'command':'set_offset','offset':123})
GetCurrentTime is sent with no parameters, but requires that a listener be available to hear the server's response, which will look like: data:{'command':'currentTime','currentTime':123}
