YouTube iframe API: Controlling Pre-existing iframe Players
The YouTube iframe API provides comprehensive functionality for controlling embedded videos. While the documentation typically focuses on adding new players to a page, it is also possible to manipulate existing iframe-based YouTube players.
Using the callPlayer Function
To control pre-existing iframe players, utilize the callPlayer function, authored by Rob W. This function allows you to invoke any supported YouTube player function.
callPlayer(frame_id, func, args);
Parameters:
Example Usage:
callPlayer("whateverID", "playVideo");
This code will play the video in the iframe with the ID "whateverID".
Ensuring Player Readiness
Before using callPlayer, ensure that the YouTube player is ready. If it is not yet ready, the function will queue the request until the player becomes available.
Listening for Player Events
The callPlayer function also supports listening for player events. To do so, pass "listening" as the func parameter.
callPlayer("whateverID", "listening");
This will establish a message event listener that will receive status updates from the YouTube player.
