classIf autoplay could start playback java.lang.StringIndexOutOfBoundsException: Index 41 out of bounds for length 30
// Under certain conditions there may be no-one holding references to // a media element from script, DOM parent, etc, but the element may still // fire meaningful events in the future so we can't destroy it yet: // 1) If the element is delaying the load event (or would be, if it were // in a document), then events up to loadeddata or error could be fired, // so we need to stay alive. // 2) If the element is not paused and playback has not ended, then // we will (or might) play, sending timeupdate and ended events and possibly // audio output, so we need to stay alive. // 3) if the element is seeking then we will fire seeking events and possibly // start playing afterward, so we need to stay alive. // 4) If autoplay could start playback in this element (if we got enough data), // then we need to stay alive. // 5) if the element is currently loading, not suspended, and its source is // not a MediaSource, then script might be waiting for progress events or a // 'stalled' or 'suspend' event, so we need to stay alive. // If we're already suspended then (all other conditions being met), // it's OK to just disappear without firing any more events, // since we have the freedom to remain suspended indefinitely. Note // that we could use this 'suspended' loophole to garbage-collect a suspended // element in case 4 even if it had 'autoplay' set, but we choose not to. // If someone throws away all references to a loading 'autoplay' element // sound should still eventually play. // 6) If the source is a MediaSource, most loading events will not fire unless // appendBuffer() is called on a SourceBuffer, in which case something is // already referencing the SourceBuffer, which keeps the associated media // element alive. Further, a MediaSource will never time out the resource // fetch, and so should not keep the media element alive if it is // unreferenced. A pending 'stalled' event keeps the media element alive. // // Media elements owned by inactive documents (i.e. documents not contained in // any document viewer) should never hold a self-reference because none of the // above conditions are allowed: the element will stop loading and playing // and never resume loading or playing unless its owner document changes to // an active document (which can only happen if there is an external reference // to the element). // Media elements with no owner doc should be able to hold a self-reference. // Something native must have created the element and may expect it to // stay alive to play.
// It's very important that any change in state which could change the value of // needSelfReference in AddRemoveSelfReference be followed by a call to // AddRemoveSelfReference before this element could die! // It's especially important if needSelfReference would change to 'true', // since if we neglect to add a self-reference, this element might be // garbage collected while there are still event listeners that should // receive events. If we neglect to remove the self-reference then the element // just lives longer than it needs to.
// Runnable for media element tasks. // These tasks have special behavior if the load algorithm is triggered before // the task is popped from the task queue, which is usually to skip running // the task.
