队列加载失败，并显示“传入的queueData不完全有效”

问题描述

花了很长时间才能达到这一点。我有一个测试用例，其中队列加载因此错误而失败。我不知道为什么会这样过去。该API的文献资料很少。

“ cast_receiver_framework.js：114 [3.144s] [cast.receiver.MediaQueue]传入的queueData并非完全有效：[object Object]”

https://dev.electroteque.org/chromecast/

function addItem(index) {
             var mediaInfo = new chrome.cast.media.MediaInfo(
            mediaContents[index]['sources'][0],'video/mp4');

            mediaInfo.Metadata = new chrome.cast.media.GenericmediaMetadata();
            mediaInfo.Metadata.MetadataType = chrome.cast.media.MetadataType.GENERIC;
            mediaInfo.Metadata.title = mediaContents[index]['title'];
            mediaInfo.Metadata.images = [
                {'url': MEDIA_SOURCE_ROOT + mediaContents[index]['thumb']}];

            return mediaInfo;
        }           

     /*   var request = new chrome.cast.media.LoadRequest(mediaInfo);
        castSession.loadMedia(request).then(
            this.playerHandler.loaded.bind(this.playerHandler),function (errorCode) {
                this.playerState = PLAYER_STATE.ERROR;
                console.log('Remote media load error: ' +
                    CastPlayer.getErrorMessage(errorCode));
            }.bind(this));*/

        const queueItems = [
            new chrome.cast.media.QueueItem(addItem(0)),new chrome.cast.media.QueueItem(addItem(1))
        ];

        console.log("items",queueItems);

        const request = new chrome.cast.media.QueueLoadRequest(queueItems);

        request.startIndex = 0;
        request.currentTime = 0;

        castSession.getSessionObj().queueLoad(request,() => {
           // console.log(this.session.getMediaSession());
            console.log("queue loaded");
        },(e) => {
            console.log("queue load error");
        });

我为队列加载完全中断而烦恼。无法找出发生了什么变化。有什么想法吗？

我尝试的所有方法均失败。似乎试图加载剪辑，但出现解码错误？
