amazon-chime-sdk-js 显示自我视频

Question

我在文档https://aws.github.io/amazon-chime-sdk-js/index.html的帮助下使用chime js SDK创建了一个视频应用程序

            const indexMap = {};

            const acquireVideoElement = tileId => {
              for (let i = 0; i < 16; i += 1) {
                if (indexMap[i] === tileId) {
                  return videoElements[i];
                }
              }
              for (let i = 0; i < 16; i += 1) {
                if (!indexMap.hasOwnProperty(i)) {
                  indexMap[i] = tileId;
                  return videoElements[i];
                }
              }
              throw new Error('no video element is available');
            };

            const releaseVideoElement = tileId => {
              for (let i = 0; i < 16; i += 1) {
                if (indexMap[i] === tileId) {
                  delete indexMap[i];
                  return;
                }
              }
            };
            const observer = {
              videoTileDidUpdate: tileState => {
                if (!tileState.boundAttendeeId || tileState.localTile || tileState.isContent) {
                  return;
                }

                meetingSession.audioVideo.bindVideoElement(tileState.tileId, acquireVideoElement(tileState.tileId));
              },
                videoTileWasRemoved: tileId => {
                    releaseVideoElement(tileId);
                  }
            };

            meetingSession.audioVideo.addObserver(observer);
            const audioMix = document.getElementById('meeting-audio');
            meetingSession.audioVideo.bindAudioElement(audioMix);
            meetingSession.audioVideo.start();
            meetingSession.audioVideo.startLocalVideoTile();

效果很好，我可以看到所有加入会议的与会者。但我还需要在标签中显示我的视频。有可能吗？

在您的videoTileDidUpdate 中，为了显示您的视频磁贴，您在哪里绑定本地磁贴，我看到如果tileState.localTile 是true，您正在返回并且bindVideoElement 没有被调用，因此您的 localTile没有出现。您能否删除 localTile 检查，看看这是否可以作为初始步骤。
