RemoteMediaClient对某些视频失败

Question

在我正在做的SessionManagerListener的onSessionStarted（）回调中，

final RemoteMediaClient rmc = getRmc();
rmc.addListener(mRemoteStatusUpdateListener);

//Video url
MediaInfo.Builder bulider = new MediaInfo.Builder(url);
MediaMetadata md = new MediaMetadata(MediaMetadata.MEDIA_TYPE_TV_SHOW);

//Title for notification
String title = (episodeName + " " + seriesName).trim();
md.putString(MediaMetadata.KEY_TITLE, title.isEmpty() ? getString(R.string.app_name) : title);

//Images for notification
String imagePath = getThumbnailImage();
if (imagePath != null) {
    md.addImage(new WebImage(Uri.parse(imagePath)));
    md.addImage(new WebImage(Uri.parse(imagePath)));
}

//Adding licence
JSONObject j = new JSONObject();
try {
    j.put("widevine_key", mStreamCustomFromServer);
    j.put("playready_key", mStreamCustomFromServer);

    j.put(Constants.PlayListConst.EPISODE_NAME, episodeName);
    j.put(Constants.PlayListConst.SERIES_NAME, seriesName);

} catch (JSONException e) {
    e.printStackTrace();
}

MediaInfo.Builder mi =
        bulider.setStreamType(MediaInfo.STREAM_TYPE_BUFFERED)
                .setContentType("video/mp4")
                .setMetadata(md)
                .setCustomData(j);

//We send a custom message to cast server to clear the player state (custom message sending part is not put here) and then load media as follows

rmc.load(mi, true, seekTo).setResultCallback(new ResultCallbacks<RemoteMediaClient.MediaChannelResult>() {
        @Override
        public void onSuccess(@NonNull RemoteMediaClient.MediaChannelResult mediaChannelResult) {

            //Handling success
        }

        @Override
        public void onFailure(@NonNull Status status) {

            //Handling failure

        }
    });

rmc.load（mi，true，seekTo）没有为某些视频提供回调。此后没有进度更新回调。但视频将在Chromecast中播放。 在myplayer.js文件的onLoad（）方法中，我正在做，

myPlayer.CastPlayer.prototype.onLoad_ = function(event) {
    var info=new cast.receiver.MediaManager.LoadInfo((event.data),event.senderId);
    var initialSeek = info.message.currentTime;
    var stream = {
        startTime: initialSeek,
        url: info.message.media.contentId,
        protData: {
            'com.widevine.alpha': {
                laURL: 'http://widevine.licensekeyserver.com/',
                cdmData: info.message.media.customData.widevine_key,
            },
            'com.microsoft.playready': {
                laURL: 'http://sldrm.licensekeyserver.com/core/rightsmanager.asmx',
                cdmData: info.message.media.customData.playready_key,
            }
        }
    };

    // Initialize player.
    videoKeyOs = new MediaPlayer();
    videoKeyOs.init(videoHtml);
    videoKeyOs.setAutoPlay(info.message.autoplay);
    videoKeyOs.setConfig({
        '// Debug.level': 'The level for output debug messages (0=none, 1=error, 2=warn, 3=info, 4=debug)',
        'Debug.level': 1
    });
}

getRmc（）方法，

private RemoteMediaClient getRmc() {
    CastSession cs = getCurrentSession();
    if (cs != null) {
        return cs.getRemoteMediaClient();
    }
    return null;
}

getCurrentSession（）方法，

private CastSession getCurrentSession() {
    SessionManager sm;
    if (mCastContext != null && ((sm = mCastContext.getSessionManager()) != null)) {
        return sm.getCurrentCastSession();
    }
    return null;
}

如果我将加载方法添加超时，

rmc.load(mi, true, seekTo).setResultCallback(new ResultCallbacks<RemoteMediaClient.MediaChannelResult>() {
        @Override
        public void onSuccess(@NonNull RemoteMediaClient.MediaChannelResult mediaChannelResult) {

            //Handling success
        }

        @Override
        public void onFailure(@NonNull Status status) {

            //Handling failure

        }
    }, 10000, TimeUnit.MILLISECONDS);

然后调用onFailure，状态= [Status {statusCode = TIMEOUT，resolution = null}]

我想知道为什么某些视频失败了。有人请帮我找到解决方案。 在此先感谢：）
