RecordRTC:以mp4容器而不是matroska记录

我正在使用RecordRTC库来录制屏幕和音频。我需要mp4容器中的h264编解码器,但是在我的设置中,我在matroska容器中获得了h264编解码器。我正在使用以下代码:

this.captureUserMedia(screenConstraints, function(screenStream) {
            that.captureUserMedia(audioConstraints, function(audioStream) {
                var arrOfStreams = [screenStream, audioStream];

                var options = {
                    type: 'video',
                    mimeType: 'video/webm\;codecs=h264', // or video/webm\;codecs=h264 or video/webm\;codecs=vp9
                    audioBitsPerSecond: 192000,
                    recorderType: MultiStreamRecorder,
                    video: {
                        width: desiredWidth,
                        height: desiredWidth / screenAspectRatio
                    }
                };

                that.recorder = RecordRTC(arrOfStreams, options);

                that.recorder.startRecording();

                that.btnStopRecording.onclick = function () {
                    console.log("recording stopped");
                    that.recorder.stopRecording(that.postFiles.bind(that));
                }
            });
        });
    }

RecordRTC库是否可行?这是issue on project's github,但他们推荐我使用的选项。是使用ffmpeg从matroska重新打包到mp4的唯一方法吗?
