Timestamp of each frame

I need to save the timestamp ( millisecods ) of each frame. ( Also i need only the video not the audio. How its possible with RecordRTC?

This is my code:

recordAudio = RecordRTC(stream, {
            frameRate: 30,
            quality: 1,
            onAudioProcessStarted: function() {
                recordVideo.startRecording();
            }
});

recordVideo = RecordRTC(stream, {
            type: 'video'
});

recordAudio.startRecording();`

The stream you would pass in would have video: true, audio: false, this is not RecordRTC’s job. However, RecordRTC does not / can not give you the timestamp per frame as there is no way to inject the ondataavailable callback at this time.

I just follow your suggestions:

• I override the two individual files: RecordRTC and MediaStreamRecorder
• I just use your lines on code:

        recordVideo = RecordRTC(stream, {
            type: 'video',
            timeSlice: 1000, // 1 second
            onTimeStamp: function(timestamp, allTimeStamps) {}
        });
        recordVideo.startRecording();

/**/

var msRecorder = recordVideo .getInternalRecorder();
var allTimeStamps = msRecorder.timestamps;
console.log( allTimeStamps );

But nothing happen, no error and no message on console log.
