Using Chrome on Mac it always records the file as video/x-matroska #806

I am specifying the type to be video/mp4 but it always generates the file as video/x-matroska, I also tried with mpeg and got same results. Any ideas why?

    createRecorder (stream) {
      const options = {
        type: 'video',
        mimeType: 'video/mp4',
        timeSlice: 1000
      }
      // create and return a RecordRTC instance.
      return RecordRTC(stream, options)
    }

Here's the error on console:

Version is 5.6.1, I tried updating to 5.6.2 but it didn't change anything.

On Firefox it works normally.

Got it working by setting video/webm;codecs=vp8 as mimeType.
