            Bug ID: 784971
           Summary: matroskamux: Writes one cluster per audio frame
    Classification: Platform
           Product: GStreamer
           Version: 1.12.0
                OS: Linux

If you look with mkvinfo, each Opus frame gets its own cluster. That's
introducing a huge amount of overhead. At least having multiple frames per
block would be good, even better if we could do lacing.
