Hi,

  Matroskamuxer converts the buffer of timestamps directly to the muxed stream
time. Which leads to some issues when you feed it a stream that doesn't start
at timestamp 0. Most notably, some frames can get timestamps which don't fit
inside the files duration..

I'll attach a patch that handles this very naively, which makes stuff work for
my application. But as i'm not sure how muxers should handle segments, it's
probably wrong and there could be some regressions when you mixing multiple
streams.

Is there any documentation about how muxers are supposed to handle segments?
