matroska webm muxer setting media duration on EOS

[putrasto]

Hello,

I have to save live stream vp8+opus to webm file
because this is live stream i can understand that during writing the webm
file does not have media duration.
The problem is until EOS the media duration still not available.

How to set correct media duration when received EOS?
