Unable to seek to a point just after the recording

[Tuizi]

Record a video on the website: https://www.webrtc-experiment.com/RecordRTC/
Ideally a video of 20 sec for example.

When you click on "Stop Recording" the video you just recorded is playing, but notice that you cannot seek to a position in the video. After the video ended playing, now you are able to seek to a position, it's only the first play where there is the issue. Also the duration of the video is Infinity the first time, after it is correct.

I close same issue than #145 . Work well in Firefox but not in Chrome, seems to be related to the issue open in Chromium
