I've updated to the last Chrome version and recorded a new video (attached). Now the timeupdate seem to work well on Chrome mobile. But, in a the WebView (52.0.2743.98), the problem remain. I'm using Cordova 6.2.0 but, I don't think It have something to do with this problem, don't you ? Also, If you open the video with VLC, you can see that the duration isn't show and It seem buggy when you use the scrub bar.

In fact, duration doesn't show in Chrome and you can't use the scrub bar. But It work well on Firefox.

antoinedenis2@: MediaRecorder is a Real-Time recorder, so essentially it produces the WebM header before knowing the recording duration, see https://crbug.com/571632 . There is a bug suggesting updating the header when the recording is done in a single installment ( https://crbug.com/571632 ).
