答复: Why there is not time line display in html5 inline-video in Android4.0(ics)?

There is not time line display in html5 inline-video in Android4.0(ics), with webkit version of 

However, in my investigation, it shows that the timeline container and time line are all created and added
into panel of media controller.

Moreover, the logs show that in the play interval, the time display is updating:

01-02 00:02:07.360 D/MediaControlRootElement( 1633): updateTimeDisplay...
01-02 00:02:07.360 D/MediaControlRootElement( 1633): Allow the theme to format the time...
01-02 00:02:07.360 D/RenderTheme( 1633): formatMediaControlsCurrentTime:0.000000
01-02 00:02:07.360 D/RenderTheme( 1633): formatMediaControlsRemainingTime:-1.000000


So, what is wrong with the time line drawing process?

Any reference about time line drawing of html5 video-inline controls are welcomed.

Thank you.
