Actually, one more thing. yu are using the mediaplayer plugin right? how does the HDMU media centre work ? identical issues. Need to rule out a plugin to be causing this. (as I haven't heard such issues from the oatv users (which use the same adbox mediasink.. but the E2 code and some plugins may differ - not causing some problems.
when you start the movie, do you see progress bar, and it only disappears when you use ffw/rev?
and regarding ffw, what does actually happen> does it actually ffw? I see different behavour in movieplayer to media centre. movieplayer, i press ffw and it ffw a bit and then continues playing. if i perss & hold ffw, then I get the seek popup..
in media centre, when i press ffw, it get 2x, press again 4x..
what is your expected behaviour of those described? (i.e how does it behave with the old audiosink)
as the progress bar is based on audiosink time from the box, something in the ffw, unpause doesn't pass decode time and therefore progressbar is blank.
but I think only e2 debug logs with some gstdebug will tell us that.
