CR: Only do FastForward in PLAYING state

Synopsis:

    There is TrickPlay interface for Helix plugins.

    https://helix-client.helixcommunity.org/nonav/2005/devdocs/TKP-SOD-001-TrickPlay.html

    however some plugins don't support it well, for example: ogg, wmv, etc.

    there is some issue if switch between these plugins in FastForward mode.

    here is an special case :

        try playback MPG I/II but it is not support by the engine,

        (there will be some error said the stream is unsupported);

        then set FastForward mode.

        after above steps, there will be some issue to playback other supported contents.

    we try to do FastForward only when the player in PLAYING state, it will overcome the above issues.
