> I propose very simple 1-pixel progress bar which can be turned on or off
> during
> playback by pressing a button (I use 'L', from 'line'). By default the bar

> I choose bright green color (#00ff00) for the part to the left of a current
> position and pure black for the part to the right.

> Draft patch is applied. One global variable ('static int
> show_progress_line')
> and one function ('static void video_progress_line_display(VideoState
> *is)')
> have been added. Also the existing 'video_display()' function has been
> moved
> below 'get_master_clock()' as the latter is used in the new function.

> What do you think?
