[MPlayer-dev-eng] MPlayer -> Java Component ---> MPlayer and Video Annotations.

[Almerindo Rehem]

Thanks!

is It possible to paint over the window?

I work with MPEG-7 and video annotations. My software works fine whith
Quicktime (quicktime for java), but i want to use MPlayer (because is
Open Source). The problem is: How to redirect the video display to a
Canvas component / JComponent or any java component  ? 

If this is possible, I could to insert the component in my software, and
draw over the video (making and showing the annotations whith MPEG-7).

Any sugestion ?


Hi Almerindo,

methods), you could pass it to the MPlayer via option -wid <window_id>.
I tried it with a Visual Basic window and it worked.

runs in slave mode (-slave option), is always-on-top (slave command
vo_ontop). I even resize the MPlayer window to fit into a certain area
on my JAVA JFrame. The only thing that sucks is the window decoration of
the MPlayer window.
