IIRC this is not possible, both mplayer and xine are running in fullscreen mode and don't like other dfb applications.
I had this working over mplayer but I might have been using force-windowed in /etc/directfbrc. It is also very possible to modify mplayer and df_xine to display onto an existing window's surface, still using the BES. This way Freevo could startup and maintain several windows - for main screen, OSD, picture in picture, video previews, and full video.
I also got this working but with different aproach. I modified dfbmga plugin in mplayer. I removed all layer initialitazion and reconfiguration. Insted of creating new layer/surface dfbmga was getting control of window that was created by my application that called mplayer. Window id (that is actually plain number) i passed through dfbmga calling parameters. I think that same thing can be achieved with modification of xine. With this aproach i got smooth transition between my application and mplayer (no flickering)
Cool. I was thinking of a window id param for mplayer directfb/dfbmga too. Could you send me a patch?
There could be a problem with directfb windows on top mplayer for tv output. Dfbmga for tv output uses surfaces with YV12 pixelformat. (This format gives accelerated video on tv output) In BES output it uses RGB format. Problem is that I think that windows with RGB surface can't be on top of windows (layers) with YV12 surface.
I am unsure of this as well but I see you have raised it on the directfb list, I'll follow the thread.
Insted of using directfb windows for osd on top mplayer (xine) we can use subpicture layer. This layer is only available for tv output, but freevo as htpc software is made for tv output, so this shouldn't be a problem. This layer can display only 16 colors but with good palette choice it is enough for nice osd (note: vdr also uses 16 colors for osd). Subpicture layer can give best performance because it is independent of crtc2 layer witch mplayer uses for it's output. Only downside of this is that as I know subpicture layer is available only on matrox cards.
Most decent directfb drivers have 2 layers per screen nowadays, usually one is meant for graphics or OSD and the other for video. I was thinking of having Freevo config items to say which layer you'd prefer for each.
I use dfbmga too, only I'm using a projector now so no more CRTC2 here. I'm going to dust off the cle266 soon too, that has two layers as well.
