Use of existing X Window

SDL Development

Hey there… ]) powered by Linux 2.4.8 ([

Ok, be warned, this is a newbie question. :slight_smile:

Is it possible to use SDL (YUV overlay, …) on an existing X11 window? This
may sound dumb but I am trying to write a video plugin for some software and
I have to use the window for video out it has opened at startup. :frowning:

Is there any trick how I can achieve that? Thanks in advance for any help. :-)–

You can use the SDL_WINDOWID hack to do this. Set the environment variable
SDL_WINDOWID to the window id of the window you want to display to. You won’t
get any SDL events for the window, and SDL should display to it.

I haven’t tried this with the YUV overlay though, so good luck. :slight_smile:

The concept of embedding SDL into another window is generally pretty evil
in amd pf itself. Still, enough people are trying to do this for whatever
reason that I can understand the feature. But most toolkits AFAIK offer
generic buffers for whatever you want to put there. It would be less evil
to get one and turn it into a SDL_surface and draw to it, wouldn’t it?

I don’t have the source in front of me but I’m pretty sure this would
work, wouldn’t it? If not, it shouldn’t be too hard to do while you’re
