Hello, I updated to current git and find the video plugin. What exactly is it supposed to do? I want to test it but I don't know exactly what to test.... Enabling it did not make any difference (it loaded successfully).

A video playback client basically copies video data to a pixmap and sets an X property on a client window that describes the image format of the data and where it should be rendered. The compiz video plugin will scale and perform necessary colorspace conversions when compositing the desktop. It provides very efficient playback of video on a composited desktop and it requires much less resources than e.g. XVideo as no intermediate buffer is required and hence also no accelerated offscreen rendering. RGB and YV12 image formats are currently supported but it's of course very easy to add support for additional formats. YV12 format requires GL_ARB_fragment_program and 8 bpp alpha only GLX pixmap support. The server doesn't provide alpha only pixmaps today. The attached patch adds an alternative PICT_a8 visual to composite and that is enough for xgl to support alpha only GLX pixmaps (not sure it will work with aiglx or nvidia's driver, I would guess not). Adding an alpha only X visual might be a bad idea. It doesn't cause any issues with the clients I've been running but I've seen that GDK thinks the server is broken and spits out some warnings when it finds a visual with masks set to 0. Might be a better idea to just add the fbconfig and no visual but the current GLX code in the server relies on every fbconfig having a matching X visual so it will need a bit more work and I'd like some feedback before I start doing anything like that. I've created a patch to mplayer's xv output code that makes it use compiz video interface when available. Works pretty well and it even dynamically detects when the compiz video interface isn't available anymore and then switches to xv instead. Similar patches can easily be created for other video playback clients, of course. - David ______________________________> > _________________ > compiz mailing list > compiz@lists.freedesktop.org > http://lists.freedesktop.org/mailman/listinfo/compiz > >On 3/7/07, dragoran <drago01@gmail.com> wrote:> > Hello, > I updated to current git and find the video plugin. > What exactly is it supposed to do? > I want to test it but I don't know exactly what to test.... > Enabling it did not make any difference (it loaded successfully). > > _______________________________________________ > compiz mailing list > compiz@lists.freedesktop.org > http://lists.freedesktop.org/mailman/listinfo/compiz >-- Andr?s Blanco Morales -------------- next part -------------- An HTML attachment was scrubbed...

You will need to patch xorg and mplayer for it to work. http://lists.freedesktop.org/archives/compiz/2007-March/001576.html
