just a little question about conversion of formats. I'm using the v4l API to develop an application.
To do recording from my program, I need to set the format of video_mmap to VIDEO_PALETTE_RGB24. To display on screen though, the format has to be VIDEO_PALETTE_RGB32.
Is it possible to convert the first format into the second one? If yes, how?
Just throw it on a sdl surface and let sdl do its magic :-) Are you using 32 bits/channel for what? Is there any alpha information?
or if you don't want to use SDL, you can for example download MPlayer sources and use the contents of the postproc directory (the rgb24to32 function might interest you)
