    15  * If you press ‘R’ multiple times during one game, you will get several videos. They all will be encoded simultaneously, and each instance of game engine will use hundreds of megabytes so be careful.

    16  * It is supposed to use H.264 (MPEG-4 AVC) video codec. Binaries of `ffmpeg` for Windows include it. However, on GNU/Linux you may have stripped `libavcodec` without `libx264`, then different codec will be used which will generate several times larger files. For Ubuntu, this may help: http://ubuntuforums.org/showthread.php?t=1117283

    20   “_Some people want to do offscreen rendering and they don't want to show a window to the user. The only solution is to create a window and make it invisible, select a pixelformat, create a GL context, make the context current. Now you can make GL function calls. You should make a FBO and render to that. If you chose to not create a FBO and you prefer to use the backbuffer, there is a risk that it won't work._”

    21  SDL 1.2 does not allow to create invisible window, that’s why glut library is used. (SDL 1.3 allows it)

    22  * Video recorder relays on framebuffer extension or auxiliary buffer for offscreen rendering. If your OpenGL implementation has none of these, then video recording may not work for you. Although, framebuffer extension must be common nowadays.

    23  * Setting large resolutions for video may not work due to limitations in your OpenGL implementation. At least resolutions not exceeding your screen resolution should work.

    24  * If you entered the `/lua` chat command at any time, you cannot record videos anymore for the remainder of the game. Any active recordings will stop.
