rewritten recorder using ffmpeg libs (without SDL_ffmpeg)

 * SDL_ffmpeg was broken and is hard to get
 * my implementation allows specifying an output codec. if the codec supports the screen's pixel format, no conversion is performed saving lots of performance (also beneficial for post-processing a recorded video)
