Today, I tried out, if I can pipe the output into ffplay, instead of ffmpeg. It worked, but after the render, Minecraft crashed, because it couldn't find the file, that got rendered (Mainly because ffplay wasn't saving anything...)
I also found a thread, where the reporter, had the same crash report, but probably without any command line args.
