 compile with recent FFmpeg. Can someone test that it (i.e. generating
 video from NVIZ) works?

 It compiles and produces output, still there are three issues:
  * output video has problems with color. I'm not certain if it wasn't
 present also before. Might be related to the next point:
  * VBV buffer size not set, muxing may fail (see full message below)
 Output #0, mpeg, to 'asd':
     Stream #0:0: Video: mpeg1video (hq), yuv420p, 1021x766,
 q=2-31, 400 kb/s, 90k tbn, 25 tbc
 [mpeg @ 0x1b5f430] VBV buffer size not set, muxing may fail
 [mpeg @ 0x1b5f430] buffer underflow i=0 bufi=0 size=62369
  * AVMEDIA_TYPE_VIDEO was introduced only in 2010. There might still be
 around older versions - needs a change in configure magic to refuse
 compilation with older versions
