Neverless streamer can write the format and it is accepted by the
mjpegtools.  Note that there are two versions of the yuv4mpeg format,
one used by mjpegtools < 1.6.0 and one used by versions >= 1.6.0.

Recent streamer versions (>= 3.73) can write both:

$ streamer -h | grep 4mpeg
      4mpeg   yuv4mpeg (mpeg2enc >= 1.6)   [yuv]
      4mpeg-o yuv4mpeg (old mpeg2enc)      [yuv]

Mixing old streamer + new mjpegtools doesn't work, when mixing new
streamer + old mjpegtools you have to use "-f 4mpeg-o" to tell streamer
to write the old format because it defaults to the new one.  The other
two combinations should work out-of-the-box.
