As an additional comment...
Current version of mjpegtools expects a different parameter from the one
that kmediafactory is invoking as can be seem on this error log:

The options supported by ppmtoy4m are:

usage: ppmtoy4m [options] [ppm-file]
Reads RAW PPM image(s), and produces YUV4MPEG2 stream on stdout.
Converts computer graphics R'G'B' colorspace to digital video Y'CbCr,
and performs chroma subsampling.
If 'ppm-file' is not specified, reads from stdin.

-I x interlacing [p]

Kmediafactory 0.5.2 was released on 19/06/2006, maybe upgrading will fix
the problem?

kmediafactory seems to depend on mjpegtools to work.
