 Replying to [comment:3 cehoyos]:
 > Decoding to pnm produces a file that neither FFmpeg nor ImageMagick can
 read.

 This was a bug in libjpeg that was fixed in 2009, no release was made
 since:
 http://libjpeg.cvs.sourceforge.net/viewvc/libjpeg/libjpeg/wrppm.c?r1=1.1&r2=1.2

 Working pgm files attached for reference.
