Comment (by jomeier):

 {{{
 ffmpeg -f lavfi -i testsrc=size=720x576:rate=25 -pix_fmt yuv420p -vcodec
 mjpeg -s 360x288 -qscale:v 5 -f matroska -live 1 - | ffplay -i -
 -window_title M-JPEG_Live
 }}}

 Didn't resolve the issue. CPU Load increased from 1% to 13% over 24 hours.
 It really seems as if there's a problem with the matroska container.


 {{{
 -f mpeg1video
 }}}

 and


 {{{
 -f mjpeg
 }}}

 work like a charm.

 Any good ideas? This effect is beginning to drive us crazy :-) !
