[FFmpeg-user] header information in generated avi file?

Hi All,
I'm trying to generate a video (mjpeg) from a jpeg image with sound.
ffmpeg -loop_input -shortest -r 5 -i f01.jpg -i f01.wav -acodec pcm_s16le
-ar 44100 -ac 1 -vcodec mjpeg -y f01.avi
The resulting avi file works on most players (although there is in some
cases confusion about when the stop playing) but, when I play it with an
application I have written using JMF (I know ...) I get no sound and no
image - although the duration is correct. The JMF application works on
other avi files.
I am assuming the above command is not producing some of the header
information? Should I be using the -type option? If so what type do I
want? I see there is an option for reading the data, producing a header
and then adding it back in, but the manual does not say how to do it; just
that it is possible.
Any help much appreciated,
peter
