[Mjpeg-users] animated screen shot
by tony.chamberlain

I needed to make an animated screen shot (e.g., like a movie) of my terminal
to send to someone.  I found
http://linuxdevcenter.com/pub/a/linux/2004/03/04/screen_capture_movies.html
which works ok in general.  It uses image magic "convert" to convert a bunch
of miff files into an mpeg.  Theoretically this should work but after a
while it gives me an error message like "delegate mpeg2encode failed .. not
found".

I did a search for mpeg2encode for Linux CentOS 4.8 (what my machine is
currently at) but could not find it.  I did find mpeg2enc from the mjpeg
package.  So I built it and linked it, but it was called incorrectly.

The original mpeg2encode is called as

     mpegencode inputfile outputfile

however, mpeg2enc has different parameters.  I figured out to use "-o output"
for the output file name, but I cannot figure out what parameter to
specify for the input (I made a dummy mpeg2encode to call mpeg2enc the
correct way).  I tried

    cat inputfile | mpeg2enc -o outputfile
and
    mpeg2enc -o outputfile inputfile

but both give errors about YUV or something like that.

What is the correct way to call mpeg2enc analagous to

   mpeg2encode input output

??

Thank You
