There is a public domain encoder and player available from Berkeley. You can ftp the package:
ftp://mm-ftp.cs.berkeley.edu/pub/multimedia/mpeg/bmt1r1.tar.gz
It is well documented.
(If you are only in need of an mpeg player, you may want to try the one at http://www.geom.umn.edu/software/mpeg_play)
The encoder requires that images be in yuv or ppm format. You can use DX to write yuv format images by specifying "yuv" as the format to WriteImage. An example visual program, "write_yuv.net", is included in this directory. It writes a series of yuv-format images: iso.0.yuv, iso.1.yuv, etc.
Use the encoder to create an mpeg file. You need a param file; one is included here, called "default.param". For example:
.../mpeg_encode default.param
Then you can use the player to play the mpeg movie. For example:
.../mpeg_play output.mpg
WHAT IF YOUR MPEG DOESN'T LOOK RIGHT?
Note that Data Explorer v 3.1 had a bug which caused incorrect yuv images to sometimes be written. In later versions this bug has been fixed (to check your version, type "dx -version" or use the Product Information choice from the Help menu).
Make sure that you are writing only one frame per file (the default behavior of WriteImage yuv format is to append new frames if a file already exists; set the frame parameter to 0 to ensure that new frames overwrite previous frames).
Make sure that you have
BASE_FILE_FORMAT YUV
YUV_FORMAT ABEKAS
in your .param file.
