Video file creation (emf)
To be able to play movies with the STemWin API functions it is required to create files of the
STemWin specific EmWin movie file format. There are two steps to generate an emf file:
1.
Convert files of any MPEG file format into a folder of single JPEG files for each frame
(see
Figure 79 ). The free FFmpeg available at ffmpeg website can be used.
2. Create an emf file from JPEG file using JPEG2Movie tool available in STemWin
package ( Figure 80 ).

These steps can be done once using a predefined batch (included in the STemWin
package) as shown in
Figure 81 .
For more information about how to use the emf generation batches, refer to the STemWin
User and Reference Guide (UM3001).
