visit_utils is a pure python module distributed along with Visit's Python interface. It provides a simple interface to encode movie files and methods that wrap more complex VisIt Python command sequences to simplify a few common use cases. It also provides a stand alone PySide based annotation rendering API.
Here we provide details on the encoding and engine launching modules:
visit_utils.encoding provides methods that allow you to use movie encoders (e.g ffmpeg) to encode movies from sequences of image files and extract image files from movie files.
Methods:
- param ifile
Input file.
- param opattern
Output file pattern. Requires a printf style # format like "file%04d.png".
visit_utils.engine provides an interface to launch VisIt engines that uses installed host profiles.
Methods:
- param nprocs
Number of MPI tasks
- param methods
Launch Method (srun, etc)
- param ppn
MPI tasks per node
- param part
Partition
- param rtime
Job time
- param vdir
