Installation and Configuration Guide for Linux® Workstations

This function receives the following parameters from the application. The values of the parameters are
extracted by the application from the VideoPreviewDevice keyword in the init.cfg software initialization
configuration file.
■ description A string that describes the video preview timing, as listed in the init.cfg file. For example,
1920x1080@5994i_free.
■ width An integer that specifies the width of the preview timing. For example, 1920.
■ height An integer that specifies the width of the preview timing. For example, 1080.
■ bitDepth An integer that specifies the bit depth of the preview timing. For example, 12.
■ rateString A string that specifies the refresh rate of the preview timing. For example, 6000i.
■ syncString A string that specifies the sync source of the preview timing. For example, freesync.
Usage example:
def
previewWindowConfigChanged(description,width,height,bitDepth,rateString,syncString):
print os.system(“/usr/bin/mySyncChangeScript --sync=”+syncString)
When the video preview timing is changed in the application, this example function calls a custom external
script, mySyncChangeScript, and passes the sync value to it. That external script could use the sync value,
for example, to trigger a sync change on the sync generator. The output of the external script is displayed
in the application terminal.
Visual Effects and Finishing applications Wiretap path translation
About Wiretap Path Translation
The Wiretap path translation service converts the syntax of a file path referred by a Wiretap server running
on a Linux workstation to a format that the client can understand. This service allows Wiretap clients, who
might be running Windows or Mac OS X, to understand file paths that are referenced by an Autodesk Creative
Finishing product to clips that have been soft-imported from a NAS, SAN, or any remote mounted storage.
For example, Lustre running on a Windows workstation can work with an Autodesk Visual Effects and
Finishing product's soft-imported clip on a SAN or NAS.
For the Windows workstation, the syntax of the path to the media files may resemble:
N:\myclips\clip1\frame1.dpx
On a Linux workstation, the path to the same media files may resemble: /CXFS1/myclips/clip1/frame1.dpx
When the Wiretap client tries to locate this clip, the path translation service converts the syntax of the path
so that the client can access the soft-imported clip from a remote storage device it has mounted locally.
Configuring the Path Translation Database
The path translation service uses a translation database. The path translation database contains a set of rules
that specify how to convert (or “translate”) a file path referred to by a source workstation (the host running
the Wiretap server) into a path that the client can understand. These rules are contained in the
/usr/discreet/wiretap/cfg/sw_wiretap_path_translation_db.xml file on each Autodesk Creative Finshing
workstation. This configuration file is read by the Wiretap server.
The translation database is an XML file that must be updated by hand as the network configurations change.
The file should be created and maintained by a system administrator who is aware of the configuration of
the network.
