Putting Demo Applications in the Third-Party Menu

Additional Procedures

A-3

uses relative references to access them. For example, the following
directory structure might be used in the archive:

|-- app.sh

|-- data

| |-- datafile1

| `-- datafile2

|-- logo.jpg

`-- readme.txt

To check the format of the file you create, execute the following
command in Linux. The result should say "gzip compressed data".

file <filename>.tar.gz

3) Put your archive in the "thirdpartydemos" subdirectory of the target

installation directory. This is where the DVSDK software was installed
on the target file system. The default target installation directory is
/opt/dvsdk/dm6467, so the default location for demo archives is
/opt/dvsdk/dm6467/thirdpartydemos. Do not extract the contents of
the archive in this location. Extraction is performed behind-the-
scenes each time the demo is run.
