Installation Overview

8) Select Debug > Run to execute the sample test application.
The sample test application takes the input files stored in the \Client\Test\TestVecs\Input sub-
directory, runs the codec, and uses the reference files stored in the
\Client\Test\TestVecs\Reference sub-directory to verify that the codec is functioning as
expected.
2.5 Configuration Files
This codec is shipped along with:
‰ Encoder configuration file (configparams_1080.cfg) - contains the input
and output filenames, and the configuration parameters required for
the encoder. The configparams_1080.cfg file is available in the
\Client\Test\TestVecs\Config sub-directory.
A sample configparams_1080.cfg file is as shown.
