Testing the Build Environment

4.8Testing the Build Environment

To test your DVSDK software installation, you can build one of the Codec Engine servers. This server is a DSP-side application. Building it tests the installation of DSP-side development components.

To build the video_copy server, follow these steps:

1)Go to /home/<useracct>/dvsdk_#_#/codec_engine_#_#/examples and open the build_instructions.html file.

2)Follow the step-by-step instructions for building examples. When you are editing the xdcpaths.mak file, note that the DVSDK installation does not include the cetools directory, so you will need to set the USE_CETOOLS_IF_EXISTS variable to 0, and modify additional variables to point to the locations of xDAIS, DSP/BIOS Link, CMEM, and Framework Components.

3)Go to the video_copy server directory. (/home/<useracct>/dvsdk_#_#/codec_engine_#_#/examples/ servers/video_copy) to inspect the built server.

4.9Using the Digital Video Test Bench (DVTB)

The Digital Video Test Bench (DVTB) is a Linux utility that was developed to execute end-to-end data flows using the DVSDK for any platform. DVTB uses the Codec Engine VISA APIs and Linux driver peripheral APIs to encode and decode video, image, audio and speech streams.

Using DVTB, you can configure codecs and/or peripherals before starting a data flow. This enables you to try different use case scenarios and evaluate the system.

The DVSDK installation places DVTB in the /home/<useracct>/dvsdk_#_#/dvtb_#_#_# directory, where #_#_# is the DVTB version number).

To install DVTB to the target file system, perform the following steps on the host machine where the DVSDK has been installed:

1)Make sure the Rules.make file defines PLATFORM correctly as described in Section 4.6.

2)Perform the following commands:

host $ cd /home/<useracct>/dvsdk_#_#/dvtb_#_#_#

host $ make clean CONFIGPKG=dm6446

host $ make CONFIGPKG=dm6446
