4.9 Using 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=dm357
host $ make CONFIGPKG=dm357
3) Copy the binaries "dvtb-d" and "dvtb-r" to /opt/dvsdk/dm357 on the
device’s target filesystem and run it there. It must be in the same
directory as the DSP executables.
