Linux的/ DLPDLCR2000EVM：Can Beaglebone green make the DLPDLCR2000EVM play a sample video on the User Guide?

Linux/DLPDLCR2000EVM: Linux/Beaglebone Black/Beaglebone Wireless/DLPDLCR2000EVM: Video doesn't work

Part Number: DLPDLCR2000EVM

Tool/software: Linux

I have some troubles with the DLPDLCR2000EVM, I followed the guide of "", but at the end it doesn't works. I'm using a Beaglebone Black Wireless with Debian 8.9. When I execute next code:

export DISPLAY=:0

cd /opt/scripts/device/bone/capes/DLPDLCR2000/

python MplayerTest.py

I got next messages:

root@beaglebone:/opt/scripts/device/bone/capes/DLPDLCR2000# python MplayerTest.py
set slave address: 27
Make sure the display port is set. For example export DISPLAY=:0

Test failed Exception

And if I just run " root@beaglebone:/opt/scripts/device/bone/capes/DLPDLCR2000# mplayer nhd_test.mp4" I got:

root@beaglebone:/opt/scripts/device/bone/capes/DLPDLCR2000# mplayer nhd_test.mp4

    Hello User,

    Welcome to the E2E forums, and thanks for your interest in our DLP technology.

    There are two things you should verify here. First, it appears that mplayer (the video player used in the test script) is not installed. You should use apt-get to install mplayer to your BeagleBone.

    In addition, you should also verify whether the cape overlay for the DLP2000EVM is installed properly. You can use the capemgr tool to do this:
    https://elinux.org/Capemgr

    If the cape is NOT installed, you should consider installing it manually to your system, which can be done by following the link below:
    e2e.ti.com/.../663939

    I hope this helps. Let me know if you have further questions.

    Best Regards,
    Philippe Dollo
