Application Execution
3.1 Select the Application on the Nimbix Platform
Sign-in to the Nimbix Platform:
https://platform.jarvice.com/?page=compute&name=HEVC%20DRM%20U200
- Upload the cred.json you got from Accelize to Nimbix.
- See here for instructions to upload/download files on Nimbix.
- See here for instructions to upload/download files on Nimbix.
- Click on “Desktop Mode” button in the lower left of the pop-up window for an interactive shell.
- "Desktop Mode” is to explore HEVC using an interactive shell.
- Go to step 3.2.1 for the next step.
- "Desktop Mode” is to explore HEVC using an interactive shell.
- Click on “Single Command” button in the lower left of the pop-up window.
- “Single Command” for a quick demo & visual inspection using a sample 1080p input file.
- Note that because each command you run this way can run on a different fpga, this may lead to drm issues. If you are going to run multiple commands back to back, we recommend using “Desktop Mode."
- Go to step 3.2.2 for the next step.

3.2 Run the Application
You can either run a single command or launch an interactive shell where you can run many commands.
3.2.1 Run in 'Desktop Mode'
Use the following parameters and click on "Submit” button.
Machine:
- Machine Type: nx5u_xdma_201830_2
- Cores: 16
Click on submit & launch via vnc or ssh (note that initializing the instance can take some time)
To connect via vnc, click on the desktop preview
To connect via ssh, ssh nimbix@[address provided] and use the password provided.
Open a terminal and cd drmapp/
Copy the previously generated cred.json to the current directory. You can use the below methods.
- Upload to the Nimbix instance (see https://support.nimbix.net/hc/en-us/articles/208083526-How-do-I-transfer-files-to-and-from-JARVICE- )
- Create a blank cred.json and copy/paste its contents.
Unlock the fpga by typing ./drmapp.exe
Now open a second terminal and you can run ffmpeg commands.
Sample scripts are located in /home/nimbix/scripts/
If an argument is not specified, the scripts will use /samples/in.mp4 by default.
Transfer the video back and play it. ( https://support.nimbix.net/hc/en-us/articles/208083526-How-do-I-transfer-files-to-and-from-JARVICE- )
3.2.2 Run 'Single Command'

4.
Results
Once your job is complete, an “out.265” HEVC encoded sample will be available on the Nimbix FTP. You can download it and use your video player software to display it.
You can now use your own input video file by:
- Uploading it on Nimbix FTP
- Replacing “-i /samples/in.mp4” with “-i /data/{YourFileName}” in the FFMPEG arguments

./host_setup.sh -v 2020.1 -p alveo-u50 –skip-shell-flash
Note:
- Please wait for the installation to complete. During this time you may need press [Y] to continue the host setup.
- The script for host setup can be used to setup other versions XRT and shell. Please check https://github.com/Xilinx/Xilinx_Base_Runtime for more details.
