Follow the instructions based on your deployment method.
An access key is required to authenticate a user and grant them access to the application based on their entitlements. To obtain your account access key, follow these steps:
Note: The resulting access key will enable all entitlements within your account. If you have not yet obtained entitlements from the "TRY OR BUY" section above, you must do so before following these steps for generating your access key.
The Xilinx Runtime (XRT) host application is supported on Ubuntu 16.04 /18.04 and CentOS 7.x. With sudo access, use the following command to download and run the setup script:
git clone https://github.com/Xilinx/Xilinx_Base_Runtime.git && cd Xilinx_Base_Runtime
./host_setup.sh -v 2019.1 -p alveo-u200
Note:
With sudo access, use the following command to run the utility script to install docker.
cd Xilinx_Base_Runtime/utilities
./docker_install.sh
source Xilinx_Base_Runtime/utilities/xilinx_docker_setup.sh
docker pull hubxilinx/vnova_pplus_alveo_u200:ppxde-demo

Description of command arguments:
-v /tmp/cred.json:/vnova_pplus/cred.json:Z
- Map local cred.json dir : container dir-v /dev/shm:/io:Z
- Map the local dir : container dir for input & output file$XILINX_DOCKER_DEVICES
- Environment variable set by the host setup script-y
- Overwrite output files without asking-s WxH
- Resolution of input-pix_fmt
- Pixel format of input file (yuv420p)-c:v codec
- Codec used for encoding (For this demo, pplusenc_hevc, which specifies LCEVC with a HEVC base codec)-base_encoder codec
- Code used for the base (ngcodec_sdx_hevc specifies the HEVC encoder from Xilinx-NGCodec running on the FPGA)-stream_loop
- Specifies the number of times to loop over the input file during encodes, set to -1 for infinite-i
- Location of input file to be encoded-b:v
- Specifies the encoding bit rate, e.g 4500k will encode at 4.5mbps
Once your job is complete, an “output.ts” 4K HEVC encoded sample will be available in "/dev/shm". You can use The Perseus decoder on Microsoft Windows 10 to display it. You will need to install these 2 apps:
