Issue with oneVPL samples

I am unable to run any VPL samples on my host machine. When I am trying to run any hello samples it's showing the below error.

I installed basetoolkit and am trying to run the hello_encode sample with the below command.

./hello-encode -i ./P.i420 -w 1920 -h 1080

When I run the above command, it always throws the below error.

Cannot create session -- no implementations meet selection criteria Encoded 0 frames

These are the OS details: NAME="Ubuntu" VERSION="18.04.6 LTS (Bionic Beaver)"

These are the CPU details:

Solution

  • Possible reason for getting such error is that you haven't sourced your environment variables. Source the setvars.sh script given in oneapi folder to proceed further:

    1. Run as root/super user:

    sudo su

    1. Source environment variables as follows:
    source /opt/intel/oneapi/setvars.sh
    1. Run the command that you've been trying to run:
    ./hello-encode -i <input file> -w 1920 -h 1080

    Hope this helps!
