Error: Could not create output file Processed 0 frames

I am running one of the oneVPL samples- hello-vpp. I've downloaded the samples source code from oneAPI samples repository-

https://github.com/oneapi-src/oneAPI-samples.git

My OS is Ubuntu 18.04. After build, I tried the below command to get the output.
./hello-vpp ../content/input.i420 640 480 and I got the below error.

Could not create output file
Processed 0 frames

Any corrections in my command? What would be the expected output?

Solution

  • VPP sample only works with i420 video format and it's size must be 128x96. So the right command to run hello-vpp sample is:

    ./hello-vpp ../content/input.i420 128x96

    The expected output would be

    Found ApiVersion: 2.2          
SW   session created
Processing ../content/input.i420 -> out.i420
Processed 60 frames

    The output file i.e. out.i420 would be found in the build directory(Path: "\Libraries\oneVPL\hello-vpp\build") and its size is 640x480 by default.
