I am using Ubuntu 20.04 beta:

$ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu Focal Fossa (development branch)
Release:	20.04
Codename:	focal

Running the example code from https://github.com/Intel-Media-SDK/MediaSDK/wiki/Intel-media-stack-on-Ubuntu gives me this error:

Hi Penghe,

Sorry for the late response.

From the log messages, it seems the input file has a problem and input file was missing. 

Could you double check?

Hi Mark,

You are right. I tried it again and it works this time with the yuv file provided. Thanks a lot for the help!
