Intel Transcoder failed : Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate

[syamsudin__arie]

I want to reduce bandwidth usage by using Intel Transcoding.

I was given a tutorial or steps by ezserver support:

http://www.ezhometech.com/document/intel_ffmpeg.txt

After I search on google, it turned out that MediaServerStudioEssentials2018R1.tar.gz only supports Intel Generation 6.7 and 8.

https://software.intel.com/en-us/articles/intel-media-sdk-release-notes
https://software.intel.com/en-us/articles/driver-support-matrix-for-media-sdk-and-opencl

Now I have used intel generation 7 but it still failed.

I use CentOS 7.4.

This is the error result :
