Support for Atom X6425E processors in Linux

Hardware: Atom X6425E processors,
OS: Ubuntu 20.04,  kernel: 5.15.0-52-generic.


After installing Intel Media SDK 22.5.4, the 'sample_encode' program does not run properly. The error return value is as follows:

Does the x6425E processor not support the Linux version of the Intel Media SDK?

Hi,


Thank you for posting in Intel Communities.


Could you please confirm the Media SDK version? In the screenshot shared, it is showing 21.2.3

Thanks for your reply.
 
I used Intel MediaSDK 2022Q3 Release - 22.5.4 and Intel Media SDK 21.2.3 respectively and running the sample encode program both returned 'MFX_ERR_UNSUPPORTED(-3)'.

Also, I looked at the source code of libmfx and found out the problem. 
As shown below, for 'H264' encoder, the encoder parameters 'mfx.RateControlMethod', currently only 'CQP' is supported, the others are not. So the default parameter is used to return an error.

I would like to know if this is normal on the x6425e processor? (CQP support only)
 
At the same time, the H265 encoding has the same problem of not working.

Hi,

 

We were able to run sample_encode on oneVPL HW implementation . Could you please switch to oneVPL and try running the sample?

Hi,


We haven't received any update from your end. Were you able to run the sample code?

Thank you for your reply.

I did not switch to oneVPL and try to run the sample.

 

I switched my ubuntu system to intel-iot Ubuntu 20.04.5 and retried the Media SDK and now I can run the sample program properly.

 

 I think this may have something to do with the kernel of the Ubuntu distribution, and I will now continue to develop with the Media SDK on intel-iot Ubuntu 20.04.5.

 

Thanks again
