Linux version of libmfxswXX library

[Dmitry_R_1]

Where can I find Linux version of libmfxswXX library with software H.264 encoder enabled?

Hi Dmitry,

Which version are you using?

If you installed the release version, you should find it under /opt/intel/mediasdk/lib64; if you built and installed open source Media SDK, you will not have the software version.

Hello Mark,

Archive MediaServerStudioProfessional2018R2.tar.gz contans SDK2018Production16.9.tar.gz, which contains intel-linux-media-generic-16.9-00005.tar.gz

Inside /opt/intel/mediasdk/lib64 only hardware version, but not software:

libmfxhw64-p.so.1.27

The similar file is in Centos package (intel-linux-media-16.9-00005.el7.centos.x86_64.rpm)

I cannot find libmfxsw.

Does anyone tell me whether Media SDK support encoding on Linux on Intel processors without GPU? I cannot find any official information about it.

Hi Dmitry,

In Media SDK, we support software codec as the fallback mode, meaning if the hardware path doesn't work temporarily, application can switch to software mode to keep the user experience smooth.

If you are using Xeon platform, you can check our software codec called SVT: https://01.org/svt

Hope this helps.

Hello Mark and thank you for response. We will be glad to use SVT, but currently it does not support H.264. We are planning to use it when we start to use more advanced codecs.

Concerning Media SDK under Linux here is a cut from readme-dispatcher-linux.pdf:

Search the default SDK implementations in the default system paths or path addressed by LD_LIBRARY_PATH environment variable by first searching for platform-specific one (libmfxhw64.so) and then software (libmfxsw64.so).

Unfortunately I cannot find libmfxsw64.so itself so I asking where can I find it if it does not exist in MediaServerStudioProfessional2018R2.tar.gz/SDK2018Production16.9.tar.gz

[Mark_L_Intel1]

Ok, let me check multiple version and get back to you.

Yes, I confirmed we have remove libmfxsw64.so from the release package from 2018 R2. But it is still available in 2018 R1.

So it should be MediaServerStudioProfessional2018R1.tar.gz/SDK2018Production16.8.tar.gz

Thank you Mark, I've found the required library.

You said "we have remove libmfxsw64.so from the release package from 2018 R2". If this was intentional what is the future for this library and will it be available in next releases? Is there any official Intel announcement concerning H.264 software implementation - will it be deprecated or moved into another software product?

Hi Dmitry,

Sorry for the late response and thanks for good reminder.

I have asked your question to dev team and I am waiting for their response now, I will keep you updated.

Mark
