How to use QSV-FF mode in MSS 2017?

[高__超]

Hi,

I use Intel Media Sever Studio 2017 for Linux. The guide said that QSV-FF mode was added to sample_multi_transcode and sample_encode. And I found the "-qsv-ff" command-line switches in pdf of these two samples. But I failed to find "-qsv-ff" in source files of samples.

So how to use QSV-FF mode in MSS 2017?

Best wishes,

Gao Chao

Hi,

Could you give me more information?

I checked sample_multi_transcode source code and the develop guide, I can't find the parameter you mentioned.

https://github.com/Intel-Media-SDK/samples/blob/master/samples/sample_multi_transcode/src/transcode_utils.cpp

https://software.intel.com/sites/default/files/managed/09/02/Intel_Media_Developers_Guide.pdf

The other way to check if the argument is available: run "./sample_multi_transcode -?" to check in the command line argument of this sample has "qsv_ff"

Hi Mark,

We also can't find QSV-FF in latest sample multi-transcode source code.

BTW, If ADI_SCD used, VPP can't work.

Hi Mark,

David has uploaded the Media Sample Guide that mentioned QSV-FF mode in sample_multi_transcode and sample_encode. It is also mentioned in the sample readme documents.

Hi David,

You are right, the doc in MSS release package has this problem while I was checking the GitHub. I don't know if the GitHub should keep the same as the release version, but I will focus on the release document to see if this is a doc mistake or a code mistake.

Hi David and Gao,

I am quite sure this is the document mistake and "qsv-ff" parameter should not be there. I will make a request to change it but for the correct version, please refer to the GitHub for the document.

For the future, please also refer to the GitHub repo for the source code and release document. Here is the link:

Let me know if you still have questions.
