How should I set GopPicSize GopOptFlag GopRefDist for TFF encode ?

[l_k_1]

I changed Media SDK 2013 sample_encode a little do TFF test,  and find the setting I use will cause B frames  Mosaic ?

1.  change code add

m_mfxEncParams.mfx.GopPicSize = 24; //24;
m_mfxEncParams.mfx.IdrInterval = 0;
m_mfxEncParams.mfx.GopOptFlag = MFX_GOP_STRICT;//MFX_GOP_CLOSED; //
m_mfxEncParams.mfx.GopRefDist = 3;//3;

before ResetMFXComponents();  line 918 pipeline_encode.cpp  (see attach file )

2. command argument use 

-d3d h264 -i "d:\\samples\\out\\00000.track_4113.264_1920x1080.yuv" -o "d:\\samples\\out\\out_Intel__.264" -w 1920 -h 1080 -hw -tff

out put file see out_Intel__.264 in attach rar file

3. there are may  B frames have Mosaic, such as 

display :                 70 frame (attach png)

4. the input yuv create by tsMuxeR gui 1.10.6 from demux a m2ts file 

5. sys_analyzer information

Intel Media SDK System Analyzer (64 bit)

Hi,

The encoded stream certainly does not look good. 

Could you you please update to the latest graphics driver on you platform from here: https://downloadcenter.intel.com/default.aspx . There may be some issues with the graphics driver you're using so let's first try to eliminate that.

If that does not work, could you please share part of the raw YUV raw interlaced content so that we can try to reproduce issue on our side.

Regards,
Petter

Sorry, 
I do not use "raw YUV raw interlaced" , I will test   "raw YUV raw interlaced" later
But cuda work fine, so does x264.

Will intel auto deal this converter in future?
Or its a bad idea? 

Regards,

LK

Hi LK,

Media SDK does not use any proprietary raw format. The input assumes plain progressive or interlaced raw surfaces YUV type surfaces.

If you can share part of your raw input we can look at it and try to help you determine potential format issues.

please unzip attach file

will get 00000.track_4113.264_1920x1080.yuv file about 1.78G

Hi LK,

The raw file you provided is of YV12 progressive format and I do not see anything wrong with it.

Thanks Petter,

Back to the topic,
did you reproduce the  B frames  Mosaic situation?
Any recommand setting on how to  set code below?

m_mfxEncParams.mfx.GopPicSize = 24; //24;
m_mfxEncParams.mfx.IdrInterval = 0;
m_mfxEncParams.mfx.GopOptFlag = MFX_GOP_STRICT;//MFX_GOP_CLOSED; //
m_mfxEncParams.mfx.GopRefDist = 3;//3;

do we have the same issue ?

I was not able to reproduce the artifacts you're seing using the same configuration.

The other issue you refer to to connected with mixing progressive and interlaced frames. But as far as I can tell that is not what you're attemting to do?

Hi, Peter,

Sorry, I can use my sample_encode.exe produce every time,

Hi LK,

I do not see the any artifacts (with your input and parameters) using your executable either.  :(

Please make sure you have the latest graphics driver installed on your machine. The "2932" is a bit old.

I also noticed from your "sample_encode" log that you are not using the latest version of the Intel Media SDK. Please try to use the samples from the Media SDK 2013 R2 release.

Hi Petter,
     I uninstalled driver and OpenCL - CPU Only Runtime Package, and install  latest driver to 9.18.10.3257. 
Both   Media SDK 2013 and  Media SDK 2013 R2 works fine.
     Seems driver problem
     Thanks for your patient!

LK
