Set Encoding Frame Order

[Mohammad_T_1]

Hello,

I am using Intel Media SDK 388 version 1.16. I do Encode raw data in h264 and it's working fine. Encoding parameters are:

m_mfxEncParams.mfx.EncodedOrder = 0; 
m_mfxEncParams.mfx.IdrInterval = 0;
m_mfxEncParams.mfx.GopPicSize = 24;
m_mfxEncParams.mfx.GopRefDist = 3;

 m_mfxEncParams.mfx.CodecProfile = MFX_PROFILE_AVC_MAIN;   

The encoded h264 file is working fine. Output frames are in orders: IPBBPBBPBB... and so on.

But for one requirement i want to change the Frame orders as IBBPBBPBBP... and so on.

I tried to change Encode order by changing m_mfxEncParams.mfx.EncodedOrder = 1; but not succeeded.  

So please guide me, how can in set Encoding Frame order. 

Thank you

Hi Mohammad,

First of all you should update your Media SDK up to Media SDK 2016 R2.

To have gop-structure "IBBPBBPBBP" you should set m_mfxEncParams.mfx.EncodedOrder = 1; and specify type of frames by FrameType enumerator (see details in mediasdk-man.pdf).

Best wishes,
