Hello Andya,
You access the GOP size from the mfxVideoParam class. In the sample_encoder function, you can set this parameter in the InitMfxEncParams() function. You can find more information on p125 and p129 of mediasdk-man.pdf in the <MEDIASDK>/docs.
Please let me know if I am misunderstanding your question.
Thanks.

i see :
Number of pictures within the current GOP (Group of Pictures); if
GopPicSize=0, then the GOP size is unspecified. If GopPicSize=1,
only I-frames are used. See Example 14 for pseudo-code that
demonstrates how SDK uses this parameter
but i don‘t know Example 14,where ‘s it,i not found in <MEDIASDK>/samples,can u provides detailed information?
Hello Andya,
You can find Example 14 on p123 of the same document (mediasdk-man.pdf in the <MEDIASDK>/docs).
Let me know if you have more questions.
