How to insert key frame with Intel SDK?

[lance7]

Hi all,

In early thread, we can found the insert key frame function,
that is, mfxStatus MFXVideoENCODE_EncodeFrameAsync(
mfxSession session,
mfxEncodeCtrl *ctrl,
mfxFrameSurface1 *surface,
mfxBitstream *bs,
mfxSyncPoint *syncp);

And use mfxEncodeCtrl to control the I frame,

my new question is whom can invoke this MFXVideoENCODE_EncodeFrameAsyn API ,
or how to invoke this function in any place?
There is no body invoke this function in all Intel Media sample ?

Thanks!!

Lance

Hi Lance,

As for your first question, the EncodeFrameAsync function is called in sample_encode, you may check it out.

But the feature of key frame insertion, according to Media SDK developers, is not yet supported in Media SDK 2.0/SandyBridge encoders - this is a limitation. It will be available only starting with next generation of Media SDK.

If you represent a company could you please contact us via private post - so we could discuss schedules/plans/features in more details.

Regards,

Nina
