How to assign a media sample as a key frame in MFT. RRS feed

  • Question

  • When we are developping DMO, we can assign a sample as a synchronization point by set the "DMO_OUTPUT_DATA_BUFFERF_SYNCPOINT"

    But when we are developping MFT, how can we assign a sample as a synchronization point? I can't find any functions in the IMFSample interface.

    Could you help me?

  • Set the MFSampleExtension_CleanPoint attribute on the sample:

        pSample->SetUINT32(MFSampleExtension_CleanPoint, TRUE);
