We are implementing DVR functionality, fast playback, for example 2x or 4x speed;
How MFXVideoDECODE_SetSkipMode should be used to achieve DVR-like fast forward behavior?

Hi Alex,
The purpose of the SkipMode call is to tell the decoder to skip decoding of more or less frames (in essence this means skipping B frames, then P frames and eventually only decode I frames if skip distance is large).
SkipMode can be called at anytime after initializing the decoder. SkipMode can also be called several times to gradually increase or decrease the # of skipped frames.
We do not provide sample code for this specific feature. But as described above, using it is a matter of just calling the function (one line of code). The Media SDK reference manual have some additional details.
Example: SetSkipMode(MFX_SKIPMODE_MORE);
Regards,
Petter
