    Add keyframe index metadata
    Used to facilitate seeking; particularly for HTTP pseudo streaming.
     1. read live streaming or file by sequence
     2. if use add_keyframe_index option, add a mark flag at the position,
        use to insert new context at the last step.
     3. add the keyframes *offset* and *timestamp* into a list
     4. if use add_keyframe_index option, shift the metadata data from
        mark flag offset
     5. insert the keyframes *offset* and *timestamp* from the list by
        sequence
     6. free the list
     7. end.
    
    Add FATE test case;
