I am pretty inexperience with moving raw video data in between bufffers. Does anyone know what methods are good for completing this task?  Below is a sample of my code to make it a little more clear as to what I am doing exactly.  Thank you in advance. /* This method is called for each video frame that arrives */ HRESULT STDMETHODCALLTYPE VideoDelegate::VideoInputFrameArrived(IDeckLinkVideoInputFrame *pArrivedFrame, IDeckLinkAudioInputPacket *pArrivedAudio) {                       fprintf(stdout, "Video frame arrived.\n");         /* This method gets the raw video frame bytes and stores them in a void* temp_data */         pArrivedFrame->GetBytes((void**) &temp_data);         /* Here is where I need to take temp_data, and somehow move it into the data portion of a GstBuffer video_buffer */         /* After I have the data in video_buffer, I will push it to the appsrc element */         gst_app_src_push_buffer(GST_APP_SRC(appsrc), &video_buffer);         return S_OK; } </BODY> </HTML>
