In the context of the pipeline rtspsrc->rtph264depay->h264parse->appsink, which element sets the GST_BUFFER_FLAG_DELTA_UNIT flag? I read that a keyframe has a unique start code in the NAL unit. In that case, does that mean rtph264depay sets the flag?<br /> <br /> Thanks</div> </div> </body> </html>
