For instance: `rtspsrc location = rtsp://192.168.0.61:8554/quality_h264 latency=0 ! rtph264depay ! h264parse ! video/x-h264,stream-format=avc ! queue` What is `video/x-264` for? The pipeline seems to work even without it. Is the element optional?<br /> <br /> Thanks<br /> <br /> John</div> </div> </body> </html>
