I am not sure what would be the "proper" way to send this kind of information. The drawback is you would have to have metadata for every frame, but it would at least hopefully be fairly synchronized. I have seen datastreams in the wild, just haven't had the need to implement one myself. So there is probably a cleaner implementation. <div class="moz-cite-prefix">On 12/11/2019 2:24 PM, k4ustav wrote: </div> <blockquote type="cite" cite="mid:1576103055957-0.post@n4.nabble.com"> <pre class="moz-quote-pre" wrap="">Thanks Michael for your reply. I am trying to send two parallel streams. One video stream and another metadata stream. The metadata stream contains metadata for each video frame, for example, inference data for each video frame. The framerates for both the streams are same. To implement this, I thought to send the metadata through normal sockets and video stream through the GStreamer RTSP server. To sync the video frame and per-frame metadata at the client I am planning to use timestamp. Because of this, I am planning to send timestamps along with the video frame. But if you can suggest a better way or example to do this, it would be really helpful. -- Sent from: <a class="moz-txt-link-freetext" href="http://gstreamer-devel.966125.n4.nabble.com/">http://gstreamer-devel.966125.n4.nabble.com/</a> _______________________________________________ gstreamer-devel mailing list <a class="moz-txt-link-abbreviated" href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a> <a class="moz-txt-link-freetext" href="https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel">https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </pre> </blockquote> </body> </html>
