The tradeoff is, of course, that you give up a lot of flexibility. If your pipelines are fixed (do not grow or shrink) in their lifetime Gstd may help you. On the other hand, if you have a dynamic pipeline, with more sophisticated stream handling, Gstd definitely falls short.</div><div class=""><br class=""></div><div class="">We like to think of Gstd as a gst-launch-1.0 under steroids. Besides creating and playing pipelines, you can query/set properties at runtime, check for bus messages, listen to element signals (limited though), etc… Again, I’d like to insist in that it’s not suitable for all applications. Internally, we handle both approaches: for simpler, static media servers we use gstd, for complex highly dynamic media servers we use GStreamer API instead. Another big use we give to Gstd is to automate testing. Since it is controlled via TCP commands, the test can be controlled from a host PC while everything is running on an embedded platform, for example...</div><div class=""><br class=""></div><div class="">Long story short, my rule of thumb is:</div><div class="">Whatever pipeline that can be built and played using gst-launch-1.0 can be properly handled by Gstreamer Daemon.</div><div class=""><br class=""></div><div class="">Michael</div><div class=""><a href="http://www.ridgerun.com" class="">www.ridgerun.com</a></div><div class=""><br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Aug 6, 2019, at 8:30 AM, Daniel Rossi <<a href="mailto:electroteque@gmail.com" class="">electroteque@gmail.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div style="caret-color: rgb(0, 0, 0); font-family: "Segoe UI"; font-size: 16px; font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none;" class="">I'm looking into this project to start and monitor for 24/7 receiver purposes.
