The main difference is that gst_launch was written by some really smart people and they knew what was needed for each element. You probably don't have your pipeline implementation optimized. It is more work to implement a pipeline in C, but you do get the same performance, more flexibility and a more robust application. Post your pipeline and someone can make some suggestions to help. <div class="gmail_extra"> <div class="gmail_quote">On Jul 18, 2016 9:43 AM, "nagendra sarma" <<a href="mailto:nagendra.bankupalli@tessolve.com">nagendra.bankupalli@tessolve.com</a>> wrote: <blockquote class="quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> hi all i have a complex gstreamer pipeline with TEEs, Encoders with mpegts etc the pipeline is working without any issue. if i put same pipeline into application i saw some frame losses (not in the case of gst-launch-0.10) i enabled debug level=3 but i could not get any error; i would like to know 1. is there any difference between application and pipeline (gst-launch) in performance ? 2. any special care should take care while writing application ? 3. is it normal ? (application performance is always less than raw pipeline performance ?) please let me know your views regards nagendra -- View this message in context: <a href="http://gstreamer-devel.966125.n4.nabble.com/gstreamer-application-versus-gst-launch-pipeline-tp4678733.html" rel="noreferrer" target="_blank">http://gstreamer-devel.966125.n4.nabble.com/gstreamer-application-versus-gst-launch-pipeline-tp4678733.html</a> Sent from the GStreamer-devel mailing list archive at Nabble.com. _______________________________________________ gstreamer-devel mailing list <a href="mailto:gstreamer-devel@lists.freedesktop.org">gstreamer-devel@lists.freedesktop.org</a> <a href="https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" rel="noreferrer" target="_blank">https://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </blockquote></div> </div>
