rtspsrc plugin problem

[chenjeff622]

this is my code .
####################################################################
Element src = ElementFactory.make("rtspsrc", "src");
src.set("location", "rtsp://XXXXXXXXXXXXXXXXXXXXXXXX");
src.set("latency", 100);

    Element decode = ElementFactory.make("decodebin", "decode");
    Element sink = ElementFactory.make("autovideosink", "sink");

    pipe.addMany(src, decode, sink);
    Pipeline.linkMany(src, decode, sink);
    pipe.play();

    Gst.getExecutor().schedule(Gst::quit, 60, TimeUnit.SECONDS);
    Gst.main();

####################################################################
it always show Exception:
(java.exe:16476): GStreamer-CRITICAL **: 19:13:22.985: gst_event_set_seqnum: assertion 'seqnum != GST_SEQNUM_INVALID' failed.

when i use commandline below. it display correct.
gst-launch-1.0.exe rtspsrc location="rtsp://XXXXXXXXXXXXXXXXXXXXXXXX" latency=100 ! decodebin ! autovideosink

You can't link a decodebin to the sink in this way. You need to listen for the pads to be added. This is handled for you if you use the CLI, or using the Gst::parseLaunch methods. Otherwise check the code at https://github.com/gstreamer-java/gst1-java-examples/blob/master/src/main/java/org/freedesktop/gstreamer/examples/AppSrcToAppSinkExample.java#L174
