Having multiple inputs often causes "Most likely this is a multi-threaded client and XInitThreads has not been called" about gst1-java-core HOT 5 CLOSED

Please provide information on your OS, Java version, JNA version, native GStreamer version, gst1-java-core version etc. And ideally a simple code example that illustrates your problem, or at least a description of the pipeline you're using and the elements in it. Is it possible to recreate the pipeline on the CLI with gst-launch and if so does it work there?

Thanks!

OpenSUSE with Kernel 4.20, OpenJDK 8, JNA 4.5.0, GStreamer 1.14.4, gst1-java-core 0.9.2. I can provide a command line version for gst-launch on tuesday when I'm back in my office, but here's the entire pipeline in both table form and with a graph below it: https://lyrion.ch/opensource/repositories/videocapture/doc/trunk/config.html#org51f77d1(the column "Settings" refers to GStreamer's "Properties", and "Appcaps" is intern stuff from my program, irrelevant here)

Here is the CLI version:

gst-launch-1.0 \
    compositor name=mix sink_1::xpos=641 sink_1::zorder=1 ! queue ! autovideosink \
    rtspsrc location=rtsp://root:[email protected]/axis-media/media.amp latency=200 ! \
    "application/x-rtp, media=(string)video" ! decodebin sink-caps="video/x-raw" ! queue ! mix. \
    rtspsrc location=rtsp://root:[email protected]/axis-media/media.amp latency=200 ! \
    "application/x-rtp, media=(string)video" ! decodebin sink-caps="video/x-raw" ! queue ! videocrop left=640 ! queue ! mix.

@zilti thanks! Can you update to gst1-java-core 0.9.3 and JNA 4.5.2? I'm not sure either will fix this, but be good to confirm that latest stable releases still break.

Are you using a Java UI? If so, try without. If not, maybe try opening a Swing window (and making sure it's opened) before running the pipeline.

Can you share the code you have to set up the pipeline anywhere? What thread(s) are you setting up the pipeline on?

Closing as no further comment. Please retry with 0.9.4 and JNA 5.2, and get back if this is still an issue and I'll reopen.
