Hello, I share for information the problem and solution I encountered why trying to run spice-server gstreamer encoding on Fedora30: > warning: GStreamer: External plugin loader failed. This most likely means that the plugin loader helper binary was not found or could not be run. You might need to set the GST_PLUGIN_SCANNER environment variable if your setup is unusual. This should normally not be required though. this was due to seccomp syscall filtering, as my (virsh) VM was running with this option: > -sandbox on,obsolete=deny,elevateprivileges=deny,spawn=deny,resourcecontrol=deny I don't know what is the clean way to solve it, but patching qemu to force "-sandbox off" gets rid of the codec issue regards, Kevin _______________________________________________ Spice-devel mailing list Spice-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/spice-devel
