Gstreamer operations not permitted on latest container builds

[jxs]

Hi, running the 2022-08-09T14-21-00Z-prod container and invoking Gstreamer outputs the following errors:

ERROR     GST_PLUGIN_LOADING gstpluginloader.c:442:gst_plugin_loader_try_helper: Spawning gst-plugin-scanner helper failed: Failed to close file descriptor for child process (Operation not permitted)

GStreamer-WARNING **: 10:44:03.965: 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.

GStreamer-WARNING **: 10:44:04.256: Failed to load plugin '/usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstxvimagesink.so': libXv.so.1: cannot open shared object file: No such file or directory

GStreamer-WARNING **: 10:44:04.316: Failed to load plugin '/usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstfluidsynthmidi.so': libfluidsynth.so.3: cannot open shared object file: No such file or directory

GLib-ERROR **: 10:44:04.323: file ../../../glib/gthread-posix.c: line 1339 (g_system_thread_new): error 'Operation not permitted' during 'pthread_create'

probably is reason for #24 ?

It's better to not rely on the timestamp in the image tag, because recent builds not always the latest.

Operation not permitted can be fixed by running container with privileged flag.
