Caught a segmentation fault while loading plugin file libgstpython.so
Intro
I'm trying to launch a pipeline using a python plugin (mask
):
videotestsrc ! videoconvert ! mask name=mask effect=gray shape=ellipse ! videoconvert ! gdppay ! tcpserversink host=0.0.0.0 port=5555
but get sometimes the error
ERROR: Caught a segmentation fault while loading plugin file:
/usr/lib/x86_64-linux-gnu/gstreamer-1.0/libgstpython.so
I.e.: at random it either runs or aborts with this error.
When I use the flag --gst-disable-segtrap
it always works, i.e. it does not only launch the pipeline correctly even all the rest of my code works. But my understanding is that the purpuse of this flag is to support debugging, not to use it for normal operations.
With gst-inspect-1.0 mask
everything looks ok.
Also using gst-launch-1.0
to launch the pipeline works correctly.
I can launch this pipeline with a simple python program using Gst.parse_launch
. Also with the Java binding (gst1-java-core
1.4.0
) I can launch it with Gst.parseLaunch
in a simple main
function.
The program that causes the problem is a multi-threaded webserver using ThreadPools on the JVM, that at a certain moment calls Gst.init
followed by Gst.parseLaunch
in a synchronous blocking style in the same thread (no other calls to Gst
yet), while the rest of program running on the JVM has no interaction neither with Gst
or python
. This code sometimes triggers the issue and sometimes works correctly.

ERROR: Caught a segmentation fault while loading plugin file:

So far as I can understand this logging:
Gst.init
is successful.
The call Gst.parseLaunch
from JVM to Gst start normal, the pipeline description is parsed and then the plugin libraries get loaded, but loading libgstpython.so
fails. Before I share logs using gdb, both succesfull and failure case. My server launches the initialization of the web app and the launch of the Gst pipeline in parallel. I observe that in the failure case a "epollEventLoopG" hit Catchpoint 1
is logged while in the successfull case it is not. It looks like in the successfull case the gst pipeline is launched before the http server (netty) starts its own threads.
Some version details:
-
Ubuntu 22.02 running Virtual Box 7.0 on macOS 12.6.5.
-
openjdk version "1.8.0_362"; used JVM options
-Xms2024m -Xmx4096m -Xss4M
-
Latest gstreamer1.0 libs installed with apt-get (incl gstreamer1.0-python3-plugin-loader)
-
Python 3.10.6 (installed via apt-get, no other python installed)
-
mask.py code uses python3-numpy and python3-opencv (both installed with apt-get)
-
Using PyGObject==3.44.1 installed via pip; the problem also occured with the latest version available on apt-get, which is older and caused additonal warnings (which are resolved using 3.44.1).
The web-server implementation is based on netty, as you can see in my (partial) classpath:
