<div dir="ltr"><div class="gmail_default" style="font-family:verdana,sans-serif">Hello, I have a Flask application running on Gunicorn that creates a new GStreamer pipeline on a Start() API request (and sets the pipeline to NULL on a stop() request) The GStreamer pipeline operations are encapsulated in a class, and a new instance of the class is created for each Start API invocation, and its reference is deleted on the stop() API invocation. The basic flow is as such - Start API - * Initialize class * GObject.threads_init(), Gst.init() (and other members) * Create new Gst.Pipeline, Gst.Elements, and set pipeline to PLAYING Stop API - * Send Gst.Event.EOS to the pipeline * Set Gst.Pipeline to Gst.State.NULL I have noticed that with repeated start/stop invocations, the process has a lot of orphan gstreamer threads. I have tried to unref the pipeline, but then I get strange segmentation faults in other parts of my application. Does anyone have any pointers as to what I can try here? The python tutorials don't do any explicit de-initialization steps. Thanks, Vineet </div></div>
