gst_unref_object GstElement*

[killerrats]

I created some GstElements but when I go to unref them in the end it says
"GStreamer-CRITICAL **: gst_object_unref: assertion '((GObject *) object)->ref_count > 0' failed"

I checked to see if its null and it isn't but don't understand why it says this. It's only saying about:

GstElement* RecBin,* source,* q1,* rtpdepay,* parse,* vtee,* q2,* audioRtpDepay
                                 ,* audioParse,* audioDec,* atee;
                GstElement* q3,* q4,* mux,* appsink;

that are in the class.

what I do is this steps:

1. setup gstelements
2. link them up
3. start to play
when I stop the pipeline
1. null pipeline, unlink them, remove pads
2. unref the gstelements (This is where it errors out)
3. unref pipeline.

videoRecClass.h

i just gave you the create and unlink and delete for the gstreamer pipeline.

VideoRecClass::Create_Pipeline();
void VideoRecClass::delete_pipeline();
bool VideoRecClass::LinkRtspRecPipeline();
bool VideoRecClass::LinkRtspSrcPipeline();
void VideoRecClass::UnlinkRecPipeline();
void VideoRecClass::UnlinkRtspSourcePipeline();
void VideoRecClass::UnreferenceRtspRecVideoData();

According to 2nd paragraph of description from https://gstreamer.freedesktop.org/data/doc/gstreamer/head/gstreamer/html/GstPipeline.html, all added elements are freed when pipeline is freed.

This is a good point to check first.

3. unref pipeline.

When you add an element to a pipeline, you give the pipeline ownership. No need to unref these elements, the pipeline will do that for you.
