Unable to build pipeline: no element audiotestsrc

[dhruv-jindal]

I have trying to run an iOS Swift Project with GStreamer library. I am
getting the following issue whenever I try to go get_parse_launch of
audiotestsrc.

Unable to build pipeline: no element "audiotestsrc". Any idea what am I
doing wrong here?

Code :

GstElement *pipeline = gst_parse_launch("audiotestsrc ! audioconvert !
audioresample ! autoaudiosink", &error);

I haven't programmed gstreammer with C++.


The plugin audiotestsrc is part of gst-plugins-base, so you need to have
gst-plugins-base installed. You can check if the plugin is available in your
system with:

gst-inspect-1.0 audiotestsrc

Solved the issue. I just needed to include gst_ios_init.h and gst_ios_init.m
files in my iOS Project.
