How to destruct a pipeline??

[akaChella]

Hi all,

I have 2 pipelines. One is to play the video file locally and the other is to play the video and stream the audio.

I am constructing one of the pipeline at a time and is working fine.

Now i want to destroy the pipeline whatever has been constructed previously (say pipeline 1) and want to create the other pipeline (pipeline 2) during run time.

I have used gst_deinit() to destroy the pipeline.

and then initialised the gstreamer using gst_init() and later constructed the other pipeline.

But everytime it says, it is unable to construct the source element. i.e, gst_element_factory_make () returns -1.

Any idea on this issue???

You should not call gst_deinit to destroy the pipeline, to destroy the pipeline call:

gst_element_set_state (pipeline, GST_STATE_NULL);

and then

g_object_unref (pipeline);
 

and then initialised the gstreamer using gst_init() and later constructed
the other pipeline.

No need to call gst_init more than once.
 

But everytime it says, it is unable to construct the source element. i.e,
gst_element_factory_make () returns -1.

And actually, you shouldn't call gst_deinit unless you are are not going
to use gstreamer anymore during that program execution.
