EGL_NOT_INITIALIZED when Activity goes in onPause and the video source isn't valid

Wed Dec 23 07:52:22 PST 2015

Hi all, first of all thank to all for this great framework.
I have a problem in an Android application that use the same code of the
tutorial3 Android sample. My purpose is to display a http\mjpg stream from
an IP camera into a SurfaceView.
So I modified the pipeline creation in this way:
data->pipeline = gst_parse_launch("souphttpsrc location=
http://192.168.1.201/video.mjpg <http://192.168.1.201:10554/ipdoor.mjpg> !
jpegdec ! autovideosink", &error);
and the code works well.

I have the same identical code of the tutorial, unless for the fact that I
moved the SurfaceView creation: I attach and detach a Surface in a
FrameLayout when I press a button.

However I get a problem when I create the pipeline with a location that
doesn't exist or that isn't reachable. The application runs well until I
stay in the same activity: I can attach and detach the surface correctly
all times I want, but after that, if I send the Activity in the onPause
status, I have a crash.

I think the problem concerns the fact that the source isn't valid.

This is part of the log:
