Android gst_parse_launch using

[Peter Hafner]

Sebastian,
Thanks for helping here.
With this pipline, I was testing my syntax on the pipline.
Here, a pipeline without failure. Special the part for sprop-parameter-sets
was hard to find out.
/data->pipeline = gst_parse_launch("udpsrc port=4000 
caps=\"application/x-rtp, media=(string)video, clock-rate=(int)90000, 
encoding-name=(string)H264, 
sprop-parameter-sets=(string)\\\"Z0KAHukBQHpCAAAH0AAB1MAI\\\\=\\\\=\\\\,aM48gA\\\\=\\\" 
\" ! rtph264depay ! avdec_h264 ! decodebin ! autovideosink", &error);//
/
Now this pipeline is parsed without any syntax failure message :-)
If I have the original pipeline
/data->pipeline = gst_parse_launch("playbin", &error);/
everything is working.
after changing to "my" pipeline, and starting the app, I get
/gst_video_overlay_set_window_handle: assertion `GST_IS_VIDEO_OVERLAY 
(overlay)' failed/
With the latest patch

-    gst_x_overlay_set_window_handle (GST_X_OVERLAY (data->pipeline), 
(guintptr)data->native_window);
+    gst_video_overlay_set_window_handle (GST_VIDEO_OVERLAY 
(data->pipeline), (guintptr)data->native_window);

We changed from GST_X_OVERLAY to GST_VIDEO_OVERLAY, but again, the 
default pipeline is running, so I think, this will not be the problem.
