Problem with multiple tees in pipeline

[yoyosuper8]

Hi all, I'm having some problems with tee and I can't figure out why it
doesn't seem to work properly.
Please note that I'm working on Android devices. In my gstreamer pipeline, I
need to have two tees. One tee is for taking snapshots, the second tee is
for recording to a file. I'm also using valve to turn on/off each tee. Here
is what my testing pipeline looks like:

videotestsrc ! videoconvert ! tee name=snapshot ! valve name=snap drop=true
! jpegenc ! filesink location=/home/user/Desktop/pic1.jpg snapshot. !
eglglessink name=videosink

This simple pipeline I believe it should have the main branch which displays
the videotestsrc into the eglglessink and the second branch should save a
frame into a jpg file when the valve is set to drop=false.

When I push on a button, the valve is set to drop=false, but it does not
save a frame to a file. This is how I perform the update of valve:

    gelement_name = "snap";  // name of element
    gprop_val_name = "drop"; // name of property
    gProp_val = "false";         // new value to set in property

    // Get the element from the pipeline by using the element name
    GstElement *element = gst_bin_get_by_name (GST_BIN (pipeline),
gelement_name);
    
    if ( strcmp(gprop_val_name, "drop") == 0 )
    {
    	gboolean prop_val = FALSE;
        // if the property value is true, then send an EOS.
    	if ( strcmp(gProp_val, "true") == 0 ) {
    		gst_element_send_event(element, gst_event_new_eos());
    		prop_val = TRUE;
    	}
    	else {
    		prop_val = FALSE;
     	}

    	// Update property in pipeline.
	g_object_set (element, gprop_val_name, prop_val, NULL);
    }

However, if I remove the eglglessink name=videosink from the pipeline, the
above works. But with the eglglessink in the pipeline, the snapshot tee
doesn't work. Also, with eglglessink in the pipeline, I see the videotestsrc
in the screen, but it is a still image, it seems that all the other frames
are dropped, but in the log everything seems fine and no warnings or errors.

Am I missing something in the pipeline or am I using tee the wrong way?
Please help.

Andy
