I faced problem with memory management with GES. I have a program which plays a list of video files. You can add files to the list and play it. User can replay the list without shutting the program down. Video files list elements are basic C strings and I build timeline from scratch whenever I start playing my videos list. The problem is that GES stores clips into the memory and does not release it after all the timeline is played. That is, after each time I play my timeline, the total consumption of the RAM my application uses just accumulates, for example after the first time I play my timeline my application RAM consumption is 100MB, after I play it second time it doubles and it uses 200mb. There must be a problem with memory management. I use assets, I unref them, I use static timeline and pipiline, maybe that is the cause? do I need to unref timeline and pipeline? I use 	g_object_unref (pipeline); g_object_unref (timeline); but it does not help The code below represents my problem:

#include <ges/ges.h>
#include <stdio.h>

static GESTimeline *timeline;
static GESPipeline *pipeline;

int
main (int argc, char **argv)
{
	gchar *firstFileAddress = "C:/videoSamples/sample2.mkv";
	gchar *secondFileAddress = "C:/videoSamples/sample2.mkv";
	int a = 0;
  	gst_init (NULL, NULL);
  	ges_init ();

	printf ("check process memory consumption before playing video files(enter any number! and press enter) \n");

	scanf("%d",&a);
	// lets play first playlist
	if(1){
		GMainLoop *mainloop;
		timeline = ges_timeline_new_audio_video ();


		// Adding clips to the timeline
		if(1) {
			GESAsset *src_asset;
			GESLayer *layer;
			gchar *uri;
			GESUriClipAsset *asset;		

			layer = ges_timeline_append_layer(timeline);

			uri = gst_filename_to_uri (firstFileAddress, NULL);
			asset = ges_uri_clip_asset_request_sync(uri,NULL);
			src_asset = GES_ASSET(asset);
			ges_layer_add_asset (layer, src_asset, 0*GST_SECOND, 5*GST_SECOND, 2*GST_SECOND, GES_TRACK_TYPE_UNKNOWN);
			gst_object_unref (src_asset);
			g_free(uri); 
		}

		}
