[gst-devel] Error getting component width

[Brian Michalk]

I'm getting the following error, even after I added set_caps functions.
gst_video_format_get_component_width: assertion 'width > 0' failed.

My transform:

static GstFlowReturn
gst_xyz_transform_ip (GstBaseTransform * base, GstBuffer * outbuf) {
   Gstxyz *filter = GST_XYZ (base);

   if (GST_CLOCK_TIME_IS_VALID (GST_BUFFER_TIMESTAMP (outbuf)))
     gst_object_sync_values (G_OBJECT (filter), GST_BUFFER_TIMESTAMP 
(outbuf));

   if (filter->silent == FALSE)    g_print ("I'm in.\n");

   guint8 * data = GST_BUFFER_DATA (outbuf);

   GstFlowReturn ret = GST_FLOW_OK;
   VSImage dest = filter->dest;

// ERROR HERE
   gint lwidth  = gst_video_format_get_component_width (filter->format, 
0, filter->dest.width);

   gint lheight = 
240;//gst_video_format_get_component_height(filter->format, 0, 
filter->dest.height);
   gint offset = 1; //gst_video_format_get_component_offset 
(filter->format, 0, filter->dest.width, filter->dest.height);

   return ret;
}
