+- file/stream layout
+  - from every element we'd like to know what data is processes, what is pushed

+      gsize length;         // in bytes
+      gboolean known;       // or an enum: handled, skipped, unknown

+      gchar *description;   // long description or NULL
+      enum block_type type; // meta, audio, video, text, ...
+    };
+    - offset is not neccesarily easy to determine for later elements, not sure
+      if we can make it relative
+  - elements could emit messages with this info
+    - need a common way to enable it ("post-stream-layout" property)
+  - we would need a cairo custom widget to draw a table
+    - one row per element
