You should provide a default implementation that just returns 0 so that
mssdemux and hlsdemux won't crash/assert.

+  if (GST_BUFFER_PTS (buffer) != GST_CLOCK_TIME_NONE)
+    GST_BUFFER_PTS (buffer) += offset;

How about moving this to when the PTS is set on the buffer a few lines above?

Makes easier to read the code as the PTS is set only once and is not modified
anymore.

You can also only call the get_presentation_offset function inside the
'first_fragment_buffer' if as it would only be used there.
