mpegts gdp test file

https://cgit.freedesktop.org/gstreamer/gstreamer/commit/?id=63f6f05d66537877365a1099ac176dc3afbb9f6b introduced variable GstStream. This is added in the stream-start event by tsdemux.

First, running the command:
gst-launch-1.0 -v filesrc location= mpegts.gdp ! gdpdepay ! tsdemux ! identity silent=false ! ac3parse ! gdppay ! filesink location= eac3.gdp

We can see the variable stream (stream=(GstStream)"\(GstStream\)\ stream1"):
E (type: stream-start (10254), GstEventStreamStart, stream-id=(string)fd91ddf0b44530850315c637f356514d:1282/000000e6, flags=(GstStreamFlags)GST_STREAM_FLAG_NONE, stream=(GstStream)"\(GstStream\)\ stream1", group-id=(uint)0;) 0x75b02450

Then trying to gdpdepay eac3.gdp:
gst-launch-1.0 -v --gst-debug=*gdp*:5 filesrc location= eac3.gdp  ! gdpdepay ! fakesink silent=false

We have:
Could not parse payload string: GstEventStreamStart, stream-id=(string)fd91ddf0b44530850315c637f356514d:1282/000000e6, flags=(GstStreamFlags)GST_STREAM_FLAG_NONE, stream=(GstStream)"\(GstStream\)\ stream1", group-id=(uint)0;

Removing the stream variable makes it working.

It seems that something is missing in gstvalue or gststructure ?
