dashdemux/mpdparser: problem with German DVB-T2 DASH Preview

[Juergen Sachs]

Hi,
there is a problem in the mpdparser coming up with some streams from the German DVB-T2 DASH preview streams. When playing such stream I get an error
  >> gstmpdparser.c:1645:gst_mpdparser_parse_mult_seg_base_type_ext: segment has neither duration nor timeline
The manifest contains SegmentTemplate nodes both in the AdaptationSet and in the Representation nodes. The SegmentTemplate in AdaptationSet does not contain a duration attribute and therefore the parser bails out (without examining the sub-nodes).

  <AdaptationSet segmentAlignment="true" bitstreamSwitching="true" maxWidth="1280" maxHeight="720" maxFrameRate="50" par="16:9" lang="und">
   <Role schemeIdUri="urn:mpeg:dash:role:2011" value="main"/>

I have fixed this issue locally in gstmpdparser.c and my question is how to get this patch in the master. What is the correct way to do this
- do I need to fill a bugzilla report first, what are the next steps after
- shall I send the patch to someone

Kind regards

Please create a bug in Bugzilla and attach your patch and any details you have about the issue. If possible, your patch should be in "git format-patch" format and against git master.
