    Description

      using decodebin3, rtsp streams are not working anymore.

      steps to reproduce:

      • run rtsp-test-server.rtsp-test-server (from snapstore)
      • minimal-player rtsp://localhost:8554/bars

      observed behaviour:

      "    15.291 - minimal-player: qt.multimedia.player - received bus message: error, Source: typefind, Error: Could not determine type of stream. (../../dev/gstreamer/subprojects/gstreamer/plugins/elements/gsttypefindelement.c(1025): gst_type_find_element_chain_do_typefinding (): /GstPipeline:playerPipeline/GstURIDecodeBin3:decoder/GstURISourceBin:urisourcebin0/GstParseBin:parsebin0/GstTypeFindElement:typefind)"
      "    15.291 - minimal-player: qt.multimedia.player -     error Could not determine type of stream. (../../dev/gstreamer/subprojects/gstreamer/plugins/elements/gsttypefindelement.c(1025): gst_type_find_element_chain_do_typefinding (): /GstPipeline:playerPipeline/GstURIDecodeBin3:decoder/GstURISourceBin:urisourcebin0/GstParseBin:parsebin0/GstTypeFindElement:typefind)"
      

      gst-launch with playbin3 works fine, though:

      gst-launch-1.0 playbin3 uri=rtsp://localhost:8554/bars
      

      the decodebin(2) implementation did not have this issue

      separate issue when using rtsp-server-perl to serve a stream:

      • ffplay works: ffplay rtsp://localhost:8888/mystream
      • gst-launch times out: gst-launch-1.0 playbin3 uri=rtsp://localhost:8888/mystream
