decodebin3: regression handling streams without caps

Prep:

  • wget https://people.freedesktop.org/~tpm/samples/tearingtest.mp4

Does not work:

  • gst-launch-1.0 pushfilesrc location=tearingtest.mp4 ! decodebin3 ! fakesink
  • gst-launch-1.0 filesrc location=tearingtest.mp4 ! queue ! decodebin3 ! fakesink
  • gst-launch-1.0 udpsrc ! decodebin3 ! fakesink (receiving e.g. MPEG-TS)

Works:

  • gst-launch-1.0 filesrc location=tearingtest.mp4 ! decodebin3 ! fakesink
  • gst-launch-1.0 pushfilesrc location=tearingtest.mp4 ! decodebin ! fakesink (legacy decodebin)
