This tells you that the video part of the pipeline is not connected at
the end ...

... and this says that there is no video stream detected here. So the
problem is unrelated to the Decklink card but either there is no video
stream inside the MPEG-TS container or we fail to detect it for some
reason.

In case of the latter, please file a bug with a test case and a stream
dump to reproduce the problem.
