Try just

  decklinkvideosrc device-number=2 connection=HDMI mode=11 !
videoconvert ! x264enc ! video/x-h264,stream-format=byte-
stream,profile=main ! ...


no need to specify a caps filter if you specify the mode already. Also
there's no "profile" field in raw video caps (you will need to put
filtercaps after x264enc to force a profile).

Note that I'm not sure if x264enc will handle interlaced input
correctly (there might be some code missing that looks at the incoming
video stream and configures the encoder properly for interlaced input).

Cheers
