As you can see the videoReferences with playerTypes dash264 and dashhbbtv point to MPD manifests that are currently not handled by youtube-dl.

i will add extraction for dashhbbtv mpd manifest.
the second mpd manifest won't work untill we add support for SegmentBase in mpd manifests.

i will add extraction for dashhbbtv mpd manifest.

it works but it will cause sorting problem, we should wait untill dash formats sorting fixes.
