[FFmpeg-user] capturing decklink "past duration too large" wrong pts ?

Hello,
I am trying to capture 4 different streams using 4 Blackmagic mini
recorders (to ProResLT) and in the second step to create a splitscreen
with those videos.
After arround 15 seconds while creating the splitscreen I get the message:
"Past duration 0.999992 too large"
The result is a nice splitscreen video which freezes after 15 seconds
(as soon as the error message shows up)
I also tried the option -vsync drop for the splitscreen encoding and I
made it past the 15 seconds barrier, but the video length is not correct.
I also tried -vf setpts with diffent options.
I asume it is a pts problem while capturing (playback using vlc for the
captured streams is fine) but so far I haven´t found any solution for
this problem.
Best
Joop
Following you can find my ffmpeg commands/console output:
ffmpeg -bm_v210 1 -f decklink -i "DeckLink Mini Recorder (4)@7" -vcodec
