We have bought 6 DeckLink Duo 2 capture cards. Each of them are installed onto a HPE ProLiant DL360 Gen9 Server. We can capture video from SDI1 and SDI2 on them using ffmpeg. However, SDI3 and SDI4 inputs failed after a few seconds every time while we captured video using ffmpeg when all 4 inputs were used. SDI3 and SDI4 worked fine when SDI1 and SDI2 are not used. SDI3 and SDI4 worked if SDI1 and SDI2 were not used.
Similar results happened on Media Express as well. The SDI3 and SDI4 input went black after a few seconds.
We have tried a Duo 2 card on a Dell Optiplex. All 4 SDI inputs were working simultaneously.
Is there anything we can do to get them work?
Thank you very much!
