Screen crashes during live streaming (black screen or white screen)
sometimes screen crashes during live streaming. In Wirecast is screen black or white. On YouTube is last frame of video. Audio continues normally. Do you mind what’s the problem? Is it in program or capture card?
Windows 10, Wirecast 7.7, Blackmagic Design DeckLink Duo 2, latest driver.

Version numbers are important. A week ago the latest driver was 10.9.9 and Blackmagic pulled that it seems and now it's 10.9.7 again. Always include version numbers as people are often mistaken over what "latest" is.

But that doesn't sound like a crash. Please explain in more detail what is happening. Explain as if you wanted someone to follow the same steps and describe exactly what you do and what the results are.
If Wirecast Live Broadcast Area (is that "screen"?) goes black or white that might be a source issue or it might be a GPU issue. I'd like to help but it's not clear what you're doing at the time. If you can't describe please post a screen shot.
For Blackmagic cards you may want to test in their Media Express to see if it's working. Maybe a bad card or a bad cable.Reply
My BMD driver is 10.9.7.
This issue happens only sometimes and not in the beginning of broadcast. Broadcast starts correct. Then it crashes = Live area in Wirecast is full black or full white (case to case different). I sent you PM how it looks like on YouTube. Sound continuous though it comes throw same SDI input as screen. I often stream more broadcasts simultaneously in different Wirecatst windows. If this issue happens, all are crashed. If I restart Wirecast program, it will repair screen and I can continue in broadcast.
My GPU is AMD FirePro W2100. If found, that there is older GPU driver, so I try update it. Maybe that’s the issue.Reply
Jan Kriz It's also possible there's an issue with the DeckLink Duo2. It might be interruption of loss of signal.
Do make sure the OS and GPU driver is up to date.
You may want to try a test in Media Express and let it run for an hour or so to see if fails there at some point.
Another test would be to take the DeckLink Duo out of the picture entirely and test with another source even if it's just a webcam. That will determine if it's specific to the DeckLink Duo.Reply
