Hello folks,
I’m building a video loop machine with 6 sdi output from a DeckLink Quad 2. As a machine, I’m using an HP Z840 with Nvidia Quadro K5200, and a Linux operating system (Ubuntu 24.04). Do you recommend using this version in production, or is it not stable enough? If not, what is the recommended version of CasparCG known for stability? Also, any recommended Decklink Quad 2 driver that is stable enough for the CasparCG? I remember not all versions of the DeckLink are stable with CasparCG. Please, suggestions and advice….
Best,
Andi
I have been using it on ubuntu in production for a while and there is still a core dump that happens periodically. Normal playout without extra ffmpeg consumers works and only crashes every few months. Extra things or high utilization and it isn’t as stable. Are you running 6 HD or SD outputs? If HD, I would highly recommend a significant CPU and GPU upgrade. I am only able to run about 2 channels with a similar age 16 core dual socket server and p4000. The machine will run 4 channels with late/missed frames fairly well from a utilization perspective and may work better when I eliminate the interlaced HD source files. Decklink is rock solid, and I am currently running a TV station 24/7 with it with minimal issues. Hopefully I can characterize and solve the remaining issues soon but I would give it a try.
I think it would be helpful if people could post their default multichannel config/use case along with hardware specs as that would be very informative for those of us that are considering upgrading/building production machines also.
Hello zcybercomputing,
Yes, but how can you put into production something that crashes all the time, with no explanation? I remember version 2.4 was much more stable, and it didn’t crash too often. I was running in record mode for 3-4 months with 2 channels and an older machine, the HP Z800. I can see that I’m not using more than 30-40 percent of the CPU with this Z840 for 2 channels, and it doesn’t use more than 60 percent with 4 channels. Is this a problem only on the Linux system, or is the same thing happening on Windows as well?
