Lock up with multiple GPU H.264 records?

Bugs
1

I’m seeing fairly consistent crashes with multiple movie out tops using the Nvidia GPU codec. Is that a known problem?

It happens if more than two or so records start at the exact same time.

Touch: 58910
Nvidia: 354.42, Quadro M6000
Also have four SDI inputs into a Quad Decklink card (v 10.5.1)

I’d start by upgrading your graphics drivers. Does that help?

Ha, that was an upgraded driver that I put on some other servers! Let me check if there is a newer.

Nvidia 361.91, and it’s a K5000, not an M6000, but still crashes when three or more records start. Here’s a fairly minimal test file. After three or four record - wait 4 seconds, pause, repeat cycles it locks up.

Can someone confirm or deny this is a bug? Any way to see whether Touch is locking up or somewhere in the OS or driver?

Confirmed that we can reproduce this. Will look into it this week.

Great, thanks.

I spent some time on it and reported the bug to Nvidia. The crash is occurring in their .dlls.
Tried to do things differently to see if I can work around the crash, but not luck…

Ok, thanks. I think multiple software mp4’s work ok, so that’s something.

Can you pin down when bug happens? Is it something I could avoid by spacing things out?

For me it seems to happen more if I hammer the record button. So it’s possible spacing them out a bit would avoid it.
