Caspar CG & Windows 11

General
1

Hello,
Did someone already test CasparCG on Windows 11 ?
Do you have any feedback about it ?

2

Yes. It works just fine.

Thank you, Vimlesh!

It shouldn’t really be any issue considering windows 10 and 11 are not that far away.

yep i was using it the other day to do some template designs.
worked fine with 2.3.3-LTS

Thank you all.

I’m facing some problems, any time I start CasparCG it appears this messages.

TBBmalloc: skip allocation functions replacement in ucrtbase.dll: unknown prologue for function _msize
[2023-09-14 13:17:49.695029] [0x00003adc] [error]    0# 0x00007FF741BFB906

And if I type a command directly on the console it works perfectly, but if I use a external application come times it does not assume the commands even with defaul casparcg client.
Some times it receives the command and I need to go to the console an add several “enter/return” and then the command is assumed.

I tested with casparcg 2.3.3 stable and with the latest versions. My Windows 11 version is Windows 11 Pro Insider Preview, 23H2, 25947.1000.
I thing the first versions of Windows 11 it was ok, but stop working as it should some months ago.

Anyone is facing this and know how to resolve?
Thanks

Could it be because your windows version is a preview one ? Maybe, it will be fixed by microsoft in the released version.

Windows 11 got updated to 24H2. Started seeing this error.
Did @Gaspar find a solution to this?

10

Copied and applied TBB_MALLOC_DISABLE_REPLACEMENT=1 env variable from this Blender forum post. Seems to have fixed this, at least the error message is gone.

Would you mind explaining where and how to set this variable?

12

Sure. Windows System Properties > Advanced System Settings > Environment variables. I put that in System Variables section. There is also User variables section.

24h2. Has given me a lot of greiff. In other streaming and live event applications as well as CasparCG. Last moth i reinstalled windows on 7 production computer. There is a recent release of windows 11 - LTSB. It will only recive security updates and no feature updates. It was a nice breath of fresh air. To log in to windows with out all the trash i dont need or want.
If u use Rufus to install it you can set up all the windows account and credential suff in the install image. This allows headless michines with automatic login no account needed.

Any way preformance was a lot better for me across the board. If it is an option for you look in to windoes 11 LTSB.

You are referring to Windows 11 Enterprise Long Term-Servicing Channel (LTSC) correct?

15

Yep that is the one.
