Server: Mixer perspective on routed layer

[RuneFog]

Expected behaviour

mixer perspective on a routed layer should be treated as one source

Current behaviour

mixer perspective on a routed layer is applied on each individual layer in the origin channel

Hi

Tried this and can confirm that it behaves the same in 2.3
Have you tried if it behaves the same in 2.1?

/olle

[baltedewit]

I'm not sure how that build ended up in that folder on the build server, but your logs seems to imply you're actually running server 2.3 beta 1 and not server 2.2

This sounds a lot like a regression caused by zero delay channel routes (cc @scriptorian)

[ronag]

I'm not sure how that build ended up in that folder on the build serve_

My bad, that was actually 2.3 beta1
But I get the same result in 2.2.
(Must have mixed up the .zips)

The issue is not present in 2.1.x latest build

[jesperstarkar]

@5opr4ni could this be the new bug you mentioned during the TSC meeting?

[ronag]

At this point I think we should just revert the zero delay commit...

[jesperstarkar]

@ronag this bug seems to track back as a 2.2 regression and does not look to be related to the new routing.

[jesperstarkar]

Tested and confirmed to be the same bug in 2.2 #f0d65d66

[Julusian]

I suspect this will be some incorrect maths when combining the transforms in which case it could also be an issue in 2.1 with the scene producer but when nesting a scene inside another scene.

Is this a blocker for 2.3.0? I dont think I will have time to look at it for then

[dotarmin]

@ronag I'm not sure how that build ended up in that folder on the build serve_

A provisioning didn't go as expected. Fixed now and a new build is available for v2.2.x branch and same for v2.3.x-lts branch.

[5opr4ni]

@5opr4ni could this be the new bug you mentioned during the TSC meeting?

Nope! My issue has to do with this command MIXER 1-8 KEYER 1. I will come back with an issue when I have made a proper description.

No!

[dotarmin]

I agree with @5opr4ni, it's not a blocker because the same behaviour exists in v2.2. However i would like to see it fixed in v2.3.1 LTS and have it as a part of the LTS version.
