Hello,
we have exactly the same problem as stated here: https://groups.google.com/g/kurento/c/kN97ow37piU

It is crazy that after 8 years there still is the same issue in Mixer that makes it basically unusable - or at least I do not see any working examples around.

We just need do route video 1-N and mix sound N-N. Composite is no go for us as it has fixed resolution output and we need best possible quality.

Unfortunately there is no stacktrace, just this:

We are using official 7.0.1 build. I would be even willing to pay for the solution as this is now critical for our product and it seems that only way forward would be to switch to something else than KMS, which would introduce large delay in the project.

Thank anyone for looking at this.

Btw, we have been trying to use the -asan build, but the docker images won't start due to missing Boost libraries.
