VLC errors when running Monteray under UTM VM

[filbe]

Hi,
Thanks for a great product!

A low priority issue -

I bought a new Mac, and now find so much of my old software does not work.
I like to test new software in a Virtual Machine - only UTM seems to work fairly well.
Running Monterey 12.6 in UTM under host also running Monterey 12.6; VLC is version 3.0.18.

Video's work fine on the host - get sound but jumbled video on VM. The debug log repeats the following many times:
main debug: looking for text renderer module matching "any": 3 candidates
macosx debug: Activated assertion NoIdleSleepAssertion through IOKit (36583)

Maybe failing because UTM does not yet support required drivers etc?

Thanks again for your great work!

Have a merry Xmas

The OpenGL context cannot be created which is probably due to a bug or limitation in the UTM graphics card drivers.

Thanks Felix.

It seems UTM on MAC M1 chip does not yet support OpenGL.

Yet Quicktime player works fine. Can VC use the same video drivers as Quicktime?

We need to do a Metal-based video output instead of OpenGL. We might do it for version 4 of VLC also to support HDR rendering correctly.
