Blender mixdown broken
I'm submitting a...
- [x] Bug report.
- [ ] Feature request.
Bug report
What is the current behavior?
Mixdown crashes:
~ WARNING:mixdown: Something went wrong when calling command - SKIPPING.
The problem probably lies on the Blender side (bug report filed), since Blender "Render Audio" feature gives this error:
terminate called after throwing an instance of 'aud::FileException'
what(): File couldn't be written, audio encoding failed with ffmpeg.
What is the expected behavior?
Mixdown should not crash and produce an audio file instead.
Tell us the steps to reproduce the bug, and if possible share a minimal demo of the problem.
Make sure you have Blender 2.92.3 and try rendering a mixdown with bpsrender.

But probably a good idea to have the bug listed here as well if someone is looking at what's wrong.
I tried also with the new Blender 3.0 Alpha and the same error there. With Blender 2.83.15 feature still works, but I'm not sure which version broke it.
Thanks but according to your report, it has to do with Blender? If running it from inside Blender fails, then all this script does is asking blender to make a mixdown, so we can't fix it on our side.
Yep. I just thought maybe it'd be nice to have the bug listed here as well so people can find the cause more easily. At least it took quite a while for me to figure out the root cause maybe lies in Blender itself.
