AVIs are broken with new FFmpeg
Writing .AVIs on Macs are broken. Here is how to replicate.
- Kitware nightly build, Mac (Catalina), ParaView-5.9.1-1531-g9ed12068.app, builtin server.
- Open can.exo. Apply.
- File/ Save Animation/ .avi/ take the defaults.
LOTS of error messages, and the .avi looks like trash. I will attach the .avi. Here is the top of the output dialog:

raise RuntimeError(msg)
RuntimeError: Polyfit sanity test emitted a warning, most likely due to using a buggy Accelerate backend. If you compiled yourself, more information is available at https://numpy.org/doc/stable/user/building.html#accelerated-blas-lapack-libraries Otherwise report this to the vendor that provided NumPy.
