MSI GTX 660Ti
Short description of error
In Blender VSE, when rendering a video with AAC as audio codec for output, the rendering fails with an "Unsupported channel layout" error from ffmpeg.
Exact steps for others to reproduce the error
The following archive contains a simple project. Rendering it with AAC audio codec output will fail with :
[aac @ 0x7f49e48cba00] Unsupported channel layout
NB: This bug was actually discovered months ago when ffmpeg 4.0 was pushed on Manjaro (and Arch): https://bugs.archlinux.org/task/59828
