Description
This is a crosspost of the following bug report: https://github.com/llvm/llvm-project/issues/107364
In short it seems that compiling ffmeg with -fveclib=mvec on Linux break the aac and vorbis decoder:
ffmpeg -i x.ogg x.wav -> x.wav sounds bad
ffmpeg -i x.m4a x.wav -> x.wav sounds bad
I imagine that the test suite should catch it.
Maybe you could help llvm devs to isolate a reproducible test case?
I've tested with ffmpeg 7.0.2
