My company-supplied MacBook has just been upgraded from High Sierra to Mojave, and now AC3 audio support for MPEG-2 video files seems to be at least partially broken.
In VLC or Premiere Pro the video plays perfectly, but there is no audio; in MPEG Streamclip the audio plays perfectly but the video is corrupted (but obviously Streamclip hasn't been updated in years so it's a minor miracle that it still works at all).
The fact that the audio doesn't work in VLC was a real surprise.
Do I need to persuade our IT department to install Perian for me? Does it even run on Mojave? I can't remember if it was installed when I had High Sierra, but I do know that .mpeg or .mpg files with AC3 audio played perfectly.
