Remux is a simple remux/recode app based on FFmpeg. Features:
- Change container without reencoding
- Select, rearrange and duplicate tracks.
- Convert DTS to AC3/AAC for e.g.
It is NOT a muxer for joining elementary streams.
Disabled subtitle tracks by default since FFmpeg does not copy them in most cases
Love this app! But since I updated to Big Sur 11.3 it doesn't work quite right. I get some audio popping and the video and audio go out of sync after a few minutes. Stopping the Apple TV app and restarting fixes it for a few minutes, but then it goes back.
