>>65663>If you're so concerned about device compatibility why don't you use AAC?I don't like free AAC encoders and Opus is supported by anything less than 15 years old. It's also better at the bitrates I'm using than AAC. Also *nix support for the codec is better. If you have mpv (and every set-top device does) you can decode Opus for free.
I would have normally used an AC3 audio track and not touched the audio at all. However, AppleTV users can't decode it for free with the player they use for Plex/Jellyfin (Infuse wants money if you attempt it). This BD also had uncompressed audio and no AC3 audio track for several episodes that included 2 commentary tracks. Opus was the best compromise and was supported by every device used in testing (AppleTV, Roku, various Xbox consoles running Kodi, all android devices and Windows/*nix PCs running mpv and the old CCCP).
Basically, anything that supports AAC supports Opus unless it's 20+ years old.
