Plex introduced an Auto-Sync Subtitles feature that aligns subtitles with audio using an algorithm that detects voices, supporting external SRT files and those from OpenSubtitles.com.
The feature requires a Plex Pass subscription, voice activity detection, and media analysis enabled on the server, but won't work on some systems like FreeBSD, Nvidia Shield, and certain NAS servers.
Plex is expanding its app offerings, including a new dedicated photos app in open beta, and currently offers a 20% discount on Lifetime Plex Pass subscriptions.
What I'd like is the ability to fix out-of-sync audio. My wife won't watch movies/tv/etc on Plex (on Roku) because some part of it creates an audio delay, and it really bothers her that the audio doesn't match the lip movement.
I've tried all sorts of settings, both server and client. It mostly only seems to affect my Roku, though, so that seems to be the issue. I just want to add a small video delay or something.
Do you have somewhere I could get more information?
Most of my video files are mkv, encoded as MPEG, and audio is AC3 5.1, but I'm only playing audio through my TV speakers, so maybe it's transcoding for my cheap 2-speaker setup? I also typically enable subtitles, which I think can cause transcoding.
I've enabled Direct Stream wherever I could find it, but it didn't seem to have any effect.
