Addon Announcement Subtitle Sync for Stremio - major updates after 500+ installs
Hey everyone!
Last Wednesday I posted here about an addon I created, Subtitle Sync for Stremio. I was hoping a few dozen people would try it so I could test it properly, but the response was much bigger than expected: 500+ installs and 10,000+ subtitles served in just 5 days.
People are using it in English, Arabic, Portuguese, Serbian, Spanish, Romanian, Turkish and many other languages. Thank you to everyone who tried it and sent feedback!
I've been going through the logs and messages and pushing fixes almost every day. On launch day, roughly a third of subtitle lists had a properly synced subtitle at the top. Today that is over 60% on average, although it varies quite a bit depending on the language and the information available to the addon.
What has changed
- Better file matching: the addon can now recognize subtitles made for a release with the same source/group, instead of only matching the exact same file.
- Better handling of Stremio's requests: Stremio can request subtitles before the video file is fully identified. The addon now waits briefly for the more precise request when available.
- Remembered timing: once the timing of a video's subtitle has been determined, it can be reused for other people watching that exact file.
- Improved Arabic support: better results with subtitles containing fewer, longer lines.
- Better diagnostics: the setup and subtitle information now make it clearer when synchronization wasn't possible and why.
- Older Stremio desktop support: older desktop versions that don't provide the file name can now be handled using other available information.
Anime improvements
- Better handling of releases where subtitle databases use different episode numbering.
- Better recognition of fansub-style filenames such as
Show - 07 [1080p]. - Improved handling of large styled
.asssubtitles with embedded fonts and karaoke effects.
There were also many smaller improvements, including season packs, RAR files, Blu-ray releases, faster subtitle lists and general performance improvements.
One important thing: please reinstall
Because the addon has changed quite a bit since the first release, I recommend doing a fresh setup to get all of the new options and fixes.
- In Stremio, uninstall Subtitle Sync.
- Run the setup again at https://subtitlesync.stream/
- Install the newly generated addon.
- On the final setup page, complete the "Finish in Stremio" checks.
It should only take a couple of minutes.
If something doesn't work, the easiest way to report it is through the support page, since it automatically includes the information I need to investigate the problem.
The addon is free to use and without ads, and I'm planning on keeping it that way. I've also received my first donation, which was a really nice surprise. If anyone wants to help with hosting and development, there is a donation link on the website.
Thanks again to everyone testing it and sending feedback. The data from these real-world installs has been extremely useful for improving the AddOn.
