Subtitles cause video stuttering/lag

[burnout123]

Hi,

I believe this is an issue also present in the VLC for iOS (https://forum.videolan.org/viewtopic.php?f=36&t=146513)

Every time I play subtitles on my Sony Android TV (Android 9.0), VLC version 3.1.6. the video stutters/lags the second the subtitle is displayed. It doesn't matter what video file I play. I always use .srt subtitles.

The issue is not present if I disable the subtitles.

Please let me know if there is a solution available, maybe a beta version of VLC or some setting I could use.
Thank you.

Hi, there is a fix pending for 4.0 release with hardware accelerated outputs, but it's difficult to port to 3.0.x release. Maybe this would be possible to integrate as additional patches but not sure. I'll keep you updated.

Thank you for your prompt reply @unidan.

Hey, is there any fix for this yet? Maybe some beta version that has the fix? Thanks for the update.

Hi, I have to clean up the patches and add support for the subtitles format I don't handle yet, but it's working and we have another set of patches allowing to render things way more time in advance. I'll check if the android team can use it as patches for 3.x release.

Hey @Unidan, any updates? Thanks.

I'm encountering the same issue on Android TV and was wondering if there is an update. I joined the beta branch hoping it would be fixed in that version, but had a whole different problem that prevents me from picking a subtitle file from a directory so I can't test if the stuttering happens in the beta as well. Either way I would prefer to use the stable version.

Hey, sorry to be such a nag, but are there any news regarding the issue? It makes my VLC/Android TV experience horrible. I'd be happy to get any advice or solution.

Hi, I haven't merged the patches yet and I'm not sure it's possible to merge them for 3.0. However, 4.0 currently has a dedicated component to avoid glitching the subtitles preparation time on the video rendering.
