Subtitles support for USharpVideo

This prefab adds support for SRT subtitles to USharpVideo - it will also work with base video players supported by VRChat (Unity and AVPro). To check this out in-game visit this test world or world from this list.

The core of this prefab is based on this code by Haï~.
Currently, there are minor issues for the Quest users - see here.

Features

• Subtitle synchronization with everyone in the instance
• Option to use own subtitles locally
• Rich customization with the ability for the players to save their settings

Worlds using this prefab

• Cinema Basill UDON
• Luminescent Ledge

Contact me if you want your world to be added to this list.

Requirements

• Unity 2019.4.29f1+
• UdonSharp v1.0.0+
• USharpVideo v1.0.0+

Installation

I suggest adding "subtitles" to your world's tags when using this prefab so that people can find worlds with subtitle support more easily.

1. Install UdonSharp first
2. Import USharpVideo (required even if you're not planning on using it)
3. Import latest release unitypackage
4. Drag the Subtitles prefab into your scene
   • when using USharpVideo you can also drag Subtitles prefab into USharpVideo in your scene and reset transform values
5. When a window asking you to import TextMeshPro Essentials appears - just do it
6. Add a reference in the Subtitles object (SubtitleManager script) to:
   • when using USharpVideo (Target Video Player field) - USharpVideoPlayer from the USharpVideo object
   • in any other case (Base Video Player field) - VRCUnityVideoPlayer or VRCAVProVideoPlayer that have to be somewhere in your scene - depends on which one you're using (you can change this dynamically)
7. Add a reference in the Subtitles/Overlay object (Video Screen field) to the video player's screen object, the overlay will copy the position and rotation of the screen on start
   • if this doesn't work on your world then you will have to manually adjust Subtitles/Overlay object's position and rotation to match the video screen object (while keeping the mentioned earlier field empty)
