The
SubtitleViewis not an option cause off screen rendering is required in this case.
Reading slightly between the lines here, are you trying to render subtitles as part of a batch transformation of the video?
I think the Media3 Transformer library would be the right tool for that (maybe you're already using it) - but I don't think it currently has support for rendering Cue objects.
If I've understood the request correctly we can use this issue to track it as a potential enhancement.

Thanks for reply
Yes. I need to draw the video and selected subtitles into separate SurfaceTextures, and then process them further in subsequent steps. After that, blend them and complete the screen rendering. I found SubtitlePainter and part of CanvasSubtitleOutput are very helpful. However they are private apis. Perhaps the best way for now is to just copy them into my project and make the necessary changes.
