Roku Developer Program

Hello,
I want to allow the user watch the content from a roku channels with subtitles (2-3 languages for some of the videos). I'm thinking about 2 solutions to allow the users to enable/disable subtitles, and to select a specific language:
1. A "roMessageDialog" screen displayed when the user clicks on "Play with subtitle", and in this roMessageDialog the user will be able to select the language of subtitle
2. A "roParagraphScreen" screen displayed in the app, and in this screen the user will be able to enable/disable subtitles for all the videos and also to select a language

Any other ideas?

Thanks,
Ionatan

What format are the subtitles provided in. We would suggest you do nothing and let the 5.3-introduced caption preferences handle it all for you. If you're providing the subtitles in 608 or ttml, we should be able to automatically handle it if you're using roVideoScreen and pressing * during playback should let the viewer control the presence of captions and which track to use.

We provide .srt files for the videos. Is there a way to convert them to 608 or ttml? Or is there any "caption preferences" feature scheduled for the next firmware updates?

Does caption preferences work with external ttml files?

Thanks
