What configuration are you using? What is the output of player.getConfiguration()?
Base config on Shaka demo app
What did you do?
Load the manifest in Shaka demo app
What did you expect to happen?
Shaka should show 3 choice in the caption menu.
What actually happened?
The manifest contains 3 different subtitles but Shaka show only 2 possible choice: "en", "ger".
Shaka ignore the second "ger" subtitle even if the representation id and bandwidth are different.
