More version details
Subtitle parsing for a given DASH asset (DRM protected) works fine in 1.4.0-alpha01 but in 1.4.0-alpha02 and 1.4.0-beta01 the playback fails with the following exception. Without provding the asset, can you help figure this out? Any info from the DASH manifest that I could provide to help? Again, same asset plays fine and displays subtitles in 1.4.0-alpha01
