The origin may be negative if the subtitle starts off-screen but extends into the screen for example. TTML1 defines `tts:origin` in terms of [`length`](https://www.w3.org/TR/2018/REC-ttml1-20181108/#style-value-length), which allows a prefix of `+`, `-` or nothing, and it's the [same in TTML2](https://www.w3.org/TR/2018/REC-ttml2-20181108/#style-value-length).

ExoPlayer module
This module provides ExoPlayer, the Player implementation for local media
playback on Android.
Getting the module
The easiest way to get the module is to add it as a gradle dependency:
implementation 'androidx.media3:media3-exoplayer:1.X.X'
where 1.X.X is the version, which must match the version of the other media
modules being used.
Alternatively, you can clone this GitHub project and depend on the module locally. Instructions for doing this can be found in the top level README.
