Description
Use case description
Better SSA/ASS subtitle formatting support. This is an area where ExoPlayer/Media3 has lagged behind VLC.
There was this issue tracker for SSA format support: google/ExoPlayer#8435 (comment)
VLC achieves SSA rendering via https://github.com/libass/libass however because it was written in C, there was reluctance to use it.
A pull request has been sitting in the ExoPlayer report without being merged: google/ExoPlayer#10169
Proposed solution
Merge google/ExoPlayer#10169 and further improve SSA styling support using libass as reference and complete the support matrix here: google/ExoPlayer#8435 (comment)
Alternatives considered
Use libass like VLC
