gloverlaycompositor: Subtitle overlay not showing on Android
Android GStreamer version 1.16.1 did fix the crash (https://gitlab.freedesktop.org/gstreamer/gst-plugins-base/issues/501) but it still cannot process the subtitles on most MKV videos.
As a matter of fact, please try opening/streaming this mkv file and select any available subtitle (it won't work using gstreamer v1.16.0 or v1.16.1):
However, this mkv file is showing his subtitles (it should work using gstreamer v1.16.0 or v1.16.1):
I do not have any issues showing subtitles using Android VLC with both mkv files.
