gloverlaycompositor: Crash on Android when overlaying subtitles
Hi,
I have been working on the android gstplayer example. However, I keep getting crashes when the video should display subtitles and when I set the following commands:
gst_player_set_subtitle_track_enabled(player->player,TRUE);
gst_player_set_subtitle_track(player->player,0);I don't get any crashes when I set:
gst_player_set_subtitle_track_enabled(player->player,FALSE);Please, could you tell me what I am doing wrong with this feature? Note that I successfully make gst_player_set_audio_track work with your app example.
You can easily reproduce this issue if you pull following repo and using the lastest gstreamer android lib 1.14.4 Github repo: https://github.com/GStreamer/gst-examples/tree/master/playback/player/android
Thanks to @slomo, I could get a way to debug this issue using the addr2line command on /lib/arm/libgstreamer_android.so addr2line -a 00f3eb7c -e /lib/arm/libgstreamer_android.so
