Reproduce the play-video-then-finish-activity sequence on the reported Nokia Android 8.0 device and inspect the native crash path in libijkplayer.so. Start with the backtrace entries ffp_wait_stop_l and ijkmp_shutdown_l, using the tombstone details to investigate shutdown. Done means the activity can finish without the reported SIGSEGV.
