BufferQueue foi abandonado: Ao reproduzir vídeo com TextureView

Toda vez que pausa minha atividade (na verdade, Fragment) para acessar outro aplicativo, ao retornar com onResume, tento retomar a reprodução do vídeo, mas ele não é reproduzido: uma tela em branco é exibida. Após a investigação, vejo o seguinte no Logcat

E/BufferQueueProducer: [unnamed-23827-0] queueBuffer: BufferQueue has been abandoned
E/MediaPlayer: error (1, -38)
E/MediaPlayer: error (1, -38)
E/MediaPlayer: error (1, -38)
E/MediaPlayer: error (1, -38)
E/BufferQueueProducer: [unnamed-23827-0] connect(P): BufferQueue has been abandoned

Aqui está o código que eu chamo no currículo

player.seekTo(mVideoSeekPosition);
player.start();

FYI: Estou tentando aplicar esta resposta ao meu caso, mas não posso:O que posso fazer quando o BufferQueue for abandonado?

ATUALIZAR

Eu lutei para fazer tudo sozinho, mas ainda estou caindo. Então, eu estou postando o código inteiro para obter ajuda
