MediaPlayer в версии 7.1.1 ниже не может воспроизводить RTSP только с сообщением об ошибке E / MediaPlayer: Ошибка (1, -2147483648)

Question

Я создал приложение для потоковой передачи видео в реальном времени с камер безопасности. Применяя тесты с различными типами устройств и android релизной версией, я обнаружил, что она работала так же хорошо только на релизной версии более 7.0, на более низких версиях только сообщение об ошибке " E / MediaPlayer: Ошибка (1, - 2147483648)"можно найти в журнале.

Вот код ...

Я искал, что изменилось с версии выпуска 7.0 до 7.1. 1 на странице do c, но я ничего не нашел!
