Как записывать потоковое видео?

Я могу воспроизводить потоковое видеос подключением к http-серверу в SurfaceView. И я создавал ContextMenuдля записи видео, добавляя пункты меню StartRecordingи StopRecording. Но я могу записать видео с камеры, вызвав mediaRecorder.setVideoSource(MediaRecorder.VideoSource.CAMERA);

Здесь я хочу установить источник видео в качестве источника потокового видео. Есть ли возможность это сделать?

Но я хочу записывать потоковое видео во время его воспроизведения. Подскажите, пожалуйста, как сделать запись во время воспроизведения?

Не могли бы вы предоставить пример кода для этой проблемы?

Мой пример кода показан ниже:
