나는 안드로이드 튜토리얼 here의 방법을 사용하여 내 모토로라 드로이드 한 비디오를 스트리밍하고있어에서로 비디오를 야기한다. 내가 연주하고 싶은 두 가지 형식과는 다른 동작이 나타납니다. 첫 번째 유형 (youtube lq 3gp)은 정상적으로 재생됩니다. TIOverlay 기능 (그래서 비디오)를 실행하지 않습니다 전에 비디오가 오디오와 동기화의 인출되면 두 번째 유형 (유튜브 본부의 MP4는) 다음, 오디오를 재생하기 시작합니다. 나는 잘 작동하는 모바일 YouTube 사이트에서 재생되는 형식이기 때문에 hq mp4 형식이 내 휴대폰에서 지원된다는 것을 알고 있습니다. 형식에 대한 자세한 내용은 here입니다.안드로이드 MediaPlayer를 지연 표면 무승부 동기화
그래서 내가 하나가 실행하는 TIOverlay을 강제 할 수있는 방법, 또는 그것을 준비하고, 그 시점까지 비디오를 시작하지 수신하는 방법이 필요합니다 같아요. 아래의 일부 logcat 출력은 흐름을 보여줍니다. 두 경우 모두 onPrepared()가 호출 될 때 흥미 롭습니다. 3gp는 onPrepared() 전후에 TIOverlay 호출을하는 것처럼 보이지만 mp4는 이후에만 수행합니다.
편집 : 동일한 코드가 Motorola Droid 3에서 작동하는 것으로 보입니다. 그 비디오 형식이 내 Droid 1의 YouTube에서 작동하는 경우에도 내 앱에서도 작동해야합니다. 나는 조금 버퍼링 될 때까지 동영상을 재생 기다리고했습니다. 이 방법으로 문제를 해결할 수있을뿐만 아니라 비디오를 시작할 때 버퍼가 다시 시작되었습니다.
