我有一個mp4文件，我已經轉換使用H.264基線編碼手剎。這在瀏覽器中正常播放。不能在薑餅設備流視頻
我已經創建了一個應用程序，可以在VideoView中傳輸此視頻。我已經在4.0.1和4.3中測試過了，它工作正常。視頻播放完美無瑕。
使用2.3.3 android模擬器，我可以聽到聲音，但沒有視頻。當我在實際的2.3.3設備（HTC Evo）中試用它時，根本無法播放視頻。我收到「此視頻無法播放」錯誤。我不太確定薑餅是否支持這個功能，但看起來好像是這樣，因爲模擬器至少可以播放音頻。
我在logcat中看到了一些HDMI許可信息，但我不確定它的含義。我會很感激任何反饋。謝謝！
這裏的logcat的：

添加您用來播放視頻的代碼可能很有用。 – anthonycr
原來是互聯網連接問題。手機連接到wifi，但沒有得到任何互聯網。 logcat誤導我認爲這是一些不兼容問題。 –
