的序列創建視頻對於機器人創建從圖像序列的視頻我用javacv 0.6庫，但我滿足問題： 它通常工作在HTC感覺（4.0.1的Android，處理器類型的ARMv7）和HTC渴望（安卓2.3.3，處理器類型ARM7）手機，但它不會對HTC野火工作 （安卓2.3.5，處理器類型ARMv6的）電話特別是在代碼從圖像javacv
FFmpegFrameRecorder recorder = new FFmpegFrameRecorder(videoFilePath,
TalkingPhotoConstants.VIDEO_FRAME_WIDTH,TalkingPhotoConstants.VIDEO_FRAME_HEIGHT);
這部分失敗附上代碼。

沒有例外。
1.how可以解決呢？
2.I存在這樣的問題與設備的處理器類型連接的版本。
如果我是正確的我該如何解決呢？
在此先感謝。
