的序列创建视频对于机器人创建从图像序列的视频我用javacv 0.6库，但我满足问题： 它通常工作在HTC感觉（4.0.1的Android，处理器类型的ARMv7）和HTC渴望（安卓2.3.3，处理器类型ARM7）手机，但它不会对HTC野火工作 （安卓2.3.5，处理器类型ARMv6的）电话特别是在代码从图像javacv
FFmpegFrameRecorder recorder = new FFmpegFrameRecorder(videoFilePath,
TalkingPhotoConstants.VIDEO_FRAME_WIDTH,TalkingPhotoConstants.VIDEO_FRAME_HEIGHT);
这部分失败附上代码。

没有例外。
1.how可以解决呢？
2.I存在这样的问题与设备的处理器类型连接的版本。
如果我是正确的我该如何解决呢？
在此先感谢。
