Android 在某些设备中使用媒体播放器录制视频时启动失败-19

我正在尝试使用带有摄像机配置文件480P的媒体录像机录制480X640视频，但在某些设备中，当我按下开始录制时，它给我的启动失败-19

相机不支持480P，那么我应该怎么做才能录制480 X 640

---

如果摄像机不支持480p的视频录制，则不能使用480p进行录制。以其他支持的分辨率记录<代码>低质量和

高质量

是唯一保证受支持的。如果您不喜欢

QUALITY\u LOW

结果，并且

QUALITY\u 480P

不可用，请在

QUALITY\u HIGH

记录您的代码，查看是否支持480P，请使用

hasProfile（）

？我没有检查hasProfile（），即使我检查hasProfile并假设相机不支持480P，那么我应该如何录制480 X 640。我尝试使用低质量，它也可以工作，但它给我的171X144视频质量非常差。请检查我的编辑。我使用getsupportedvideosizes（）获取支持的视频大小，并在此基础上设置视频的视频大小。它在我的手机上工作，但我仍然不确定它是否在每一部手机上都能工作。@ShashankAgarwal:我怀疑这个星球上是否有人知道什么代码在每一部手机上都能工作。：-）当然，我不能说它会不会。我没有尝试混合使用

setProfile（）

和

setVideoSize（）

，所以我不知道会发生什么，对不起。它现在使用的是相同的代码：），我不知道你为什么不使用我的应用程序回复我的twitter视频。我只是你的另一个粉丝。无论如何，再次感谢！
