如何使用intents录制.mp4格式的视频

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

File videoFile = new File(Environment.getExternalStorageDirectory(), "myvideo.mp4");
Uri videoUri = Uri.fromFile(videoFile);

Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, videoUri);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);

int REQUEST_VIDEO_CAPTURE = 1;
startActivityForResult(intent, REQUEST_VIDEO_CAPTURE);

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == REQUEST_VIDEO_CAPTURE && resultCode == RESULT_OK) {
        // 视频录制成功
        // 可以在这里处理录制成功后的操作，如播放视频、上传视频等
    }
}
