Error code 228: camera unsupport cmd state

Error code 228: camera unsupport cmd state · 发表于2015-10-19

试FPVDemo的时候出现的错误码
屏幕上没有画面回传，始终黑屏。那几个button摁的时候出现以下信息：
Error code:228
Error msg: DJI Camera Unsupport Cmd State

还偶尔会出现:
Error code:0

请问可能是什么问题呢

目测是当前相机不在capture mode，跑去usb mode了。

https://dn-dev-dji-front.qbox.me ... Def.CameraMode.html

临时解决方案1：打开DJI GO，DJI GO会在一开始初始化一次相机状态。（在图传画面上记得切去相机功能而非录像功能，不然你拍照的时候仍然会提示228，因为record mode不支持capture相关指令。）

永久解决方案2：在运行你的APP时第一步先初始化照相机模式为capture mode。（其实我觉得教程里面应该提及这一点）

然后现在这个问题解决了  但是依旧黑屏  可是那几个按键都能用拍照片录像什么的  我去sd卡里查看了一下都有相应的照片和视频真是好奇怪我之前不知道用什么方法把demo project导入到AS(但不是gradle build) 运行后完全可行没有明显bug
可是自己在AS上按照教程做了一遍应该是没有改核心的东西怎么会有这个奇怪的问题呢原谅我是个JAVA+AS新手。。。

肉眼上看起来没什么问题……（如果你用的DjiSurfaceView_02在做显示）

如果是android的话，多重启几次看看……有时候android解码器自己会抽风

我终。。。。终于解决了。。。。之前怎么搜都搜不到解决方案搜了DJI SDK v2.4 以后马上就搜到了这帖子：http://forum.dev.dji.com/thread-31789-1-1.html原来v2.4更新后 djiGLSurfaceView.start();之前要加个DJIDrone.getDjiCamera().setDecodeType(DJICameraDecodeTypeDef.DecoderType.Software);

噢漏。。。。tutorial里似乎没有提及 demo project用的是eclipse老版本当时我还差点想换掉整个SDK...

为什么我的sdk里面没有DJIDrone.getDjiCamera().setDecodeType(DJICameraDecodeTypeDef.DecoderType.Software); setdecodetype方法都没有，sdk是2.4.1的
