标题: 视频流已经成功推后台黑屏
帽子上的视频流已经推到手机了，但是我把手机的推到后台就是黑的，应该是格式不对，是要用 NV12ToNV21这个方法不？怎么用

现在我推到后台的视频颜色不对？NV12ToNV21这个方法怎么用

CameraUtils.findColorFormat() == 0怎么转else又怎么转

byte[] nv21 = new byte[data.length];
NV12ToNV21(nv21,data,width,height);

请问下，就是我手机连头盔时头盔时关闭的，然后点了连接后再把头盔打开会有重连机制吗？

没有，这个上层可以做判断来实现重连

case IRTSPCam.RTSP_EVENT_OPEN:
IRTSPCam.RTSP_RESULT_FAILED是等这个事件出发后实现重连吗

是调下面那个方法就可以了吗？

author: besovideo time: 2019-12-19 13:50
嗯，您动手试试。

author: alexanderjia time: 2019-12-19 13:55
爷，那个第二方法里的regexAIp，regexBIp，regexCIp这几个参数是什么？然后第一个方法最后获取的是个List，我用第几个？

author: besovideo time: 2019-12-19 14:48
电话沟通解决了吧？

author: alexanderjia time: 2019-12-19 15:12
解决了，现在的问题是帽子连不上热点。好蛋疼！
