unity 调用大华设备视频

这段时间一直在搞大华的执法记录仪设备的视频播放，总所周知，unity平台对视频播放不是很友好，而大华的SDK只有c#版本的并没有专门为unity做出来SDK，最开始尝试过使用SDK里面的方式获取YUV格式的视频流，再讲YUV格式的视频流转换为unity可以播放的格式，但是这个格式转换经常出现问题，而且很卡顿，所以呢我就用了ump插件进行rtsp视频流播放，还算是比较流畅的。

ump插件下载链接：https://pan.baidu.com/s/1AW50i41MgGHR9npdgJOf6Q 提取码：ahez （仅供学习，请勿商用）

大华的设备rtsp流构成分析：

rtsp://[username]:[password]@[address]:[port]/cam/realmonitor?channel=[id]&subtype=[type]

rtsp:// => 协议格式头
username => 用户名，例如：admin
password => 密码，例如：123456
address => IPC设备的网络地址，例如：192.168.1.65
port => IPC设备的RTSP输出端口，默认为554，若为默认可不填写
id => 通道号，起始为1。例如通道2，则为channel=2。
type => 码流类型，主码流为0（即subtype=0），辅码流为1（即subtype=1）。

原文链接：https://blog.csdn.net/haoyitech/article/details/79563281 (原文介绍了大华和海康的rtsp视频流构成，我这里只用了大华的，如果有需要海康的，请自行查找)

插件非常好用，只需要将UniversalMediaPlayer预制体拖放至场景中，将脚本上的rtsp流修改之后就可以查看视频了。

但是！由于我们需要的功能执法记录仪上没有，我们就定制了我们需要的功能，然后将执法记录仪设备系统升级了，结果升级之后，之前的获取rtsp视频流的功能，居然无法使用了，我在和大华的技术部联系过之后，得到的结论是升值后确实不能使用rtsp来播放视频流了，如果有需要可以定制。emm... ... 这就很尴尬了，定制是不可能的，但是问题还是要解决的，在热心同时的提示和帮助之下，我们采取了使用开启一个winform程序专门用来播放视频，虽然界面丑了点，但是还是完成了需要的功能。
