如果上传视频使用保利威视的话要注意一下几点:
1.如果上传是正常的,但是到保利威视后台却有绿屏的情况下,查看自己拍摄的视频分辨率,一般出现都是分辨率太低
2.播放的视频不清楚,需要自己在保利威视后台设置播放的格式,一般分流畅-->标清-->高清等
3.如果上传之后,但是获取不到返回的mp4地址,就去自己的管理后台看一下,自己的视频到底有没有上传上去
4.有时候根据视频url会出现点击播放但是没有视频url却存在的问题,因为保利威视会有个视频转码的过程,此处需要自己处理一下,可根据网络url,截取视频第一帧,通过第一帧的image,判断image是否等于nil,如果等于nil,就做其他处理,例如提示视频正在转码类,不等于nil就直接播放
