ffmedia拉流报错

sky-brid

使用ffmedia获取大华ICC开发平台生成的rtsp流一直报错，但是这个视频流用vlc或者ffmpeg查看都是可以的，请问有什么出来办法吗。

将./demo rtsp://192.168.1.118:9090/dss/mo ... 241&substream=1
更改成
./demo rtsp://192.168.1.118:9090/dss/monitor/param?cameraid=1000002%241\&substream=1

因为&字符是shell的关键字添加个\在&前面转义就可以了

从日志中看，ffmedia获取到的rtsp地址是对的了，但是仍然无法获取到视频流
