XIU version
For example: v0.13.0

Describe the bug
Crash when RTSP stream returning audio without encoding_name???

使用时发现 xiu 抛出错误，设备是 unv 的网络摄像头：

xiu -c xiu.toml

于是找到相关代码：

402             match media_name.as_str() {
403                 "audio" => {
404                     let codec_id = rtsp_codec::RTSP_CODEC_NAME_2_ID
405                         .get(&media.rtpmap.encoding_name.to_lowercase().as_str())
406                         .unwrap()
407                         .clone();

我也不知道为啥这个流没有名字。VLC、ffmpeg 正常。 ffplay 的信息为：

应该是上游的问题，不过这个问题真的很无语……
