使用pullrtsp2pushrtsp拉RTSP视频流转到其他RTSP服务器时出错，连接断开，转到lal的RTSP服务器正常

[viccom]

测试环境：服务器和测试客户端都是Linux（Ubuntu22.04）
服务器：在服务器上部署了多个RTSP服务器，其中服务器1部署lal，服务器2部署go2rtc，服务器3部署mediamtx。
测试客户端：pullrtsp2pushrtsp，ffmpeg

测试过程：

1. 使用pullrtsp2pushrtsp分别将本地网络的rtsp视频源拉流转推到rtsp服务器，命令如下：
   pullrtsp2pushrtsp -i rtsp://admin:[email protected]:554/h264/ch1/main/av_stream -o rtsp://xxxx.com:8554/camera1 -t 1 -y 1
   上面命令除了目的rtsp地址不一样，其他都一样，测试结果：
   1）lal服务器接收正常，在Windows端使用potplayer可正常看实时视频。
   2）go2rtc服务器无法接收，go2rtc服务器端报错：undefined error=wrong content type caller=github.com/AlexxIT/go2rtc/internal/rtsp/rtsp.go:225；pullrtsp2pushrtsp发送端报错：start tunnel failed. err=EOF([] header.go:50) - pullrtsp2pushrtsp.go:169
   3）mediamtx服务器无法接收，错误信息和2）差不多。

2. 使用ffmpeg 分别将本地网络的rtsp视频源拉流转推到rtsp服务器，命令如下：
   ffmpeg -fflags +genpts -rtsp_transport tcp -i rtsp://admin:[email protected]:554/h264/ch1/main/av_stream -vcodec copy -f rtsp rtsp://xxxx.com:8554/camera1
   测试结果：
   1）go2rtc服务器接收正常，在Windows端使用potplayer可正常看实时视频。
   2）mediamtx服务器接收正常，在Windows端使用potplayer可正常看实时视频。

3）lal服务器无法接收，服务器运行日志如下：
