ffmpeg - 检索rtsp时如何将连接超时添加到ffmpeg命令？

Question

我使用以下命令将 rtsp 流传输到 .mp4 文件:

ffmpeg -rtsp_transport tcp -timeout 5000000 -i "rtsp://zigong.stream.xl02.cn:557/HongTranSvr?DevId=1b038d27-858c-46a1-b803-a2984af343df&Session=1b038d27-858c-46a1-b803-a2984af343df"  -vcodec copy -t 5 -y "capture.mp4" 

结果如下:

[rtsp @ 0x5655577ccc00] Unable to open RTSP for listening
rtsp://zigong.stream.xl02.cn:557/HongTranSvr?DevId=1b038d27-858c-46a1-b803-a2984af343df&Session=1b038d27-858c-46a1-b803-a2984af343df: Cannot assign requested address

但如果我删除超时选项，它的措辞很好......

尝试更新FFmpeg版本并替换-timeout进入 -stimeout .
这个问题在几个月前得到了修复。 [ ref ]
