请注意：即使添加了端口转发标志，此问题仍然存在，因此其他 SO 答案在这里对我没有帮助。我知道我在这里询问的是开源 MediaMTX RTSP 服务器，但我相信这本质上是一个纯粹的 Docker 问题；因此，任何具有 Docker 网络经验的人都可以回答这个问题，无论他们是否有 MediaMTX 的经验。
我使用的是 Mac 笔记本电脑。我通过 docker 运行 MediaMTX，如下所示：
docker run --rm -it -p 8554:8554 bluenviron/mediamtx:latest
2023/10/16 15:05:22 INF MediaMTX v1.2.0
2023/10/16 15:05:22 INF configuration loaded from /mediamtx.yml
2023/10/16 15:05:22 INF [RTSP] listener opened on :8554 (TCP), :8000 (UDP/RTP), :8001 (UDP/RTCP)
2023/10/16 15:05:22 INF [RTMP] listener opened on :1935
2023/10/16 15:05:22 INF [HLS] listener opened on :8888
2023/10/16 15:05:22 INF [WebRTC] listener opened on :8889 (HTTP)
2023/10/16 15:05:22 INF [SRT] listener opened on :8890 (UDP)
我可以确认它正在运行：
docker ps

因此看起来
ffmpeg有人能发现我可能出问题的地方吗？
使用以下内容：
docker run --rm -it --network=host -p 8554:8554ffmpeg -re -stream_loop -1 -i fireplace.mp4 -c copy -f rtsp -rtsp_transport tcp rtsp://localhost:8554/mystream通过以下方式查看流：
ffplay -rtsp_transport tcp rtsp://localhost:8554/mystream说明：
由于您在 Mac 上运行此程序，因此您可能正在使用 Docker Desktop。 Docker Desktop 文档 对于主机网络有这样的说法：
主机网络驱动程序仅适用于 Linux 主机，Docker Desktop for Mac、Docker Desktop for Windows 或 Docker EE for Windows Server 不支持。
由于您正在运行
docker run --rm -it --network=host -p 8554:8554 bluenviron/mediamtx:latest--network=host要解决此问题，您需要显式转发您想要使用的端口。我能够在 Mac 上运行以下内容：
docker run --rm -it -p 8554:8554 bluenviron/mediamtx:latest为了测试其是否有效，我使用以下命令通过 RTSP 服务器传输一系列连续的灰色帧：
ffmpeg -readrate 1 -f lavfi -i color=c=gray -vf "fps=25,format=yuv420p" -c:v libx264 -f rtsp -rtsp_transport tcp rtsp://localhost:8554/mystream-readrate 1-f lavfi -i color=c=gray-vf "fps=25,format=yuv420p"-c:v libx264-f rtsp -rtsp_transport tcp-rtsp_transport tcp我能够通过使用以下命令通过 ffmpeg 查看该流来确认该流是否正常工作：
ffplay -rtsp_transport tcp rtsp://localhost:8554/mystream
