Gstreamer RTSP 服务器不工作（SDP 不包含流）

Question

这是我的 GstRtspServer 代码，现在应该只是流式传输 mp4 文件：

import gi
gi.require_version('Gst', '1.0')
gi.require_version('GstRtspServer', '1.0')
from gi.repository import Gst, GObject, GstRtspServer

GObject.threads_init()
Gst.init(None)


class RTSP_Server:
    def __init__(self):
        self.server = GstRtspServer.RTSPServer.new()
        self.address = '192.168.1.15'
        self.port = '8554'
        self.launch_description = '( playbin uri=file:///E://...sample_video.mp4 )'

        self.server.set_address(self.address)
        self.server.set_service(self.port)
        self.server.connect("client-connected",self.client_connected) 
        self.factory = GstRtspServer.RTSPMediaFactory.new()
        self.factory.set_launch(self.launch_description)
        self.factory.set_shared(True)
        self.factory.set_transport_mode(GstRtspServer.RTSPTransportMode.PLAY)
        self.mount_points = self.server.get_mount_points()
        self.mount_points.add_factory('/video', self.factory)

        self.server.attach(None)  
        print('Stream ready')
        GObject.MainLoop().run()

    def client_connected(self, arg1, arg2):
        print('Client connected')


server = RTSP_Server()

我运行它，让“Stream ready”，然后输入命令行：

C:\gstreamer\1.0\x86_64\bin>gst-launch-1.0 rtspsrc location=rtsp://192.168.1.15:8554/video latency=0 ! decodebin ! autovideosink

然后收到这个：

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Progress: (open) Opening Stream
Progress: (connect) Connecting to rtsp://192.168.1.15:8554/video

C:\gstreamer\1.0\x86_64\bin>

我还在 Python 中收到“客户端已连接”，视频的第一帧打开，然后在片刻后关闭。

• Gst.parse_launch('playbin uri=file:///E:/​​/...sample_video.mp4') 工作正常 - （带有完整地址）
• VLC说无法打开rtsp://192.168.1.15:8554/video
• 我已尝试在本地网络中的另一台计算机上启动它
• 127.0.0.1 也是如此
• 并且接收没有延迟的流=0！解码器！自动视频接收器

有什么问题？我期待您的帮助！

Answer 1

您的服务器正在监听：

self.port = '554'

当你尝试使用 8554 端口时：
