Gstreamer RTSP服务器不工作（SDP不包含流）

Question

下面是我的GstRtspServer代码，现在应该只传输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，获取“Stream ready”，然后输入命令行：

^{pr2}$

收到这个：

Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...

C:\gstreamer\1.0\x86_64\bin>

我还收到Python中的“Client connected”，视频的第一帧打开，过一会儿就关闭了。在

• 在Gst.parse_启动（'playbin uri=file:///E://…示例_视频.mp4'工作正常-（带完整地址）
• VLC说不可能打开rtsp://192.168.1.15：8554/视频
• 我试过在本地网络的另一台计算机上启动它
• 以及127.0.0.1
• 无延迟接收流=0！解码箱！自动视频接收器

怎么了？我期待着你的帮助！在

您的服务器正在监听：

self.port = '554'

当您尝试播放端口8554时：

VLC says that it is impossible to open rtsp://192.168.1.15:8554/video
