关于python：Gstreamer RTSP Server not working(SDP 不包含流)


Gstreamer RTSP Server not working (SDP contains no streams)

这是我的 GstRtspServer 代码，现在应该只流式传输 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，得到 \\'Stream ready\\' 然后在命令行中输入：

1
C:\\gstreamer\\1.0\\x86_64\\bin>gst-launch-1.0 rtspsrc location=rtsp://192.168.1.15:8554/video latency=0 ! decodebin ! autovideosink

并收到这个：

此外，我在 Python 中收到了 \\'Client connected\\'，视频的第一帧打开，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
  • 我已经尝试在本地网络中的另一台计算机上启动它
  • 也有 127.0.0.1
  • 并无延迟地接收流=0！解码器！自动视频接收器

有什么问题？我期待着您的帮助！

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
