如果你安装bad 和 ugly 还不行

解决方案：重装gstreamer

wink wik

但安装方式和常规的不一样

安装gstreamer

sudo apt update

官网：Installing on Linux

sudo apt-get install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libgstreamer-plugins-bad1.0-dev gstreamer1.0-plugins-base gstreamer1.0-plugins-good gstreamer1.0-plugins-bad gstreamer1.0-plugins-ugly gstreamer1.0-libav gstreamer1.0-tools gstreamer1.0-x gstreamer1.0-alsa gstreamer1.0-gl gstreamer1.0-gtk3 gstreamer1.0-qt5 gstreamer1.0-pulseaudio

安装基础包之外的rtsp服务器

sudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libgstrtspserver-1.0-dev libgirepository1.0-dev
pkg-config --modversion gstreamer-rtsp-server-1.0

python的gstreamer包（接口）

pip install --index-url https://pypi.org/simple pygobject
# 如果你默认是镜像源，加个官网地址哦，要不然下载不了

如果报错，缺啥补啥

我是pycairo

sudo apt install libcairo2-dev pkg-config
pip install --index-url https://pypi.org/simple pycairo

测试

在pycharm里看到

from gi.repository import Gst 报错，不要怕，大胆运行

# test_gstreamer.py
from gi.repository import Gst

Gst.init(None)
print("GStreamer initialized successfully!")

# test_rtsp_server.py
from gi.repository import Gst, GstRtspServer

Gst.init(None)
print("GStreamer RTSP Server module is available!")

发出rtsp

import sys
import gi

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

loop = GLib.MainLoop()
Gst.init(None)

class TestRtspMediaFactory(GstRtspServer.RTSPMediaFactory):
    def __init__(self):
        GstRtspServer.RTSPMediaFactory.__init__(self)

    def do_create_element(self, url):
        # Set mp4 file path to filesrc's location property
        src_demux = "filesrc location=/home/oem/workspace/rtsp/test_videos/SampleVideo_1920_1080_10min.mp4 ! qtdemux name=demux"
        h264_transcode = "demux.video_0"
        # Uncomment following line if video transcoding is necessary
        # h264_transcode = "demux.video_0 ! decodebin ! queue ! x264enc"
        pipeline = "{0} {1} ! queue ! rtph264pay name=pay0 config-interval=1 pt=96".format(src_demux, h264_transcode)
        print("Element created: " + pipeline)
        return Gst.parse_launch(pipeline)

class GstreamerRtspServer():
    def __init__(self):
        self.rtspServer = GstRtspServer.RTSPServer()
        self.rtspServer.set_service("8080")  # 设置端口
        factory = TestRtspMediaFactory()
        factory.set_shared(True)
        mountPoints = self.rtspServer.get_mount_points()
        mountPoints.add_factory("/stream1", factory)  # # 另一个终端：vlc -v rtsp://127.0.0.1:8080/stream1 拉流
        self.rtspServer.attach(None)

if __name__ == '__main__':
    s = GstreamerRtspServer()
    print("Starting RTSP server on rtsp://127.0.0.1:8080/stream1...")
    loop.run()
    print("RTSP server stopped.")

拉流

# bash
vlc -v rtsp://127.0.0.1:8080/stream1
