      代码说明:

    # 设置VLC库路径,需在import vlc之前
    os.environ['PYTHON_VLC_MODULE_PATH'] = "./VLC"

    这段代码是引入VLC,在项目当前目录下放入VLC

     VLC下载地址:https://www.videolan.org/

    可删除部分不必要文件减少项目体积

    import vlc

    安装python-vlc

    #这个要先安装python-vlc
    pip install python-vlc

    Player是封装的播放器类直接引用

    import tkinter as tk
    ......

    这段代码是给使用tkinter开发

    最后是

    PyQt5

    安装教程可参考:https://www.cnblogs.com/wohuiyijiu/p/12454130.html

    重要的三行代码(其余都是绘制控件,不做说明):

    self.player = Player("--network-caching=0")#"--audio-visual=visual","--effect-list=scope", "--effect-fft-window=flattop"
    self.player.set_window(self.frame.winId())
    # self.player.play("rtmp://192.168.1.3:1935/rtmp/test")
    # self.player.play("rtmp://192.168.1.5:1935/live/test3")
    # self.player.play("rtsp://admin:castle12345@192.168.1.120:554/LiveMedia/ch1/Media1")
    self.player.play("rtsp://admin:hik12345@192.168.1.64:554/h264/ch01/sub/av_stream")

    初始化播放器->设置句柄(设置在哪个frame播放,这里也不一定是frame,只要控件支持获取句柄应该都能播放)->传入播放地址播放

    代码没有整理(界面和操作分离),有很多注释部分也有参考价值,告辞!
