Question

我有一个由PyQt编写的程序，该程序通过绑定libvlc来播放视频。

import sys
import os
import vlc

from PySide2.QtGui import *
from PySide2.QtCore import *
from PySide2.QtWidgets import *

class vlc_demo(QWidget):
    def __init__(self):
        super(vlc_demo, self).__init__()
        self.__ui__()
        self.__load__()

    def __ui__(self):

        self.setFixedSize(800,600)
        t_lay_parent = QVBoxLayout()
        self.m_label_media = QLabel()
        t_lay_bottom = QHBoxLayout()
        self.m_button_one = QPushButton("one")
        self.m_button_too = QPushButton("too")
        self.m_button_three = QPushButton("three")
        t_lay_bottom.addWidget(self.m_button_one)
        t_lay_bottom.addWidget(self.m_button_too)
        t_lay_bottom.addWidget(self.m_button_three)

        self.m_button_one.clicked.connect(self.slt_one)
        self.m_button_too.clicked.connect(self.slt_too)
        self.m_button_three.clicked.connect(self.slt_three)

        t_lay_parent.addWidget(self.m_label_media)
        t_lay_parent.addLayout(t_lay_bottom)
        self.setLayout(t_lay_parent)

    def __load__(self):
        self.m_instance = vlc.Instance()
        self.m_player = self.m_instance.media_player_new()
        self.m_win_id = self.m_label_media.winId()
        if sys.platform.startswith('linux'):  # linux
            self.m_player.set_xwindow(self.m_win_id)
        elif sys.platform == "win32":  # windows
            self.m_player.set_hwnd(self.m_win_id)
        elif sys.platform == "darwin":  # mac
            self.m_player.set_nsobject(self.m_win_id)

    def slt_one(self):
        self.m_label_media.show()
        media = self.m_instance.media_new("1.mp4")
        self.m_player.set_media(media)
        self.m_player.play()

    def slt_too(self):
        self.m_label_media.show()
        media = self.m_instance.media_new("2.mp4")
        self.m_player.set_media(media)
        self.m_player.play()

    def slt_three(self):
        self.m_label_media.hide()

if __name__ == "__main__":
    app = QApplication(sys.argv)
    win = vlc_demo()
    win.show()
    sys.exit(app.exec_())

在Windows下，将以下文件和目录复制到VLC媒体播放器目录中。该程序可以在没有VLC媒体播放器的计算机上运行。

 - libvlc.dll
 - libvlccore.dll
 - plugins

在CentOS7下，没有安装VLC媒体播放器就可以运行该程序吗？

我相信您可能会使用AFAIU专为此设计的Snapcraft零件。

对于VLC为https://github.com/videolan/vlc/blob/master/extras/package/snap/snapcraft.yaml

如何在CentOS7下构建静态libvlc？
