如何在 Tkinter 中播放视频文件？

Question

有没有办法播放 AVI、MP4 等？

我尝试使用 PyMedia，但显然它只适用于 Pygame。

我的问题的解决方案是什么？

Answer 1

您可以使用 python-gstreamer 来播放视频（这适用于 Linux 上的我，但它也应该适用于 Windows）。这需要 python-gstreamer 和 python-gobject，我建议您用这个一体化安装程序。

这是代码：

import os
import sys
import Tkinter as tkinter

import gobject
import gst

def on_sync_message(bus, message, window_id):
        if not message.structure is None:
            if message.structure.get_name() == 'prepare-xwindow-id':
                image_sink = message.src
                image_sink.set_property('force-aspect-ratio', True)
                image_sink.set_xwindow_id(window_id)

gobject.threads_init()

window = tkinter.Tk()
window.geometry('500x400')

video = tkinter.Frame(window, bg='#000000')
video.pack(side=tkinter.BOTTOM,anchor=tkinter.S,expand=tkinter.YES,fill=tkinter.BOTH)

window_id = video.winfo_id()

player = gst.element_factory_make('playbin2', 'player')
player.set_property('video-sink', None)
player.set_property('uri', 'file://%s' % (os.path.abspath(sys.argv[1])))
player.set_state(gst.STATE_PLAYING)

bus = player.get_bus()
bus.add_signal_watch()
bus.enable_sync_message_emission()
bus.connect('sync-message::element', on_sync_message, window_id)

window.mainloop()

利用 tkvideoplayer version>=2.0.0 库，它可以帮助您播放、暂停、查找、获取视频的元数据等。

pip install tkvideoplayer

示例示例：

import tkinter as tk
from tkVideoPlayer import TkinterVideo

root = tk.Tk()

videoplayer = TkinterVideo(master=root, scaled=True)
videoplayer.load(r"samplevideo.mp4")
videoplayer.pack(expand=True, fill="both")

videoplayer.play() # play the video

root.mainloop()

以下代码适用于 Ubuntu 16.04 下的 GStreamer 1.0 和 Python 3。它还允许在单个窗口中堆叠成一列的八个视频播放器。 （声道只是混合在一起。）

libav/ffmpeg 分支在 Ubuntu 14.04 下产生了问题，这些问题似乎在 16.04 下得到了解决。请注意，除了 gstreamer1.0-plugins-* 之外，您还需要 gstreamer1.0-libav 包。

该代码基于 @koehlma 2011 年的答案构建，该答案假设使用 GStreamer 0.10 和 Python 2。

import sys
import os

if sys.version_info[0] < 3:
    import Tkinter as tkinter
else:
    import tkinter

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

# Needed for set_window_handle():
gi.require_version('GstVideo', '1.0')
from gi.repository import GstVideo

def set_frame_handle(bus, message, frame_id):
    if not message.get_structure() is None:
        if message.get_structure().get_name() == 'prepare-window-handle':
            display_frame = message.src
            display_frame.set_property('force-aspect-ratio', True)
            display_frame.set_window_handle(frame_id)

NUMBER_OF_FRAMES = 8 # with more frames than arguments, videos are repeated
relative_height = 1 / float(NUMBER_OF_FRAMES)

# Only argument number checked, not validity.
number_of_file_names_given = len(sys.argv) - 1
if number_of_file_names_given < 1:
    print('Give at least one video file name.')
    sys.exit()
if number_of_file_names_given < NUMBER_OF_FRAMES:
    print('Up to', NUMBER_OF_FRAMES, 'video file names can be given.')
file_names = list()
for index in range(number_of_file_names_given):
    file_names.append(sys.argv[index + 1])

window = tkinter.Tk()
window.title("Multiple videos in a column using Tk and GST 1.0")
window.geometry('480x960')

Gst.init(None)
GObject.threads_init()

for number in range(NUMBER_OF_FRAMES):
    display_frame = tkinter.Frame(window, bg='')
    relative_y = number * relative_height
    display_frame.place(relx = 0, rely = relative_y,
            anchor = tkinter.NW, relwidth = 1, relheight = relative_height)
    frame_id = display_frame.winfo_id()

    player = Gst.ElementFactory.make('playbin', None)
    fullname = os.path.abspath(file_names[number % len(file_names)])
    player.set_property('uri', 'file://%s' % fullname)
    player.set_state(Gst.State.PLAYING)

    bus = player.get_bus()
    bus.enable_sync_message_emission()
    bus.connect('sync-message::element', set_frame_handle, frame_id)

window.mainloop()

最简单的方法是使用 tkVideo

来安装它，

pip install tkVideo

这个脚本将向您展示它如何轻松工作！

from tkinter import *
from tkvideo import tkvideo

root = Tk()
my_label = Label(root)
my_label.pack()
player = tkvideo("C:\\path\\to\\video.mp4", my_label, loop = 1, size = (1280,720))
player.play()

root.mainloop()

这是 PyPI 链接以获取更多信息。

Answer 5

koehlma的答案已经过时了。 “Tkinter”应该是“tkinter”； “商品及服务税”应为“商品及服务税”； “playbin2”应该是“playbin”。 “STATE_PLAYING”应为“State.PLAYING”。以下设置和代码适用于截至 2022 年 4 月 5 日的 Debian 11。

首先，您需要安装的软件包是

apt install python3-gi python3-gst-1.0 python3-tk

并且代码应更新为：

import os
import sys
import tkinter as tkinter

import gi
gi.require_version('Gst', '1.0')
from gi.repository import Gst as gst
from gi.repository import GObject as gobject

def on_sync_message(bus, message, window_id):
        return
        # message does not have structure field any more.
        if not message.structure is None:
            if message.structure.get_name() == 'prepare-xwindow-id':
                image_sink = message.src
                image_sink.set_property('force-aspect-ratio', True)
                image_sink.set_xwindow_id(window_id)

gobject.threads_init()

window = tkinter.Tk()
window.geometry('500x400')

video = tkinter.Frame(window, bg='#000000')
video.pack(side=tkinter.BOTTOM,anchor=tkinter.S,expand=tkinter.YES,fill=tkinter.BOTH)

window_id = video.winfo_id()

gst.init(None)
player = gst.ElementFactory.make('playbin', 'player')
player.set_property('video-sink', None)
player.set_property('uri', 'file://%s' % (os.path.abspath(sys.argv[1])))
player.set_state(gst.State.PLAYING)

bus = player.get_bus()
bus.add_signal_watch()
bus.enable_sync_message_emission()
bus.connect('sync-message::element', on_sync_message, window_id)

window.mainloop()

我最近制作了一个包来做到这一点，无边框视频播放器。它还同步播放音频。

pip install bvPlayer

代码：

from bvPlayer import bvPlayer

bvPlayer("file.mp4")
