关于树莓派4B使用pyglet播放视频报错的问题

TrinityLeaves

最近我有个需求需要在树莓派上播放视频
网上基本是两种，一个是cv2，一个是pyglet
我用cv2写的时候发现播放速度很难对得上(网上居然都是直接waitkey里面写死的时间……害人不浅)
改用pyglet模块，在windows上已经实现了，结果移到树莓派里面使用直接报错了。
我发现甚至最简单的pyglet播放视频程序也会报错……
就如下这么播放：

[Python] 纯文本查看 复制代码

import pyglet
window = pyglet.window.Window()
player = pyglet.media.Player()
source = pyglet.media.load('E:\\FFOutput\\a5.mp4')
player.queue(source)
player.play()

@window.event
def on_draw():
    image=player.get_texture()
    if image is not None:
        image.blit(0, 0)
pyglet.app.run()

报的错是BUS ERROR

>>> %Run test.py

Backend terminated or disconnected.Fatal Python error: Bus error

请大佬们看一下怎么解决，使用的是树莓派4B，已经apt update upgrade过了
如果有其他正常播放视频的解决方案（需要全屏，并且能获取当前播放时间和调用方法，循环播放）也可以
第一次发帖，如果有哪里不对的地方请指出

推荐vlc播放器

今天尝试了一下vlc……就写了个时间跳转就报错了

player=vlc.MediaPlayer("XXXXX视频路径")
就如下这么写  调用也会报错
player.set_time(1)

[91210728] main decoder error: buffer deadlock prevented

在windows上运行正常，树莓派里各种报错
吐槽一下：怎么用啥啥报错= =，大佬们用树莓派的时候都是怎么开发的？

两个系统编码可能不太一致，而且跨平台一些模块的用法也不一样，建议开发都在linux中开发

谢谢，不过我在Linux虚拟机和官方给的镜像做的虚拟机中运行都是正常的，实机上就会报错。
已经没用python写了，用C++和mplayer做了
