问题描述
正如标题所述,我正在尝试使用 PySimpleGUI 创建一个基本的流链接 GUI。
我有
[gui.Text('Stream link:'),gui.InputText()],
和一堆其他代码(尚未实现的选项),这些代码将流链接作为输入,runcommand('streamlink ' + values[0] + ' best -o output.ts')
使用流链接以最佳质量将流下载到 output.ts。
运行命令是:
def runcommand(cmd,timeout=None,window=None):
os.path.dirname(os.path.realpath(__file__))
p = subprocess.Popen(cmd,shell=True,stdout=subprocess.PIPE,stderr=subprocess.STDOUT)
output = ''
for line in p.stdout:
line = line.decode(errors='replace' if (sys.version_info) < (3,5) else 'backslashreplace').rstrip()
output += line
print(line)
window.Refresh() if window else None
retval = p.wait(timeout)
return (retval,output)
if __name__ == '__main__':
main()
(我找到了 here)
这是这样工作的:
[cli][info] Found matching plugin youtube for URL
[cli][info] Available streams: audio_mp4a,audio_opus,144p (worst),240p,360p,480p,720p,720p60,1080p60 (best)
[cli][info] opening stream: 1080p60 (muxed-stream)
error: Failed to open output: output.ts ([Errno 13] Permission denied: 'output.ts')
[cli][info] Closing currently open stream...
如您所见,当我通过 runcommand 运行 streamlink 时,它收到一个权限被拒绝错误。我试图在运行 .py 脚本的同一目录中获取输出文件,但我认为 runcommand 可能指定了一个我无权写入的目录。
我不知道如何为此命令指定目录,有人可以帮忙吗?
解决方法
我在与我的 scripy 文件相同的目录下得到了一个 output.ts。 链接地址输入 Input,然后“go”点击。

elif event == 'Go':

window.close()

如果文件区域存在,

这里,runCommand
需要很长时间才能工作,因此 GUI 可能没有响应。建议使用多线程。
