在Mac上安装FFMPEG

Question

我尝试使用

通过自制软件安装ffmpeg

brew install ffmpeg

当我尝试将ffmpeg导入Python时，我收到以下错误：

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named ffmpeg

我可以确认ffmpeg是通过brew列表安装的。我不确定为什么python没有认识到它。

您安装的是class func TestConnection(_ urlBase: String, usingCommand command: String, completionHandler: @escaping (Bool) -> Void) { let urlString = urlBase + "/" + command var IsValidConnection = false guard let url = URL(string: urlString) else { completionHandler(IsValidConnection) return } URLSession.shared.dataTask(with: url) { (data, response, error) in //App blows up when running this block of code. //Doesn't return. App crashes/locks up guard error == nil else { completionHandler(false) return } //App works as expected when running code below guard let _: HTTPURLResponse = response as? HTTPURLResponse else { completionHandler(false) return } let serverResponse = response as! HTTPURLResponse if serverResponse.statusCode == 200 { IsValidConnection = true } completionHandler(IsValidConnection) }.resume() } 命令行工具和各种C库。它不包含任何Python绑定。如果您要安装ffmpeg-python，请运行/usr/local/bin/ffmpeg。
