跨平台C＃Media API [英] Cross Platform C# Media API

问题描述

我正在尝试在mono / .net对象中定义一个VideoFile，以便我可以调用

I'm trying to define a VideoFile in mono/.net object such that I can call

var file = new VideoFile(filepath);
file.VideoDuration 

是否有可以跨平台工作的库（os或商业） mono / .net可以提供诸如VideoDuration之类的信息。只有当我这样做的时候才会包装ffmpeg.exe并读取控制台out-stream。

Is there a library (os or commercial) which will work across platforms mono/.net which can provide information such as VideoDuration. The only though I have had on this currently is to wrap ffmpeg.exe and read the console out-stream.

推荐答案

GStreamer 是一个很好的选择，它是一个跨平台的多媒体框架。还有一些绑定可以满足您的需求：通过.NET API访问您需要的信息（视频文件的长度）： GStreamerSharp 。

GStreamer is good option, it's a cross platform multimedia framework. And there are bindings that would meet your needs: access the information you require (length of a video file) via a .NET API: GStreamerSharp.

的确，我们实际上使用它在 Banshee Project ，一个用C＃编写的媒体播放器（这是Ubuntu中捆绑的默认音乐播放器）。

Indeed, we actually use it in the Banshee Project, a media player written in C# (which is the default music player bundled in Ubuntu).

BTW，GStreamer的设计方式是编解码器是插件，所以你有一个抽象的内部（即ffmpeg）其他插件可以满足，取决于你的许可/格式需求。

BTW, GStreamer is architected in a way that codecs are plugins, so you have an abstraction between the internals of them (i.e. ffmpeg) which other plugins could fulfill depending on your licensing/format needs.
