How to grab frame from .mov file in c#.net by using DirectShow.net

推荐答案

DirectShow和DirectShow.NET不作任何特殊与 .MOV 文件。通常，您可以创建一个过滤器图，您管理的样品采集卡过滤器，它的回调为您提供了通过视频流的帧。

DirectShow and DirectShow.NET don't make it any special with .MOV files. You typically create a filter graph with a Sample Grabber filter that you manage, and its callback gives you frames of video stream that passes through.

您可能想看看DirectShow.NET DxScan样本，\样本\编辑\ DxScan。它抓住帧从一个给定的电影文件。

You might want to look at DxScan sample in DirectShow.NET, \Samples\Editing\DxScan. It grabs frames from a given movie file.

Most of the work is done in ISampleGrabberCB.BufferCB. See the comments there. Also, the algorithm used to scan for black frames isn't as efficient as it could be. However, the samples gives you an idea of how this could be done.
