Some did have some functionality but seeking (one of the most important methods to grab snapshots) did not work without decoding the whole video up to this point which of course took too long. My second approach was to use one of the many FFmpeg wrappers which wrap the FFmpeg DLLs directly into C#. I did some research and found out that there seems to be an interface missing in these codecs that is used by ActiveX. The MediaDet class could not handle these types although I had the correct codecs installed. a MP4 container with a H.264 video and AAC audio codec or a simple FLV video. The disappointment came when I tried other video formats than my standard test video (AVI DivX MP3), e.g. I managed to grab frames at specified positions after editing the COM interface - I do not exactly remember where but I had to replace a byte parameter with a IntPtr one. I tried to use ActiveX and its COM interface in C#. Luckily that skill let me reach my goal for the video library - and it is highly improvised. Coming with working on the Compact Framework and different mobile devices comes a resignation, that if you want to do something the Windows OS on a device does not offer natively, you end up improvising a lot. I am using C# at work - mainly C# 3.5 CF - and to my shame I do not have much experience with other programming languages. This article will be about taking snapshots from almost any video file. Information also means video snapshots so you can instantly see what video file it is. I am creating a library for my video files and want it to be capable of extracting as many information from a file as possible so the user (mainly me) can be as lazy adding new videos as possible. If you're looking for a PInvoke wrapper for FFmpeg, have a look at my new article about that: Invoke FFmpeg to export frames Introduction
