Previous mentioned extract picture meta information Exif, of course, there is a class of audio and video files, too many valuable storage metadata, it would open in the end chant, although the process is very hard to find their own ups and downs, we have to see harvest, just under a lot of communication, so that the previous work can be more valuable.
Excel catalytic function corresponding to achieve this post: 83 Wave - specific information file folder information traversing particular image, audio and video https://www.jianshu.com/p/ad98adc64f0b
Extract audio and video metadata, uses MediaToolkit libraries than other complex programs, this most friendly to me this amateur developers, and finally was fortunate enough to meet it.
Directly on the code, is also just a few lines of code can get the core information.
private void AddMediaInfo(DataRow dr, string filePath)
{
try
{
using (var engine = new Engine())
{
var inputFile = new MediaToolkit.Model.MediaFile { Filename = filePath };
engine.GetMetadata(inputFile);
var videoData = inputFile.Metadata.VideoData;
var audioData = inputFile.Metadata.AudioData;
dr[ColNameOfVideoDuration] = Math.Round(inputFile.Metadata.Duration.TotalSeconds / 60.0, 2);
if (videoData != null)
{
dr[ColNameOfVideoFormat] = videoData.Format;
string sizeStr = videoData.FrameSize;
dr[ColNameOfVideoWidth] = sizeStr.Split('x')[0];
dr[ColNameOfVideoHeight] = sizeStr.Split('x')[1];
}
if (audioData != null)
{
dr[ColNameOfAudioFormat] = audioData.Format;
dr[ColNameOfAudioBitRateKbs] = audioData.BitRateKbs;
dr[ColNameOfAudioSampleRate] = audioData.SampleRate;
}
}
}

取名催化剂，因Excel本身的强大，并非所有人能够立马享受到，大部分人还是在被Excel软件所虐的阶段，就是头脑里很清晰想达到的效果，而且高手们也已经实现出来，就是自己怎么弄都弄不出来，或者更糟的是还不知道Excel能够做什么而停留在不断地重复、机械、手工地在做着数据，耗费着无数的青春年华岁月。所以催生了是否可以作为一种媒介，让广大的Excel用户们可以瞬间点燃Excel的爆点，无需苦苦地挣扎地没日没夜的技巧学习、高级复杂函数的烧脑，最终走向了从入门到放弃的道路。
最后Excel功能强大，其实还需树立一个观点，不是所有事情都要交给Excel去完成，也不是所有事情Excel都是十分胜任的，外面的世界仍然是一个广阔的世界，Excel只是其中一枚耀眼的明星，还有其他更多同样精彩强大的技术、工具等。*Excel催化剂也将借力这些其他技术，让Excel能够发挥更强大的爆发！
