Analyze video content, create an index on (with a search engine?)

Question

How can I create an Index on thousands of video files? Analyze the audio track of a video file and write this somewher, like a tag.

Thanks!

Answer 1

By traversing the directory structure and obtaining information about the streams from it's container format. Without knowing OS and programming language of choice, I cannot be more specific.

Answer 2

Your question is too broad, I am afraid. The only answer I can give you would be vague. How? Depending on what are these files and how granular your indexing should be, you have few choices.

1. By file name, compression method, stream properties. The obvious one and fairly easy to implement. Especially if these files (which I doubt) support MPEG-7.
2. By analyzing the contents. It is hard. Very, very hard. It would require adopting technique known as Computer Vision. Possible solutions would involve Machine Learning, probably Neural Networks. Fairly impossible for single (even genius) programmer.
