videohash 1.0.7

videohash is a video fingerprinting / video hashing tool written in Python

VideoHash

A simple Video Hashing Library

---

Installation

You must have ffmpeg installed to use this library.

➤ Install FFmpeg

Linux

• APT

sudo apt-get update
sudo apt install ffmpeg

• Snap

sudo snap install ffmpeg

Windows

Steps are based on video.stackexchange.com/a/20496, please note that the download site is outdated as of January 2021.

• Download the release full variant from https://www.gyan.dev/ffmpeg/builds/. You can download any variant you want, but I prefer the full release.
• Decompress the archive.
• Copy the bin directory from the decompressed folder, and paste inside C:\Program Files\ffmpeg\.
• Right click on "This PC" and navigate to Properties > Advanced System Settings > Advanced tab > Environment Variables.
• In the Environment Variables window, click the "Path" row under the "Variable" column, then click Edit.
• Click New and add C:\Program Files\ffmpeg\bin\to the list.
• Click Ok on all the windows we just opened up. (Answer postive)

If you still have doubts read the answer https://video.stackexchange.com/a/20496, it has images to guide you.

macOS

brew install ffmpeg

Install videohash

• Using pip:

pip install videohash

• Install directly from GitHub:

pip install git+https://github.com/akamhy/videohash.git

Usage

>>> import videohash
>>> hash1 = videohash.from_url("https://raw.githubusercontent.com/akamhy/videohash/main/assets/rocket.mkv")
>>> str(hash1)
'fe3fffff8ff80000'
>>> hash2 = videohash.from_url("https://www.youtube.com/watch?v=PapBjpzRhnA")
>>> str(hash2)
'fe3fffff9ff80000'
>>>
>>> diff = hash1 - hash2
>>> diff
1
>>>
>>> hash3 = videohash.from_url("https://www.youtube.com/watch?v=_T8cn2J13-4")
>>> diff = hash1 - hash3
>>> diff
29
>>> str(hash3)
'3cffff00000081f0'
>>>
>>> #hash4 file is hash1 file downloaded locally. NOTE :  Use absolute path
>>> hash4 = videohash.from_path("/home/akamhy/Downloads/rocket.mkv")
>>> diff = hash4 - hash1
>>> diff
0
>>>

_{Run the above code @ https://repl.it/@akamhy/video-hash-example#main.py}

• https://raw.githubusercontent.com/akamhy/videohash/main/assets/rocket.mkv is copy of https://www.youtube.com/watch?v=PapBjpzRhnA, and are about the Artemis program and SLS rocket.

• https://www.youtube.com/watch?v=_T8cn2J13-4 is an entirely distinct video also about the Artemis program.

• Notice that the difference of hash1 and hash2 is 1, but the difference between hash1 and hash3 is 29.

• The difference of hash1 and hash2 is not 0 as the file in this repository is slightly modified and downscaled.

• A collage of frames is generated and imagehash(Average hashing) of this collage is videohash for the full video.

You can change the algorithm used to generate the hash of the collage via the image_hash argument. The default algorithm is average_hash.

>>> hash = videohash.from_url("https://www.youtube.com/watch?v=PapBjpzRhnA", image_hash="crop_resistant_hash")
>>> hash = videohash.from_path("/home/akamhy/Downloads/rocket.mkv", image_hash="phash")

➤ Algorithms supported

• average_hash
• phash
• dhash
• whash
• colorhash
• crop_resistant_hash

videohash is using https://github.com/JohannesBuchner/imagehash to use these image-hashing algorithms.
