Download Videos from Graphy or Spayee

Requirements:

ffmpeg
openssl
wget

Step 1: Getting the video data

Play the video you want to download
Open Developer Tools (Ctrl+Shift+I in Chrome)
Go to Network tab
Now reload the browser
Search for ".m3u8" :

Look for index.m3u8 or master.m3u8. Here I found index.m3u8, click on that:

Go to Preview tab
Copy the file name of resolution you want to download:

Search again by that file name:

Open that and go to headers tab then copy the request url:

Open it in a new tab and download the file.

The file you have just downloaded, it has all of the .ts files. (Don't need to know what is .ts :^)

Those ts are encrypted. So you have to decrypt that. You need a key to decrypt that. You will get the key in the source code. Let's see..

Step 2: Getting the decryption key

Go to the sources tab in the Developer Tools
Look for 'cdn.jsdelivr.net':

Expand that, expand npm, open the hls.js file
Pretty print the file:

Now search for 'this.decryptkey', and find the code like this then put a breakpoint at that line, after that pause the script:

Reload the browser, now the browser might not finish the loading. Don't worry
Go to console tab of the Developer tools, clear the console:

Paste this code and hit enter:

Array.prototype.map.call(this.decryptkey, x => ('00' +
x.toString(16)).slice(-2)).join('')

The output you will get is the key you need in order to decrypt the video files

Step 3: Downloading all of the .ts files

Now you have to download all of the .ts files

Open terminal (cmd for windows)
Open the m3u8 file you downloaded
Check the .ts files:

For me the m3u8 file link is - https://d2qny97nu4rj64.cloudfront.net/spees/w/o/62849985/v/6339af82c819310/u/636fd9da2ec532/t/99cc6d32e738/p/assets/videos/628222f8bf2b49985/2022/10/02/6339a819310/hls_500k_.m3u8 Note: Values have been changed for privacy

Remove the last parameter of the URL: https://d2qny97nu4rj64.cloudfront.net/spees/w/o/62849985/v/6339af82c819310/u/636fd9da2ec532/t/99cc6d32e738/p/assets/videos/628222f8bf2b49985/2022/10/02/6339a819310/
Add the first ts filename you found from m3u8 file and replace the text which changes at every ts with $i: https://d2qny97nu4rj64.cloudfront.net/spees/w/o/62849985/v/6339af82c819310/u/636fd9da2ec532/t/99cc6d32e738/p/assets/videos/628222f8bf2b49985/2022/10/02/6339a819310/hls_500k_$i.ts
Paste this to the terminal/cmd, replace with the link you just made by adding .ts: See how many ts do you have and replace the <limit_of_the_ts> with that value

for i in {1..<limit_of_the_ts>}; do wget "<link>" -O ->> "encrypted.ts"; done;

After editing hit enter. All of the ts will be downloaded now.

Decrypt that ts to mp4 now:

sh
openssl enc -aes-128-cbc -nosalt -d -in encrypted.ts -K '<the_key_you_got_in_console>' -iv '<iv_in_m3u8_file_without_0x>' > decrypted.mp4

Boom! You got the video but without audio. :)

To get the audio do the same thing -

First find the audio by searching

https://d2qny97nu4rj64.cloudfront.net/spees/w/o/62849985/v/6339af82c819310/u/636fd9da2ec532/t/99cc6d32e738/p/assets/videos/628222f8bf2b49985/2022/10/02/6339a819310/hls_audio_0_$i.ts

for i in {1..<limit_of_the_ts>}; do wget "<link>" -O ->> "encrypted.ts"; done;

sh
openssl enc -aes-128-cbc -nosalt -d -in encrypted.ts -K '<the_key_you_got_in_console>' -iv '<iv_in_m3u8_file_without_0x>' > audio.aac

Step 4 : Finish the process

Combine the audio and the video

sh
ffmpeg -i video.mp4 -i audio.aac -c copy output.mp4
