This script helps to download drm protected dash stream [if key is known] and output to a video mp4 file

Drm Dash stream downloader

Description

Downloads MPEG-DASH Cenc based drm contents by parsing the manifest if the keyID and key is known.

Requirements

1. You would need to download ffmpeg and mp4decrypter from Bento4 SDK and ensure they are in path(typing their name in cmd invokes them).
2. Dash-IF conforming Manifest file having information about the cenc keyID ,PSSH box information.
3. Basic python knowledge to edit the script's manifest parser function according to your manifest and set your prefered download location.

Usage

1. Clone the repository
2. Install the requirements in requirements.txt using pip
3. Find the manifest(mpd) file you would want to download and copy its url (Use Devtools if in a browser.)
4. View the mpd file and check if it uses single mp4 segment or multi segments($Number_xx$.mp4)
5. If it is of multi segments then use dashdownloader_multisegment.py
6. Paste the mpd url in the script at the bottom inside the standalone check condition in mpd variable.
7. Run the script after checking requirements are satisfied.

Note

CBCS and SAMPLE-AES contents need to be manually analyzed and the script has to be modified for decrypting those content.

Error in Download

Bro Sometimes Error occurred

Could you, Please, make Windows Binaries!?

Hello, "Jayapraveen"!

Could you, Please, build windows binaries, which can be used and under Windows XP 64bit version?
And there to be included all the nessesery files (like "mp4decrypter", FFMpeg and others needed). One to can set if the stream is multi-segmented or not. I mean all the options to be configurable. The possibility to inititally modify the encryption method, keys and so on!

Thank You!!!

Peter

Wiki

A bit more info on a how to would be great. Even if it's a one line example of usage.

Getting can only concatenate str (not "NoneType") to str

[KeyError] Key not found

def decrypt(filename,keyid,video_title):
    try:
        key = keyfile[keyid]
        print(key)
        os.system(f"ffmpeg -y -decryption_key {key} -i {filename} -codec copy -metadata title={video_title} dec_{filename}")
    except KeyError as error:
        print("Key not found")
        exit()

The above function tries to fetch the decryption key from the "keyfile.json" file with the Key ID.

Where do we get the decryption key?

How does this program work?
