Extract Videos and PDFs from Protected

🔐 Project Overview:

I’m looking for a senior-level developer experienced in reverse engineering and Windows application analysis to create a solution that can extract original video files (e.g., MP4 or native format) and PDF documents from a DRM-protected desktop app.

⚠️ I already have full access via valid login and password, and I can view all the content (videos and PDFs) inside the app.The goal is to extract the actual files, not screen recordings or screenshots.

✅ What I need you to build:

A tool, script, or process that:
Extracts videos in original quality (not recorded, not screen-captured)
Downloads or reconstructs PDF files visible in the app
Runs locally on a Windows PC

Absolutely no screen recording.I want to save the actual video and PDF files, as they exist within the app or its memory/cache.

You may use:
Python, C#, C++, Rust, or any suitable language
Techniques like memory analysis, API hooking, disk/cache inspection, network interception, etc.



⚙️ Technical Context:
The application is a Windows-only desktop app
Content (videos and PDFs) is accessible only inside the app
The app prevents:
Screen sharing (e.g., Google Meet shows a black screen)
Screen capture (PrintScreen results in black image)
Recording (OBS and other tools do not work)
Traffic sniffing (no usable URLs found via TubeDigger, Fiddler, or URL Snooper)
Likely uses:
DRM (Widevine, PlayReady, FairPlay or custom)
Direct rendering APIs (DirectShow, Media Foundation)
Encrypted or temporary cache storage

💼 Ideal Developer Profile:

Strong experience in reverse engineering (IDA Pro, Ghidra, x64dbg, etc.)
Skilled in Windows API hooking, process memory inspection
Familiar with DRM systems and protected streaming
Able to extract or reconstruct media content from RAM, disk, or internal calls

📁 Expected Deliverables:

A functional tool or script that:
Extracts video and PDF files shown in the app
Saves them to disk in original format (MP4, PDF, or raw)
Basic documentation (how to use the tool)
