Telegram Video Download Bot (Direct API + MTProto)

A high-performance Telegram bot that downloads videos from Dailymotion and Animecube at your preferred resolution, bypassing Telegram's standard 50MB file size limit.

Key Features

• Direct API Integration: Interacts directly with the savethevideo.com v02 API for format extraction and server-side conversion.
• MTProto Support: Uses gramJS to upload files up to 2GB, bypassing the standard Bot API limitations.
• Interactive UI: Provides inline buttons for users to select their desired resolution.
• OOM Stability: Uses disk-based streaming to handle large video files without crashing the Node.js process.
• Rate-Limit Mitigation: Implements randomized User-Agent headers and automatic retry logic for 429 errors.

How it Works

1. Extraction: The bot sends the URL to the API to identify all available formats.
2. Selection: Formats are sorted by resolution (lowest first) and presented via Inline Buttons.
3. Conversion: The API performs server-side conversion to provide a direct MP4 link.
4. Delivery: The bot streams the MP4 to a temporary file and uploads it to the user via MTProto.
