yt-dlp-bot

Simple and reliable YouTube Download Telegram Bot.

Version: 0.9. Release details.

😂 Features

• Download videos from any yt-dlp supported website to your storage
• Upload downloaded videos to the Telegram chat
• Trigger video download by sending link to an API
• Track download tasks via API

⚙ Quick Setup

1. Create Telegram bot using BotFather and get your token
2. Get your Telegram API Keys (api_id and api_hash)
3. Find your Telegram User ID
4. Copy app_bot/config-example.yml to app_bot/config.yml
5. Write token, api_id, api_hash to app_bot/config.yml by changing respective placeholders
6. Write your Telegram user id to the allowed_users -> id by replacing dummy value and change or remove forward_group_id value (if you want to forward the video to some group when upload is enabled)
7. Check the default environment variables in envs/.env_common and change if needed
8. Video storage path (STORAGE_PATH environment variable) is located in the envs/.env_worker file. By default, it's /filestorage path inside the container. What you want is to map the real path to this inside the docker-compose.yml file for worker service, e.g. if you're on Windows, next strings mean container path /filestorage is mapped to real D:/Videos so your videos will be saved to your Videos folder.

     worker:
       ...
       volumes:
         - "D:/Videos:/filestorage"
   

9. If you want your downloaded video to be uploaded back to the Telegram, set upload_video_file config variable for your user in the app_bot/config.yml to True

🏃 Run

# Build base image
docker compose build base-image

# Build and run all services in detached mode
docker compose up --build -d -t 0 && docker compose logs --tail 100 -f

# Stop all services
docker compose stop -t 0

Your telegram bot should send you a startup message: ✨ <YOUR_BOT_NAME> started, paste a video URL to start download and that's it. After pasting video URL(s) bot will send you appropriate message whether they were downloaded or something went wrong.

💻 Advanced setup

1. If you want to change yt-dlp download options, go to the app_worker/ytdl_opts directory, copy content from default.py to user.py and modify as you wish by checking available options .
2. Default max simultaneous video downloads by worker service is 2. Change the MAX_SIMULTANEOUS_DOWNLOADS variable in envs/.env_worker to desired value but keep in mind that default mounted volume size is 7168m (7GB) in docker-compose.yml so it may be not enough if you download a lot of large videos at once.
3. yt-dlp will try to download video thumbnail if it exists. In other case Worker service (particularly the FFmpeg process) will make a JPEG thumbnail from the video. It's needed when you choose to upload the video to the Telegram chat. By default, it will try to make it on the 10th second of the video, but if the video is shorter, it will make it on video length / 2 time point because the FFmpeg process will error out. Change the THUMBNAIL_FRAME_SECOND variable if needed in the envs/.env_worker file.
4. Max upload file size for non-premium Telegram user is 2GB (2147483648 bytes) which is reflected in the example config app_bot/config-example.yml. If the configured user is the premium user, you're allowed to upload files up to 4GB (4294967296 bytes) and can change the default value stored in the upload_video_max_file_size config variable.

🛑 Failed download

If your URL can't be downloaded for some reason, you will see a message with error details
