Simple-stupid telegram bot that can use watermark image overlay over video input with ffmpeg.
Uses long-polling, which is not ideal (webhook would be better), but just works.
Supports localization: Ukrainian (uk) and English (en), could be configured via config.env file or env variables (with BOT_ prefix).
Working example: @odarka_watermarka_bot

• Go
• Register bot with @BotFather
• ffmpeg should be installed
  • macos (with brew, fyi: may require xcode-select --install)

        brew install ffmpeg

  • ubuntu

        sudo apt install ffmpeg

• Configure config.env (you can check sample.env as an example):
  • set TELEGRAM_TOKEN (could be obtained from @BotFather)
  • set ENVIRONMENT - if it is dev - debug logs will be displayed
  • set LOCALE - supports en for english and uk for ukrainian, uk by default.

    go run .

binary will be available in bin folder.

• for ubuntu

      GOOS=linux GOARCH=amd64 go build -ldflags="-s -w" -o bin/tgbot-watermark

• for macos

      GOOS=darwin GOARCH=arm64 go build -ldflags="-s -w" -o bin/tgbot-watermark
