groupcall

Overview ¶

Binary groupcall joins a Telegram group voice chat and streams an MP3 file into it as audio.

It logs in via QR code (with 2FA fallback), resolves a supergroup/channel by username, joins its active voice chat and streams the MP3 (transcoded to Opus with ffmpeg) until the file ends.

Usage:

APP_ID=... APP_HASH=... SESSION_FILE=session.json \
    go run ./examples/groupcall -chat @mygroup -audio song.mp3

The group must already have a voice chat started. Pass -test to run against Telegram's test servers instead of production. Requirements: ffmpeg on PATH (with libopus).
