Configuration

The app is configured via environment variables listed in this file. Here is a minimal example .env file:

AHM_HOST=169.42.0.1
BOT_TOKEN=<your_telegram_bot_token>
ADMIN_USERS=<some_user_id>,<some_other_user_id>,...
PLAYER_COMMAND="ffplay -nodisp -autoexit %f"

Player command examples

Play audio on speaker (Windows)

• install ffmpeg: winget install --id=Gyan.FFmpeg -e

First, get the id of the Speaker (using powershell):

$AudioDeviceFilter="" # fill me in to filter output
Get-ItemProperty "HKLM:\SYSTEM\CurrentControlSet\Enum\SWD\MMDEVAPI\*" | Where-Object {($_.FriendlyName -Match $AudioDeviceFilter) -and ($_.PSChildName -Match "0\.0\.0")} | Select-Object -Property FriendlyName,PSChildName

Copy the PSChildName from the output and use it like this:

PLAYER_COMMAND='"C:\Program Files\VideoLAN\VLC\vlc.exe" -I dummy --dummy-quiet --no-one-instance --mmdevice-audio-device {0.0.0.00000000}.{some-guid} --play-and-exit %f'

This GUID may also be visible somwhere in Windows Device Manager, one may double check that the device is correct.
