VoiceConnection#playFile() crashes bot with 'TypeError: Bad argument'

[Ratismal]

Hi,

I've been trying to make a simple music bot with Eris for learning experience. The objective is to have it join a voice channel, play an existing song file, and leave. Joining and leaving the voice channel has been working, but whenever I attempt to play the song the bot crashes.

Here is the code that I'm executing:

voiceConnections[msg.channel.guild.id].playFile("file.mp3");

where voiceConnections is an object containing VoiceConnection objects mapped to guild IDs, and "file.mp3" is an existing mp3 file.

The bot then crashes with this message:

events.js:141
      throw er; // Unhandled 'error' event
      ^

TypeError: Bad argument
    at TypeError (native)
    at ChildProcess.spawn (internal/child_process.js:274:26)

    at WebSocket.<anonymous> (c:\Users\user\WebstormProjects\pomfbot\node_modules\eris\lib\core\Shard.js:953:34)

I know for sure that the issue isn't finding the file, because if I tell it to play a nonexisting file it crashes with an ENOENT error.

I have all the necessary libs, such as node-gyp, node-opus, and ffmpeg. I have installed Eris without the --no-optional tag. I will be more than happy to provide any additional information.

Thank you for your time,
Ratismal

Seems like Eris is unable to find your ffmpeg or avconv executable, can you double check FFmpeg is working?

[Ratismal]

I'm fairly certain that ffmpeg is working, because I run rhino music bot that uses ffmpeg without issue. Here is the console output for when I run ffmpeg:

Do I need both ffmpeg and avconv installed? The docs have no mention of either.

[davidcole1340]

You only need one installed.

@Ratismal --no-optional installs without optional things like voice

[davidcole1340]

@GusCaplan He said he installed Eris without the tag, it's worded weird, thought that as well.

I have installed Eris without the --no-optional tag.

Sorry for the confusion.
