Hi all, I'm trying to add the functionality to my music bot to allow it to play files uploaded to the guild. I've got it playing everything with createAudioResource, but the returned resource object doesn't contain the length of the audio resource. How might I get this information without downloading the file separately? Many thanks.

Documentation suggestion for @hardy elm:
property AudioResource#playbackDuration
The playback duration of this audio resource, given in milliseconds.

does that not work?

#

that's the current duration, not total

#

or at least that what it looks like, given how it gets incremented during each read()

native quail does that not work?

Yes, that's the elapsed time, not total length

My guess is that because AudioResource could be a stream, it doesn't provide a total length. Think I'm going to have to do some header decoding

use ffmpeg @hardy elm

Not sure how ffprobe will deal with incomplete files

#

I already know the offsets in the WAV file header, and FLAC isn't too hard either

#

there's already an npm module for estimating mp3 lengths

#

well there is a way using ff probe
