Error parsing ffmpeg stats: strconv.ParseFloat: parsing "N": invalid syntax

[IoIxD]

The error in the title clogs the terminal as the library struggles to play the first few seconds of any audio file without stuttering, and it eventually just outright changes to Voice connection closed, then inevitably timeout waiting for voice, then inevitably it panics with invalid memory address or nil pointer dereference.

A video of the error can be seen here

My code is as follows:

// start the audio session
options := dca.StdEncodeOptions
encodingSession, r := dca.EncodeFile("HOTEL_MARIO_TONE.mp3", options)
er(r)
defer encodingSession.Cleanup()

done := make(chan error)
dca.NewStream(encodingSession, vc, done)
err = <- done
if(err != nil && err != io.EOF) {
	// keep trucking, actually.
	fmt.Println(err)
}

My ffmpeg version is 5.1, however this happened on 5.0 as well. I don't think the audio file is important because this error persists across three of them, but here it is (note that the fact that it's one second long doesn't matter, it does this with many other longer fiels as mentioned previously)

Got the same problems, but it doesn't seem to stop the stream, still work fine

The same problem. Can't covert file. The same error

Getting the same error when encoding to .dca. I think it has something to do with the ffmpeg args from the encode.go file. Maybe fffmpeg syntax has changed since this was released?
I will try it with an older version of ffmpeg from around six years ago: https://ffmpeg.org/releases/

Edit:It has something to do with (at the very least) how the speed stat is read from FFMPEG. It expects a float but get "N/A" instead. I think thats where the "N" in the error comes from.

Similar problem, but in a slightly different place: unrecognized -vol flag. For this I had to vend this package, comment out this flag in this line, and specify "volume=1.0" value in the AudioFilter field of the EncodeOptions.
