Please check first if your issue haven't already been reported yet.

Editor crashes upon trying to use a song that contains metadata (i.e, artist metada).
(actual crash error)

Recreation Steps

• Use a audio file that contains metadata for an artist (easiest way for this is to get a song from cobalt.tools from youtube, andthen use it after converting it via ffmpeg to ogg)
• Add it into the editor, whether voices or instrumental track, the following should be result:
  
  The intended result should be the following:
  
• After this, create the song as normal and proceed to try to edit the diffculty.
• The game should return an error, and then crash.

this is so stupid lmao

ok I LIEEED this seems to be after encoding with ffmpeg from any file to an ogg
use the following command or whatever to tes tthis out should be obvious what song path is
ffmpeg -i "songPath\song.mp3" -c:a libopus -b:a 128k "songPath\song.ogg"

wait can you pass me the audio
this is so odd😭

[tivvo]

ignore that its subterfuge its the quickest thing i could think of that i can reencode for this
evilterfuge.ogg.zip
also yeah just tested on mac using whisky doesn't wanna work either

[NexIsDumb]

aight, i'll check later on then

I am absolutely confused how implementing an artist into the OGG metadata even causes a Null Object Reference like this. Like, is there just something wrong with how the current audio system implements audio metadata or something that causes it to return a nonexistent object??

iirc, even when stripping the metadata still caused an issue, although i do have a theory that the bitrate is too high for the song (it being 128k/b), i'll try a 32k/b encode instead and see if the same thing comes up

wonder if this is a haxel issue also

[tivvo]

bad news

(still fucks up with a lower bitrate)

[r6915ee]

I'm guessing that based on the images it's probably somewhere within the audio player.

Does this issue happen with the voices as well?

[tivvo]

yep, seems that from the actual crashing error the waveform that generates does not like it at all
possible solution could be to catch a waveform error and instead not generate it and let the editor just work like normal
(or don't and fix the issue, first thing could save alot of stress though imo)

[r6915ee]

My only guess right now is that it searches for the audio data at a very specific location in the file, but the metadata is in place of that and it crashes. I'm not sure if that is correct, I've never delved into how Ogg Vorbis works, I've never delved into how the waveform is generated, I've never delved into how ffmpeg converts into Ogg, but that's really what I've got so far.

You seem to have encoded it using Opus rather than Vorbis here.
I don't think that Flixel natively supports Opus so you need to encode it with Vorbis instead.
Command: ffmpeg -i "songPath\song.mp3" -c:a libvorbis -b:a 128k "songPath\song.ogg"
