Question Download OGG in WebGL get Length and play?

I don understand why there is a probjem with downloading OGG files using webrequests in WebGL?

If i use appropriate OGGVORBIS format then I get "Streaming of 'ogg' on this platform is not supported" error. Though Unity itself converts audio to Vorbis for WebGL builds.

And the second problem is even if Im able to download and play ogg via AUDIOQUEUE type or mp3 - I always get Length 0, and I need it for a slider.

Is there any proper way to download ogg, get its length and play in WebGL builds?

 

So, I managet to make it work for now. Here is the code. The secret ingredient was to await till audio_clip's loadState is Loaded after download web request is complete. Now I get Length, though Frequency and samples are differ from real files parameters. And I still need to use AUDIOQUEUE as file type to download OGG.

Code (CSharp):

1. var audio_download_handler = new DownloadHandlerAudioClip(string.Empty, audio_type)
2.             {
3.                 streamAudio = is_stream_audio,
4.                 compressed = is_compressed_audio
5.             };
6.          
7.             using var file_request = new UnityWebRequest(url, "GET")
8.             {
9.                 downloadHandler = audio_download_handler
10.             };
11.  
12.             try
13.             {
14.                 using var audio_download = await file_request.SendWebRequest();
15.  
16.                 var audio_clip = audio_download_handler.audioClip;
17.              
18.              
19.              
20.                 if (audio_clip != null) audio_clip.name = Path.GetFileName(url);
21.  
22.                 await UniTask.WaitUntil(() => audio_clip.loadState == AudioDataLoadState.Loaded);
23.              
24.                 return audio_clip;
25.             }

And yes, its indeed AAC Unity converts to, my bad. But this case proves that WebGL CAN download and play OGG files. I dont need streaming play, only download and then play. Hope this can be implemented cleanely some day.
