Audio How to play an audio stream?

Hi,
I need a radio player for my game.
I have an URL and I want to play the audio from it.

I've tried this code:

Code (CSharp):

1. public void Play()
2.     {
3.         StartCoroutine( PlayAudioStrem() );
4.     }
5.     IEnumerator PlayAudioStrem()
6.     {
7.         WWW music = new WWW(URL);
8.         AudioClip clip = music.GetAudioClip(false, true, AudioType.MPEG);
9.         while (!clip || !clip.isReadyToPlay)
10.             yield return new WaitForSeconds(0.1f);
11.      
12.         if (clip)
13.         {
14.             GetComponent<AudioSource>().clip = clip;
15.             GetComponent<AudioSource>().Play();
16.         }
17.     }

The music is playing for several seconds and then stops.

Using Unity2017.
Heard, that WWW is the old class.

I tried UnityWebRequestMultimedia.GetAudioClip(). But I think it works only with files. I can't play the audio stream, only download files.

Please help. What should I use to listen audio stream?

 

this popped up before, I ended up gifting my asset to the dude ;0)
We were able to correct some edge cases with streaming though, at least.
I'll have a look on how UnityWebRequest in 2017 stands, but give me some time plx

 

Also please post the URL you want to stream

 

this one: http://a6.radioheart.ru:8012/live (https works fine too)

about UnityWebRequest.
I tried this way:

Code (CSharp):

1.         UnityWebRequest music = UnityWebRequestMultimedia.GetAudioClip(URL, AudioType.MPEG);
2.         yield return music.SendWebRequest();
3.  
4.         if (music.isNetworkError)
5.         {
6.             Debug.Log(music.error);
7.         }
8.         else
9.         {
10.             AudioClip clip = DownloadHandlerAudioClip.GetContent(music);
11.             Debug.Log( clip + " length: " + clip.length );
12.             if (clip)
13.             {
14.                 GetComponent<AudioSource>().clip = clip;
15.                 GetComponent<AudioSource>().Play();
16.             }
17.         }

And it looped in
yield return music.SendWebRequest();
I think it tries to download entire mp3 or something.

 

yep

overall:
- I think previous WWW.GetAudioClip is completely broken from 5.5. up to 2017.4 I've tested it with
first of all it is necessary to either wait hardcoded time or wait until WWW.progress is reported to be around 0.95 before assigning GetAudioClip clip to an AudioSource
( while progress is updated in 2017.4, but not in 5.4.5. )
- despite having stream flag set I was never able to stream more than few seconds as you mentioned before
- 'yield return www;' does not finish in all cases, so can be forgotten
- asking for audioSource.clip.loadState produced FMOD errors in Console on 5.5.4 - this seemed to be fixed to a degree in 2017.4 at least, though audio still wouldn't play more than few seconds
(I used WWW.GetAudioClip with streaming more or less without problems on 4.x versions, I think starting with 5 cycle is where the changes started to be made)

So the best course of action if you don't want to shelve some monies for a streaming plugin is to constantly bug Unity to implement actual streaming audio handler for UnityWebRequestMultimedia going forward since I think they have no intentions fixing older WWW.GetAudioClip given the state I found it now ;;

 

I see. And what about your asset? Does it work? Could you please test it with my audio stream. I'm thinking about purchasing a plugin for this issue.

 

I don't want to waste money on this for the older version should work fine as well

 

you can download demo from asset store page ( I think I mentioned it before ) and enter url into it
but yes, your url seems to be working with it

 

oh you can try using other libraries, too -
fmod unity intergrations directly (which my plugins uses), NAudio should do it too, and possibly others like bass.net or native libraries for specific platforms

 

Thanks for your answer!
Trying fmod now. Imported fmod.unitypackage to my project.
Do nothing and get BusNotFoundException: FMOD Studio bus not found 'bus:/' on Unity play button.
There is something about fmod studio integration in "getting started". But I need just to play audio stream. Should I install fmod studio and connect fmod project to the Unity somehow?

 

A-a-a-a-a!
It works! (created empty project - and that's it) Great thanks to you, r618!

 

It might be possible to stream from a network location directly in FMOD Studio project, but I've never tried it in fact, I'm using only low level c# wrapper from the integrations (i.e. without fmod studio project)

 

btw they seem to be having a crack at this in 2018.2, from latest beta 2018.2.0b1 release notes:

Scripting: TLS 1.2 support via .Net45 APIs (SslStream, HttpRequest, ...) across all platforms.
Web: Added streamAudio property to DownloadHandlerAudioClip, which lets getting a playable audio clip before download is complete
Audio: Fixed non-readable errors in some cases with streaming audio clips from WWW (764650)
Audio: Fixed streaming an audio clip from WWW directly, without waiting for the download being ready - would throw errors in some cases previously (574945)

Looks like I submitted one of the referenced issues back in 2013, for 4.3.0 (°,,°)

 

For me it doesn't work without an fmod studio project. Will try to figure it out later. Now it works and I'm fine

Wow! It would be great! I'm on 2018.1 now. I'll try when it releases from beta.

 

Please, can someone help to deal with streaming audio. Using Unity to stream audio, i ended up receiving "
Error: Cannot create FMOD::Sound instance for resource 0x*: , (Unsupported file or audio format. )" while trying to receive unfinished audio from download handler. streamAudio property turned to true. Heeeeeeeelp

It might be a bit off-topic, but we did some research about audio streaming recently and released a feature related to audio stream.
It's an interesting solution for capturing in-game audio(server) and playback on other devices(clients) remotely.
Mac/PC/iOS/Android

 

It is not working in iOS build

 

Hey guys, I'm aware that this post is long dead but I make music visualizers and a dj wants me to use it for his live shows. Where do I start to make my project stream the audio output of his computer?

 

this guy does some tutorials on visualizers and has some on using your mic as AudioSource

 

Hi,
Old thread but, where did you enter your live url for Fmod, I'm looking in Fmod Unity asset, nothing, in Fmod studio, nothing...
Any Idea?
Thanks

 

Hi ,
It might be late but can help other devs searching for similar functionality for iOS and Android. I have used following plugins to stream audios from web servers without downloading. The audio visualizer asset for android is also very helpful. Developer is helpful too. Links :
iOS : https://assetstore.unity.com/packages/tools/audio/audio-stream-in-ios-182585
Android : https://assetstore.unity.com/packages/tools/integration/audio-stream-in-android-196464
Android Visualizer : https://assetstore.unity.com/packages/tools/integration/audio-visualizer-for-android-38377

 

Years later and streaming still doesn't work haha.

it seems that the AudioClip created by the UnityWebRequest still doesn't respect the streaming load type.

 

Ha yeah, here's my solution using NAudio

Great! but I don't wanna embed another plugin

Plus the license doesn't work for me as I need it for commercial applications
