Android Question ExoPlayer-ID3 metadata how to get data

kisoft · Dec 30, 2019

Hi
This is a continuation of this thread:
https://www.b4x.com/android/forum/threads/exoplayer-id3-metadata.112430/
This is the code that Erel put:

B4X:

Sub Player_TrackChanged
   Dim jo As JavaObject = player1
   Dim TrackGroups As JavaObject = jo.GetFieldJO("player").RunMethod("getCurrentTrackGroups", Null)
   For i = 0 To TrackGroups.GetField("length") - 1
       Dim TrackGroup As JavaObject = TrackGroups.RunMethod("get", Array(i))
       For j = 0 To TrackGroup.GetField("length") - 1
           Dim Format As JavaObject = TrackGroup.RunMethodJO("getFormat", Array(j))
           Dim Metadata As JavaObject = Format.GetField("metadata")
           If Metadata.IsInitialized Then
               Log("Found: " & Metadata)
           End If
       Next
   Next
End Sub

How to dive deeper to get the information you need? It seems that the information you need is in these classes. How to get them.?

What is the output of this code?

Please use [CODE]code here...[/CODE] tags when posting code.

@DonManfred Yeah, I did, but some mistake jumped out the first time.

Erel · Jan 1, 2020

I see that you extracted information from the data. What exactly are you missing?

kisoft · Jan 1, 2020

Hello, happy new year for all of us.
I was able to enter the IcyHeaders class and get the stream name from useful things. I would still like to get the artist name, song name, album cover picture and so on.
This information can be found in other classes. I just don't know how to get into them.

Metadata.Entry (ExoPlayer library)

Erel · Jan 1, 2020

Add this code and post the output:

B4X:

'after If metadata.IsInitialized
For k = 0 To metadata.RunMethod("length", Null) - 1
Dim Entry As JavaObject = metadata.RunMethod("get", Array(k))
Log("Entry: " & Entry)
Log(GetType(Entry))
Next

kisoft · Jan 1, 2020

I get an error: an unknown user get. I have to join some library?

Erel · Jan 1, 2020

I've updated the above code. It should be RunMethod.

kisoft · Jan 1, 2020

Entry: (IcyHeaders) IcyHeaders: name="[RMF LADY PANK]", genre="RMF LADY PANK", bitrate=128000000, metadataInterval=1024
com.google.android.exoplayer2.metadata.icy.IcyHeaders
resources in this class:

B4X:

IcyHeaders(int bitrate, String genre, String name, String url, boolean isPublic, int metadataInterval)

I can now download them with this code

B4X:

Dim jo As JavaObject= Metadata.RunMethod("get", Array(0))
                Log ("log2="&jo)
          
                Dim mime As String = jo.GetField("url")
                Log("url: "&mime)
              
                mime=jo.GetField("name")
                Log("name: "&mime)

Erel · Jan 1, 2020

This is the only information available in this case.

kisoft · Jan 1, 2020

Okay, I'll try with the other streams.
Thank you for your time.

kisoft · Jan 1, 2020

I tested for many streams and unfortunately the effect is the same every time.

I am also interested in reading the artist name and song title for radiostreams with Exoplayer. So far I use AAC Player which works very well but unfortunately seems no longer supported and does crash after using it for a while. See: https://www.b4x.com/android/forum/t...io-aac-decoder-for-android.59567/#post-498602
Can you post the streams and the entire B4A code so I can take a look?

exo player can do it with plugin ..

I hope we can solve this problem, or I'll lose my contract. (customer order)

kisoft · Jan 7, 2020

Fortunately, most of the streams it uses do not contain this data anyway. That's why this code is enough here. For the rest I download via Okhttp and update manually (unfortunately this requires using a timer to refresh and treat each station separately).

P.S. On Android, every failure can be picked up. Connect in USB mode...

It's not to difficult, I created a php script that retrieves the meta data. I can share the php code if you need it.
see the result for NPO SterrenNL

B4X:

.
.
.
    url = $"http://ice.pdeg.nl/getIcy.php?url=${Starter.selectedStream}"$
    job.Initialize("", Me)
    job.Download(url)
    job.GetRequest.Timeout = Starter.jobTimeOut
    Wait For (job) JobDone(job As HttpJob)
        
        
    If job.Success Then
        nSong = job.GetString
        job.Release
.

@PdeG If you can share the code, share it. Many people will be happy to benefit.
