iOS Question MediaPlayer doesn't play mp3 files

[stephane..blusson]

Hi, I am developing a chat with audio messaging and I faced a problem. I can download the file from the server using FTP, but I cannot play it, I have the error here:

Mp.Initialize(File.DirDocuments, audiomessagefilename, "MP")

Error:
Error loading file: Error Domain=NSOSStatusErrorDomain Code=1685348671 "(null)"

P.S. I can see the file in the directory using this code

        For i = 0 To File.ListFiles(shared).Size - 1
            Log(File.ListFiles(shared).Get(i))
        Next

maybe someone came across this problem and can help me

MediaPlayer is able to play mp3. Did you try to recreate it in iTunes ? https://support.apple.com/ru-ru/guide/itunes/itns2972/windows

Thanks for the answer

This looks like a pretty good solution. But the problem is that audio messages are stored on the server, where they can be sent from an android device and there will be no possibility to edit the audio. Maybe mediaplayer isn't the only solution to this problem?

Doubt in success, but you can try AVPlayer, which allows to play URL.

Declare global variable

Private player1 As NativeObject

Add, for example, to Application_Start

    player1 = CreatePlayer("https://<path>.mp3")
    player1.RunMethod("play", Null)

In addition add Erel's subroutine

Sub CreatePlayer(url As String) As NativeObject
   Dim u As NativeObject
   u = u.Initialize("NSURL").RunMethod("URLWithString:", Array(url))
   Dim player As NativeObject
   player = player.Initialize("AVPlayer").RunMethod("alloc", Null).RunMethod("initWithURL:", Array(u))
   Return player
End Sub

The problem is somewhere else. Maybe the file isn't downloaded properly.

Thanks for the answer. I decided to test your assumption
I uninstalled the application and tried to download these files again via FTP. The download was successful (Success = True in FTP_DownloadCompleted).
Displayed the size of this file in the audio playback function

Log(File.Size(shared, "!AudioMsg-1633353000129.mp3"))

and it is 3672

Is that the correct size? Looks a bit small.

Thanks for the advice. I downloaded a file from the server with a size of 62451. I thought there might be a problem with the file name, because it starts with a "!" But the error has not gone anywhere. I tried to upload the file directly to the server and then download it and play it on Ipad and everything worked, but my audio messages from android break on the initialization of the Media Player.

P.S. I tried to download the file from the server to the pc and it plays without problems

I probably fixed this problem using extensions .WAV
