Internet/Radio-Stream wiedergeben

[Tommy1988]

Hallo, wie kann ich, wenn ich eine URL habe, einen Stream den ich zuvor in ein Edit-Feld
eingegeben habe mit einer Delphi-Anwendung wiedergeben?

Wohl mit Bass und dem allen oder ?
Leider verstehe ich das nicht, kann mir wer ein Beispiel zeigen?

ist das hier vielleicht schon soetwas?

Delphi-Quellcode:

var   

    URL_SaveFile    :  String;
    URL_FileStream  :   TFileStream;


procedure DownloadProc(buffer: Pointer; length: DWORD; user: DWORD); stdcall;
begin
  with AudioPlayer do
   begin
  if (URL_SaveFile = '') then
    exit;

  if (URL_FileStream = nil) then
      URL_FileStream:= TFileStream.Create(URL_SaveFile, fmCreate); // create the file
  if (buffer = nil) then
      URL_FileStream.Free // finished downloading
   else
      URL_FileStream.Write(buffer^, length);
end; 
end;


function TAudioEngine.PlayURL(URL : String) : boolean;
var SngLen : Integer;  Flags  : DWORD;
begin
    Cur_FileName:= URL;
    BASS_MusicFree(Channel);
    BASS_StreamFree(Channel);
    URL_FileStream:= nil;

     Flags:= 0;
   if StrBlock then
      Flags:= BASS_STREAM_BLOCK;

    { (BASS_STREAM_BLOCK) Download and play the file in smaller chunks.
      Uses a lot less memory than otherwise,
      but it's not possible to seek or loop the stream - once it's ended,
      the file must be opened again to play it again.
      This flag will automatically be applied when the file length is unknown,
      for example with Shout/Icecast streams.
      This flag also has the effect of resticting the download rate.}

    Flags:= Flags or BASS_STREAM_META or BASS_STREAM_STATUS;

    Channel := THandle(BASS_StreamCreateURL(PChar(Cur_FileName), 0, Flags,  @DOWNLOADPROC, 0));

    SngLen := 0;

   if (Channel = 0) then
       Result := False
    else
       Result := True;

   if not BASS_ChannelPlay(Channel, false) then
       Result := False;

   if (SngLen = 0) then
       SongLength := BASS_StreamGetLength(Channel);

    PlayerState := ENGINE_PLAY;
end;

wo denn da ? ich blicke auf der webseite überhaupt nicht durch

Edit: ok habs gefunden.

aber wie mach ich das denn jetzt so, dass ich ein URL in ein Edit eintragen kann, dass dieser sttream dann gespielt wird.. habs schon hin und her probiert, nur da verlässt mich die fantasie

[Gehstock]

Delphi-Quellcode:

procedure TForm1.Button12Click(Sender: TObject);
var
  ThreadId: Cardinal;
begin
  StrPCopy(proxy,ed_ProxyServer.Text);
  if (cthread <> 0) then
    MessageBeep(0)
  else
    cthread := BeginThread(nil, 0, @OpenURL, PChar(Edit1.text), 0, ThreadId);//oder sonst ein editfeld
end;

is zwar uralt das thema aber mich würde intressieren wie ich einen stream mit portangabe laufen lassen kann ?

bsp.:

IP:8000\listen.pls

vll bekomm ich ja noch eine antwort

edit:

habe mich etwas umgeschaut, in der listen.pls steht ja die ip + port

also funktioniert das ja auch
dann hab ich doch nochma geschaut un in der bass.dll steht als fehlercode 41 das dass dateiformat falsch sei

im beispiel steht ja :
http://somafm.com/secretagent24.pls

in dieser datei dies :

[playlist]
numberofentries=1
File1=http://voxsc1.somafm.com:8082
Title1=SomaFM: Secret Agent (#1 24k mp3): The soundtrack for your stylish, mysterious, dangerous life. For Spies and PIs too!
Length1=-1
Version=2

öffne ich nun die zustreamende datei steht folgendes :
[playlist]
numberofentries=1
File1=http://95.208.31.166:8000

nur immer wieder sagt er mir fehlercode 41

kann doch nicht sein oder ?
