Hallo,
Ich bastel zur Zeit an einem Shoutcast – Streamripper und werde bald wahnsinnig
Mein Problem ist es das ich nicht ganz genau weis wie ich die Mp3 richtig zusammensetze.
Als Hilfe habe ich folgende Seite genutzt:
www.smackfu.com/stuff/programming/shoutcast.html
Statt den normalen Sound höre ich nur etwa 1-2 Sekunden haken und dann stoppt die Wiedergabe.
Vielleicht hat einer von euch ja bereits ähnliches getan und könnte mal über meinen (Anfänger)-Code gucken

Wäre für jeden Tip riesig dankbar.
Bin mir auch nciht ganz sicher ob ich an der richtigen Stelle anfange die MP3-DatenBytes zu zählen ... brauch dringend Hilfe
danke schonmal  |
