जावा ध्वनि एपीआई का उपयोग कर एमपी 3 बजाना

क्या आप कृपया सुझाव दे सकते हैं कि मैं एक टुकड़ा कैसे लिख सकता हूं जो एक गाना खेलता है।

मैंने निम्नलिखित स्निपेट की कोशिश की लेकिन मुझे यह अपवाद मिलता है: यहां छवि विवरण दर्ज करें

import sun.audio.*; import java.io.*; class tester { public static void main(String args[]) throws Exception { InputStream in=new FileInputStream("tester.mp3"); AudioStream as=new AudioStream(in); AudioPlayer.player.start(as); } } 

वेब के समाधान से एकत्रित समाधान "जावा ध्वनि एपीआई का उपयोग कर एमपी 3 बजाना"

जैसा कि उल्लेखित है, जावा ध्वनि डिफ़ॉल्ट रूप से एमपी 3 का समर्थन नहीं करता है किसी भी विशिष्ट AudioSystem.getAudioFileTypes() में इसका समर्थन करने वाले प्रकारों के लिए, AudioSystem.getAudioFileTypes() जांच करें।

एमपी 3 पढ़ने के लिए समर्थन जोड़ने का एक तरीका जेएमएफ आधारित एमपी 3 प्लगिन.जर 1 को एप्लिकेशन के रन-टाइम क्लास-पथ में जोड़ना है।

आपके वास्तविक प्रश्न के मुताबिक , जब एक javax.sound.sampled.Clip इस प्रकार के कार्य के लिए आदर्श लग सकता है, दुर्भाग्य से केवल एक स्टीरियो, 16 बिट, 44.1 केएचएचज़ ध्वनि का एक दूसरा होगा। यही कारण है कि मैं BigClip विकसित की (जिसकी लूपिंग के साथ अपनी समस्याएं हैं, अगर आप उन्हें ठीक कर लेते हैं, तो वापस रिपोर्ट करें।)

सन साउंड एपीआई एमपी 3 को नहीं खेलती है

जब मुझे इसकी आवश्यकता है, मैं जावाज़ोम जेलेयर लाइब्रेरी (http://www.javazoom.net/javalayer/javalayer.html) का उपयोग करता हूं।

एमपी 3 को चलाने में सक्षम होने के लिए आपको अभी भी एमपी 3 एसपीआई (जेएलयर के साथ उपलब्ध कराई गई) जोड़नी होगी।

मैंने बिगक्लिप कोड के साथ आने वाली बगों के आधार पर एक संपादन करने का प्रयास किया, हालांकि इसे अस्वीकार कर दिया गया था। निम्न कोड कार्यक्रम के लिए मेरे फिक्स हैं। ध्यान रखें कि इनमें से कुछ अभी भी निहित नहीं है क्योंकि मैं वास्तव में पाशन, तेज़-अग्रेषण या रिवाइंडिंग से वास्तव में चिंतित नहीं था।

संपादित करें: परीक्षण और अद्यतन कोड चलाएं क्योंकि यह रिवाइंड / फास्ट फॉरवर्ड के साथ काम नहीं कर रहा था। अब यह काम करता है, लेकिन फिर भी looping का परीक्षण नहीं हुआ है, हालांकि इसे सैद्धांतिक रूप से काम करना चाहिए।

यहां बिग्लिप कोड अपडेट करें: http://pastie.org/4523763

Media.io की ऑनलाइन सेवा का उपयोग कर .wav को फ़ाइल में कनवर्ट करें; तो अपने कार्यक्रम में इसका इस्तेमाल करें।

  String file="SOME//SONGFILE//PATH"; FileInputStream fis = new FileInputStream(file); BufferedInputStream bis = new BufferedInputStream(fis); player = new Player(bis); player.play(); 

जार फ़ोल्डर्स आपके पास होनी चाहिए: mp3plugin.jar और jlayer.jar (google करें)

मुझे विश्वास नहीं है कि जावा ऑडियोस्ट्रीम क्लास एमपी 3 को मूल रूप से समर्थन करता है। इस लिंक के अनुसार यह केवल एआईएफएफ, एयू और डब्लूएवी का समर्थन करता है। आपको एक एमपी 3 फाइल लोड करने और चलाने के लिए एक अन्य पुस्तकालय का उपयोग करना होगा।

यह साइट बताती है कि जावा में एक एमपी 3 फाइल कैसे खेलेंगी
