audio - Fetching MP3-Tags while recording a stream using java -
i have code, records (mp3-)stream:
public class recorder { private static final int buffer_size = 2048; private thread thread; private boolean running = false; public recorder(url stream, file dest) { thread = new thread(() -> { try { urlconnection connection = stream.openconnection(); inputstream instream = connection.getinputstream(); outputstream outstream = new fileoutputstream(dest); byte[] buffer = new byte[buffer_size]; int length; system.out.println("now recording " + stream.tostring()); while ((length = instream.read(buffer)) > 0 && running) { outstream.write(buffer, 0, length); } outstream.close(); } catch (ioexception e) { e.printstacktrace(); } }); } public void start() { running = true; thread.start(); } public void stop() { running = false; try { thread.join(); } catch (interruptedexception e) { e.printstacktrace(); } } } how read mp3-tags (song title , artist name) stream properly? i've found few answers on how fetch mp3-tags files, not streaming audio.
thanks.
you can use mp3agic library.
a java library reading mp3 files , reading / manipulating id3 tags (id3v1 , id3v2.2 through id3v2.4).
if file has id3 tags can do:
mp3file mp3file = new mp3file("src/test/resources/v1andv23tagswithalbumimage.mp3"); if (mp3file.hasid3v1tag()) { id3v1 id3v1tag = mp3file.getid3v1tag(); system.out.println("track: " + id3v1tag.gettrack()); system.out.println("artist: " + id3v1tag.getartist()); system.out.println("title: " + id3v1tag.gettitle()); system.out.println("album: " + id3v1tag.getalbum()); system.out.println("year: " + id3v1tag.getyear()); system.out.println("genre: " + id3v1tag.getgenre() + " (" + id3v1tag.getgenredescription() + ")"); system.out.println("comment: " + id3v1tag.getcomment()); }
