-----------------------------------------------------
DESCRIPTION :
-----------
JLayer is a library that decodes/plays/converts MPEG 1/2/2.5 Layer 1/2/3
(i.e. MP3) in real time for the JAVA(tm) platform. This is a non-commercial project
and anyone can add his contribution. JLayer is licensed under LGPL (see LICENSE.txt).
FAQ :
---
- How to install JLayer ?
Before running JLayer you must set PATH and CLASSPATH for JAVA
and you must add jl1.0.1.jar to the CLASSPATH.
- Do I need JMF to run JLayer player ?
No, JMF is not required. You just need a JVM JavaSound 1.0 compliant.
(i.e. JVM1.3 or higher).
- How to run the MP3TOWAV converter ?
java javazoom.jl.converter.jlc -v -p output.wav yourfile.mp3
(Note : MP3TOWAV converter should work under jdk1.1.x or higher)
- How to run the simple MP3 player ?
java javazoom.jl.player.jlp localfile.mp3
or
java javazoom.jl.player.jlp -url http://www.aserver.com/remotefile.mp3
Note : MP3 simple player only works under JVM that supports JavaSound 1.0 (i.e JDK1.3.x+)
- How to run the advanced (threaded) MP3 player ?
java javazoom.jl.player.advanced.jlap localfile.mp3
- Does simple MP3 player support streaming ?
Yes, use the following command to play music from stream :
java javazoom.jl.player.jlp -url http://www.shoutcastserver.com:8000
(If JLayer returns without playing SHOUTcast stream then it might mean
that the server expect a winamp like "User-Agent" in HTTP request).
- Does JLayer support MPEG 2.5 ?
Yes, it works fine for all files generated with LAME.
- Does JLayer support VBR ?
Yes, It supports VBRI and XING VBR header too.
- How to get ID3v1 or ID3v2 tags from JLayer API ?
The API provides a getRawID3v2() method to get an InputStream on ID3v2 frames.
- How to skip frames to have a seek feature ?
See javazoom.jl.player.advanced.jlap source to learn how to skip frames.
- How much memory/CPU JLayer needs to run ?
Here are our benchmark notes :
- Heap use range : 1380KB to 1900KB - 370 classes loaded.
- Footprint : ~8MB under WinNT4/Win2K + J2SE 1.3 (Hotspot).
~10MB under WinNT4/Win2K + J2SE 1.4.1 (Hotspot).
- CPU usage : ~12% under PIII 800Mhz/WinNT4+J2SE 1.3 (Hotspot).
~8% under PIII 1Ghz/Win2K+J2SE 1.3.1 (Hotspot).
~12% under PIII 1Ghz/Win2K+J2SE 1.4.1 (Hotspot).
~1% under PIII 1Ghz/Win2K+J2SE 1.5.0 (Hotspot).

KNOWN PROBLEMS :
--------------
99% of MP3 plays well with JLayer but some (1%) return an ArrayIndexOutOfBoundsException
while playing. It might come from invalid audio frames.
Workaround : Just try/catch ArrayIndexOutOfBoundsException in your code to skip
non-detected invalid frames.
