I have tried many times trying to get ogg support in Java but have been unsuccessful.
I have tried using Jorbis and another method for implementing ogg playback in Java but cannot seem to do so.
Can someone point me in the right direction on implementing ogg in java?
3D sound system is the best I've tried(It just works) and can be used not just in JPCT: http://www.jpct.net/forum2/index.php/topic,1057.0.html
Check out FFsampledSP. It's a free, FFmpeg-based implementation for Win and OSX that implements the javax.sound.sampled interfaces.

I am using JLayer sound framework to play wav files with basic functionality (seek,play/pause/stop), I need now to also allow playback speed changes.
Does anyone know if JLayer allows this functionality (I have looked everywhere and I cant find it), and how do I implement it?
If JLayer does not support it how can I implement this?
Can anyone direct me to any source code, documentation or the theoretical aspects behind changing the playback speed?
I want to code an audio player in Java. java.JavaFX has a very nice support for mp3 playing but I want in my player also the possibility to listen to radio.
The problem is I have searched for some time and I didn't find something that works like I want:
MP3SPI - this is nice but just wont
play some streams
vlcj - I've tested the latest version
1.2.0 but was with a beta version of VLC so I had times when the stream
just stopped for no reason.
NativeSwing's windows media player
but that is a heavyweight component
and also I don't want to make it
dependable on WMP.
So I'm kind of out of luck. Well guys If you know more about this topic please share it!
Thank you!
MP3 playback in Java is a bitch. In nearly any case it's not worth the work you put in it.
However, this is something that worked for me. It can easily be recoded to play Shoutcast streams.
JavaLayer (library behind MP3SPI) is a mature project and should handle most streams, can you post some streams that it can not read? Check that other players using JavaLayer, like jlGUI, can play these streams. Maybe it's something with your code.
How can I get video and audio streams from web cameras with Java (in a cross-platform way)?
For example, we have a computer with 3-4 USB web cameras; we want to get their streams and make them visible in the user interface. How can we perform such a thing? I need code for a simple app which would find ALL cameras on the computer and let us select camera to wach. Can any one, please share such one?
With java media framework JMF or FMJ
Here is an example with JVM
I see your comment about the solution needing to be "pure" java, but this is really "nearly" impossible. You will need to use some sort of native library for accessing the devices, with that being stated; I suggest that you look at Xuggler as your solution. Xuggler supports Windows, Mac, and Linux and they also offer example code for handling audio and video. Lastly the library is FREE.
Webcam capture example: http://xuggle.googlecode.com/svn/trunk/java/xuggle-xuggler/src/com/xuggle/xuggler/demos/DisplayWebcamVideo.java
While Xuggle does not have an example of microphone capture, you can find samples on the mailing list or you could use code written by the packet-mulitbroadcaster project found here: https://code.google.com/p/packet-multibroadcaster/
You can try my solution. It uses OpenCV to capture the image and jetty server to transmit it via WebSocket. The example has three classes and it will be easy to understand.
Now I can send only video, but I'm working on audio aswell.
I'd use flex. It can be relatively easily integrated with java backend.
UPD:
Pure Java needed
Then you should consider JavaFX solutions. I'm not a big expert in javafx, I've only written some basic test applications, but I'm sure it's a modern way of solving described problem with pure java.
I need simple video playback in Java.
Here are my requirements:
PRODUCTION QUALITY
Open and decode video files whose video and audio codecs can be chosen by me. I.E I can pick well behaving codecs.
Be able to play, pause, seekToFrame OR seekToTime and stop playback. Essentially I wish to be able to play segments of a single video file in a non linear fashion. For example I may want to play the segment 20.3sec to 25.6sec, pause for 10 seconds and then play the segment 340.3sec to 350.5sec, etc.
During playback, video and audio must be in sync.
The video must be displayed in a Swing JComponent.
Must be able to use in a commercial product without having to be open source (I.E. LGPL or Comercial is good)
My research has led me to the following solutions:
Use Java Media Framework + Fobs4JMF
http://fobs.sourceforge.net/f4jmf_first.html
I have implemented a quick prototype and this seems to do what I need. I can play a segment of video using:
player.setStopTime(new Time(end));
player.setMediaTime(new Time(start));
player.start();
While Fobs4JMF seems to work, I feel the quality of the code is poor and the project is no longer active. Does anyone know of any products which use Fobs4JMF?
Write a Flash application which plays a video and use JFlashPlayer to bring it into my Java Swing application
Unlike Java, Flash is brilliant at playing video. I could write a small Flash application with the methods:
open(String videoFile),
play(),
pause(),
seek(int duration),
stop()
Then bring it into Java using JFlashPlayer which can call Flash functions from Java.
What I like about this solution is that video playback in Flash should be rock solid. Has anyone used JFlashPlayer to play video in Java?
Write a simple media player on top of Xuggler
Xuggler is an FFMpeg wrapper for Java which seems to be a quite active and high quality project. However, implementing the simple video playback described in the requirements is not trivial (Seeking in particular) but some of the work has been done in the MediaTools MediaViewer which would be the base upon which to build from.
Use FMJ
I have tried to get FMJ to work but have had no sucess so far.
I would appreciate your opinions on my problem.
Can a brother get a shout out for Xuggler?
In my mind, VLCJ is the way forward for this type of thing. I love Xuggler for encoding / transcoding work, but unfortunately it's just so complicated to do simple playback and solve all the sync issues and suchlike - and it does very much feel like reinventing the wheel doing so.
The only thing with VLCJ is that to get it to work reliably with multiple players I've had to resort to out of process players. The framework wasn't the simplest thing in the world to get in place, but when it's there it works beautifully. I'm currently running 3 out of process players in my app side by side with no problems whatsoever.
The other caveat is that the embedded media player won't work with a swing component, just a heavyweight canvas - but that hasn't proven a problem for me at all. If it does, then you can use the direct media player to get a bufferedimage and display that on whatever you choose, but it will eat into your CPU a bit more (though no more than other players that take this approach.)
JavaFX has a number of working video and audio codecs builtin. It's likely to be the solution with the broadest support at the moment.
I've been using jffmpeg in the same way you use FOBS, it works pretty well, although I haven't compared them.
I would also love to see an easy way to interface with native codecs the way that JavaFX does, but there doesn't seem to be real integration between JavaFX and Java.
There has also been some work trying to get the VLC library libvlc into java. I haven't tried it yet and would be interested to hear back from anyone who has.
haven't tried Xuggler (which i'm interested in) but I'm having a good time with VLCJ. The drawback I find in it is only that you have to have VLC installed prior to your application.
I'd recommend using MPV. You can use it in combination with JavaFX quite easily, see this example.
In short, you use a little JNA magic to use the MPV native libaries directly, and then let the video display on a JavaFX stage. If you use a child stage, you can even overlay JavaFX controls on top of the video (with full transparancy support).
VLC (with VLCJ) can be used in a similar fashion, but I find that the MPV solution performs better (faster seek and start times).
I have a list of radio stations, mostly .mp3 and .ogg. I would like to have a player on a web page that could be controlled with JavaScript. Now I use jlgui, but it is somewhat limited.
Do you know of any alternative to jlgui? Preferably a java applet, but I can tolerate flash or even a system-default media player for a particular content-type.
There are a thousand MP3 players for Flash, using the native streaming stuff. Unfortunately that copes generally poorly with streamed MP3 (either over Icecast HTTP, or even more so under SHOUTcast ICY). Generally the player has to reconnect to the stream every so often, causing a playback glitch, otherwise memory just fills with MP3 data.
OGG is harder. There's no native support, but in Flash 10 you can play any old samples you can decode yourself, so it's possible to implement your own OGG decoder. It needs a lot of CPU on the client though. See http://barelyfocused.net/blog/2008/10/03/flash-vorbis-player/ — I don't know of anyone having fixed this up into a single player that can do both MP3 and OGG from the same interface yet, but there's no reason it shouldn't be possible.
I found JPlayer which uses HTML5 if available, otherwise it falls back to Flash. Works almost as good as the JLgui
You can use the JMF I guess:
