Rtp to wav(or au, etc) with JMF?

these days i'm working on a program with JMF, it's sth like an ip phone sniffer, it sends arp spoof packets to ensure all the audio/video streams to pass through the sniffer in a switched lan, and the sniffer captures these streams and plays these streams, my question is:how can i save these rtp streams to a wav(or au, etc) file while playing them, or just save the rtp packets into a file like ethereal capture file, and use JMF API to play the captured file?
sorry for my english, thanks a lot.

Hi
I also have project to convert the rtp packet captured by jpcap (payload: G.711 pcmu,from voip) in to wav file
Did you find the solution? And if so , could you tell me how to do this or send me the source code please?
My e-mail:[email protected]
I really need it
Thank you,
Best regards

Compressing the wav file with JMF

Hi Guys,
Any one of you know about how to compress a wav file with jmf.Please its very urgent.
Thnaks
Jast

Specify a compressed encoding for the audio output format. You'll have to enumerated the supported formats on the output track to finds out what's available to you. In Windows, JMF should be able to use the available system codecs. First try transcoding a wave file in JMStudio to see what works.

RTP (UDP) multicast stream with JMF...?!

Hi.
I am quiet new in the material of jmf and its plugins. I have a network which offers me an UDP stream (mpeg2 or mpeg4 both could be available). I can watch this stream with an freewareplayer called VLC.
When using the JMF Studio tool, I can't watch the stream ... The Player is waiting for signals and breaks after 60 seconds. So, okay ... Maybe the JMF doesn't bring the right codec with it.
Now I've installed jffmpeg, but that doesn't help a lot. I write done the JAR File in Classpath and installed the Plugin, MimeType and Demultiplexer (as described) in the JMF Registry. The behaviour of JMF Studio is the same. Does anybody have an idea wether jffmpeg supports this kind of streaming
and/or what I can do to get the stream?! Maybe there is an better Plugin for my solution.
I can't suppose that nobody here ever tried to get an Mpeg2 or Mpeg4 multicast stream with JMF. There must be an solution.
Many thanks for your help and reply!

Hi funnyjanni,
May be I am writing this after 4 years.
I am also in the stage when you faced the same problem. You might have found the solution to this.
Please help me on this. I am trying to use jffmpeg to play UDP mutlicast stream.

Play sdp file with JMF

Hi,
I have a Darwin Streaming Server(DSS) running on a machine, that reflects several broadcasts from other machines (I'm broadcasting to the DSS with JMF).
I can see all the videos and audio without any problem with Quick Time, but I can't find a way to play the sdp files with jmf. I've searched the web for jmf and sdp, and there isn't much information, i've also tried to play with JMStudio..no luck. In the JMF solution there aren't any samples for SDP files....
If I can't find a way to do it, I'll use Quick Qime 4 Java, the only problem is that there isn't a linux implementation :(
Thanks in advance.
Best regards,
ANeto

Hi,
I have read all the mails on the JMF interest group regarding the Broadcaster and DSS.
Well i too am trying to do a similar application. This is an Application
Casting program basically to share my desktop with the other person sitting
across the network using my client. And in order to multicast this, i am
looking at using Darwin Streamng Server.
The whole idea here is that i break the desktop image up into frames and
then compress them and then send it over, protocol used here is TCP/RTP/UDP.
I am trying to hit this stream of packets to DSS so that it can be accessed
else where over the internet. I'm trying to under stand the basic
authentication mechanism DSS uses, so that i can create the .sdp file and
transfer it over to the DSS, which can further be accessed by any client
that can understands sdp.
As i read in the mail some of you were able to create the .sdp file with your custom built boradcaster and send it to DSS if i am not wrong.
I have tried this with Mpegable Broad caster as you said.
Now the problem i had was to create .sdp file with my application and push it to the DSS.
So have you made some kind of a documentation or can you give me an idea as
to how i can go about this. Or it will be even better if you can share the code with me.

Detection problem on HP webcam with JMF

Hi,
I'm trying NyARtoolkit and I need to use the video stream of my HP's webcam encrusted above the screen of my laptop (a HP Pavillon tx 2670ef)
After the installation of JMF, I lunch JMStudio and I manage tu detect my webcam in : File->Preferences->Capture Devices->detect capture devices.
Then i close the windows and i do File->Capture...->I enable "use video device" and unable "use audio device" then i click on "OK" but aftewards i have an error message saying that JMF couldn't initialize the capture device...
2 students with me have the same pb...
I made some researches about this issue and i found this post
http://72.5.124.102/thread.jspa?messageID=10177842
Afterwards I've installed ManyCam and i managed to get a video capture from the virtual webcam simulated with ManyCam.
In fact, when i click on detect capture devices in JMStudio, a windows appears and i can choose "ManyCam Virtual Webcam" instead of "HP webcam".
Moreover, in the options before capturing video, the encoding is in RVB instead of YUV before with the "HP webcam".
But when i run my program i have this error :
java.lang.ArrayIndexOutOfBoundsException: 0 >= 0

Coud you help to use my webcam with jmf ?
josy

You probably want to remove the crust from your web cam if you expect it to work. Most things that are encrusted aren't in the best of shape...
JMF connects to web cameras by wrapping around native interfaces. If the JMStudio isn't able to use your web cam, it could mean a number of things...your web cam isn't compliant with the version of the interfaces (VFW and DirectShow, I believe) that JMF is wrapping around, the web cam doesn't output any formats JMF can use, etc.
But if JMStudio can't use your web cam sucessfully, 99% of the time that means your web cam isn't going to work with JMF... unless you want to code support for it yourself.

VoIP with JMF

hello,
i'm trying to create a J2SE VoIP app with JMF. is it feasible?
i've read that to overcome the NAT problem, we need to use Symmetry RTP. does it supported in JMF?
i've done the SIP session managing with JSIP. now i need to send and receive RTP data.
i've done this for the receiver
url= "rtp://" + IP + ":" + port + "/audio/16";
mrl= new MediaLocator(url);
player = Manager.createPlayer(mrl);
player.realize();
// wait for realizing
while (player.getState() != Player.Realized){
     try
Thread.sleep(10);
} catch (InterruptedException e)
e.printStackTrace();
player.start();
with IP is the other party IP specified in the SDP, and the Port is the port specified in the SDP too.
with wireshark, i've seen that RTCP is seen (Receiver Report, Source Description), and RTCP replies are received (Sender Report, Source Description), but RTP data is not received.
i realize that JMF open the same local port as the port specified in the MediaLocator. while actually in my INVITE SDP, i tell the other party a different port. might this be the problem that i don't receive any RTP data?
Thank you.

Hey,
No, the loss of packets isn't something you can control... you lose a packet, you lose a packet. The different encodings could have an affect on the impact of the packet loss, however, but the actual loss of the packet is out of everyone's hands. Even God loses packets as they travel on the wire...Well, I went again to Wiki to look for that page and you are right, I am wrong, it didn't say anything about packet loss, but it was referring to the call distortion and wrongly concluded something about the packets.
Ummmm, maybe. The issue isn't as simple as knowing the public IP address of a client behind a NAT, it's also a matter of traversing the NAT itself. But if the SIP UAS handles all of that, then yes, you should be fine.after putting it to the test, I'm really confused...
I'll try to lay it out so it would make sense and if that wont work I'll post my code here. there is just a lot of it in a few classes.
This is tested with one way streaming!

Filter with JMF before capture with third-party utility

Hello,
I'm just beginning to work with JMF - played a bit with it, especially with creating effect filters. Now I think need a nudge in the right direction, because it seems I'm stuck on something...
Here is what I'm trying to do (I don't know if it's even possible): I have a simple video effect filter that works on realtime the data from a webcam. Is it possible to somehow register the output stream from this filter as another capture device (?) that can be used in turn by third-party software (movie capture, skype, etc.)? Say, if I have the following:
[WEBCAM] -> [MY EFFECT FILTER] -> [SKYPE]
Is this possible at all, or I'm looking in the docs for something that's just not there?
Regards,
- Alex
P.S. Replies of the type "RTFM" are OK, especially if they contain info where to read, :-)

OK thanks.
I've found a utility that modifes several of the date fields.
Now, I just want to be sure that I don't screw this up...
Which of the several date fields of a file holds the actual shot date?
Which of the date fields is used by the organizer to "organize" the video files (avi and mov's) chronologically?
Thanks for your help

Binary data with JMF

I would like to send plain old binary data using RTP. How can I use the JMF to send binary data without binding it to a codec or media type?

JMF transports data every 10 seconds, why not use a Webservice? JMF transports data every 10 seconds? That's actually news to me, can you present the source of this information?

Is this plausible?Not really, no.
I am looking for a way to stream large content from a server to a webclient to present it. What is the best way? I am using JavaFX as a cliënt.Depends on what kind of content you're talking about. If it's video, that's a different answer than if it's audio, which is different from powerpoint presentations. And your subject calls for an "image server", which doesn't even make sense in terms of "streaming". What does it mean to stream an image?

This looks like jffmpeg fails to load the native libraries via JNI. When this happens, jffmepg tries to find an optional pure-Java decoder (which is not available in for MJPEG) -> Look into jffmpeg.properties. You have to ensure that libjffmepg.so is available in your java library path in order to use the native jffmpeg decoder (will be found automatically).
Also, you could try something like this:
System.setProperty("java.library.path", LD_LIBRARY_PATH);
libname = "jffmpeg";
System.out.println("mapped name"+System.mapLibraryName(libname));
System.loadLibrary(libname);
System.out.println("library loaded");

Play RTSP stream with JMF

JMF does not. JMF only plays RTP-protocol streams.I doubt it.....though I have never tried to play RTSP streams using JMF but seeing following links I do think client side RTSP is supported by JMF:
[http://java.sun.com/javase/technologies/desktop/media/jmf/reference/faqs/index.html#jmf2-rtsp-features]

Webcast with JMF

I'm an under-graduate Engineering student - computer division, and I'm developing a virtual classroom application as a part of my graduation project.
I'm doing most of my project using JAVA techonologies, and I waneted to do the virtual classroom part using JAVA too.
I need to do some kind of video/audio conference using JMF, where users can join the conference, see the instrucor, and instructor's screen, also the instructor should be able to receive requests from participants to grant or deny them.
I was playing around with JMF in the last week and I found some interesting features, I also check the JMF solutions, and I ran some of the RTP stuff offered there, but what I need to do involves something like a webcast, which I could not find anything about.
Need help please
Thanks in advance
J.MAX

My latest thoughts on this (after some hacking):
RTSP server available called VODKA (Video On Demand Kicks Ass) some code is there, a reply from a developer was 'try it' so I think you could get something out of it.
Using RTP I wrote my own sockets controller to count how many connections there are (also sending setup, start, stop and teardown, like RTSP, so the 20-30% cpu of the transcoder isn't always on), you could then send video to each person who asks...) or if you are on the same subnet or VPN then you could multicast.
multiple unicasts would require datasource cloning? I am not sure... hope this helps you work some things out, my solution was to use multicasting with some custom sockets

Getting RTSP servers to work with JMF

I have read through many postings about this, but none of them have been answered. Has anyone gotten JMStudio or any other JMF application to be able to properly recieve video streams in any format from a video on demand server using RTSP? I have tried Darwin Streaming Server (which the JMF faq claims has been tested with JMF, so I take it someone out there knows how to get this working) and Real's Helix Universal Server Basic. I have tried using JMStudio's Open URL menu, and writing a simple application to act as a client.
At this point I would just like to find some server that works with some file/encoding format. Has anyone gotten anything to work? Thank you.
-Brad

I am facing the same problem. does anyone succeed to write a java RTSP player that interfaces well with Darwin Streaming Server?
I don't find any examples of MPEG1 streaming in JMF. Most samples i.e. SimplePlayerApplet.java (param="sun.avi") use local video paths but not rtsp:// URLs.
Samples like AVreceive.java / RTPUtil.java do not use explicit MPEG1 samples and assume that you have an RTP server. And other apps like http://www.alphaworks.ibm.com/tech/mpeg-4 are not fully open source.
What streaming server would you suggest to use? I tried without success to stream a video within a java applet using DarwinSS (ok with .mov, .mp4 but not in java) or RealServers (ok with .rm but also not in java).
In http://java.sun.com/products/java-media/jmf/2.1.1/support-rtp.html it is said that the following RTP servers are compatible with the JMF RTP Player (using javax.media.rtp) but each of them have a serious drawback:
ShowMeTV Transmitter (commercial), IP/TV Server (commercial), vic (Video only), vat/rat (Audio only).
Thanks in advance for any reply

Play rtpdump files with jmf

hello,
I am trying to play a file created with rtpdump (or etheral) directly with jmf. I don�t know, how to create valid datasource and processor objects for a file with stored rtp-packets. Is there a possibility? Do I have to write an own demultiplexer f�r this rtp-dump format? Especially this RTP packets uses the H.263 format.
Maybe there exists a code fragment for this problem.
thanks a lot for your help

I still didn't get it to work as I need it, but I made some progress so far:
Instead of jffmpeg I used the FOBS for JMF Package (http://fobs.sourceforge.net/index.html) in addition with the JMF.
Using this package allows you to play a 3gp-Video in Swing that is stored in your filesystem (!).
I'm still having two problems with this solution:
- I use a Java Webstart-framework and can't acces the user's harddisk, so I need to play the 3gp-Videos directly from memory (they are stored as byte[] in a database), but the current version of FOBS is limited to 3gp-Playback only from filesystem.
- Each user of the application has to download and install JMF and FOBS for their OS (system-specific libraries). Especially FOBS is not always very easy to install, because it needs to change some of the jmf.properites. This can not be done with the JAR-distribution-System of WebStart and I'm expecting problems, when the users try to install both packages on their own.
If you are developing a plain Swing-Application you might be satisfied with the possibilities of FOBS and JMF.
Good luck :-)
