MPEG-4 content over a network with EMB

rcbeuker Oct 25, 2004 3:46 AM

I am looking for a solution to stream MPEG-4 content over a network and found out about EMB. I was wondering if there is an EMB solution available on Jboss. I studied the JSR documentation (http://jcp.org/aboutJava/communityprocess/first/jsr086/index.html) and the reference implementation from IBM (http://www.alphaworks.ibm.com/tech/emb). What is the status of the Jboss Media module? Although I am using Jboss, I never did some development for it. Maybe it is a good idea to contribute the work I have to do to the Jboss Media module. Which steps do I have to take?

Regards,

Roland Beuker

We had some guys implement an EMB solution about 6 months to a year ago. Not sure how complete or robust it is. It is distributed with JBoss 4. If you're interested in taking it over give me a buzz. bill@jboss.org

I have to check if the current available code matches my planned video streaming solution. Therefore, I will get the code from CVS. What about the current maintainer (Ricardo Arguello)? Does he have some information? If the current status is suitable I will take it over, otherwise I have to start a new module?

If the current status is not suitable make it so. We don't need multiple implementations of the EMB.

5. Problem with CVS

rcbeuker Oct 26, 2004 9:47 AM (in response to rcbeuker)

I have some problems while getting the media contents from CVS. According to a mail (from Scott Stark) the media module name is jboss-head. However, when I browse the CVS Tree I cannot find the jboss-head module. Indeed, there is a module called jboss-media. Do I have to use this one? When I try this (I try to access CVS services from behind a firewall) with TortoiseCVS CVSROOT:

:pserver:anonymous@cvs-pserver.sf.net:80/cvsroot/jboss/jboss-media

The server keeps asking for a password:

In C:\Documents and Settings\Roland\Desktop: "C:\TortoiseCVS\cvs.exe" "-q" "checkout" "-P" "Desktop"
CVSROOT=:pserver:anonymous@cvs-pserver.sf.net:80/cvsroot/jboss/jboss-media

cvs checkout: Empty password used - try 'cvs login' with a real password

cvs [checkout aborted]: authorization failed: server cvs-pserver.sf.net rejected access to /cvsroot/jboss/jboss-media for user anonymous

Error, CVS operation failed

What do I have to change?

Ok when using:

:pserver:anonymous@cvs-pserver.sf.net:80/cvsroot/jboss

With module:

_jboss_media

It works.

cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/jboss login

cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/jboss co jboss-head

jboss-head is not a module, but an alias (or whatever you call it in CVS).

XinLab's Java Mobile Media Processor (JMMP) is a good example when thinking of an EMB implementation. Take a look at their datasheet:

http://www.xinlab.com/prod_mo_sdk.html

This gives a clear idea what is possible with EMB.
