java.lang.UnsatisfiedLinkError: no xuggle-xuggler in java.library.path

[worldo...@googlemail.com]

I've seen the FAQ entry about this - but i'm not sure how to ensure
that i'm using the xuggler correctly within Red5.

If i have a webapp and i want to use xuggler's capabilities within it:

which xuggle jar files do i need?
where do i put the xuggle jar files?
do i need to create a war file?

any help here would be much appreciate - i've installed the correct
'bit' version on my mac - and can run the simple test example. But
when running in Red5 i always get the unsatisfied link error, despite
trying all sorts of combinations of jar files and locations.... so
wondered if i could get some help from the source.

Hi Trevor,

It likely means you don't have DYLD_LIBRARY_PATH set correctly when running Red5.  That variable needs to point to where the .dylib file (the native component) for Xuggler resides.

ah, ok, this is probably a result of my mac newbness :)

other than this everything has been pretty smooth - refreshing to watch several minutes of tests all passing! Not at all what i'm used to :(

thanks Art

No problem.  let us know if you run into any other issues.

FYI on Mac's you need to pass in a special flag if you're running 32-bit Java 1.5 (as opposed to 64-bit Java 1.6).  If that happens, do:
ant clobber
ant -Dbuild.m64=no run-tests
ant install

to build a 32-bit version of xuggler.  This only applies to Mac's.

[Trevor Burton]

Yeah, i caught that one - and that's how i've been building it so far....

Oh, I feel like one of those Hi I'm a Mac, and I'm a PC commercials
right now...

Xuggler 2.0, Red5 0.8RC3, checked out SVN examples about a week ago.

I am trying to hack Transcoder.java and swap it in place of the
videotranscoder demo for some tests. Using Xuggler 2.0 and SVN
examples from about a week ago. I remembered the FAQ and went through
it:

"Did you install the Xuggler? If not, follow the instructions here."
Yes, version 2.0. :) And rebooted of course...

"Is the environment variable XUGGLE_HOME defined and pointing to your
Xuggler install directory (usually C:\Program Files\Xuggle on Windows
or /usr/local on Linux/Mac)?"

C:\Documents and Settings\me>set XUGGLE_HOME
XUGGLE_HOME=C:\Program Files\Xuggle

"Does your PATH environment variable include %XUGGLE_HOME%\bin"

C:\Documents and Settings\me>set PATH
Path=C:\Program Files\Xuggle\bin;C:\WINDOWS\system32;C:\WINDOWS;C:
\WINDOWS\System32\Wbem;C:\Program Files\TortoiseSVN\bin;C:\Program
Files\Java\jdk1.6.0_13\bin

I'm compiling with ant/build.xml. I can deploy non-xuggle stuff to
WEBAPPS just fine.

C:\program files\Xuggle\share\java\jars\xuggle-xuggler.jar is present.
I'm stumped...

This is a bug I meant to deal with last week but, um, forgot to.

The tip of tree of Red5 assumes Xuggler 1.x is installed, not Xuggler
2.x and the two releases are not binary compatible. As a work around
(assuming Windows and both vars are defined):

copy %XUGGLE_HOME%\share\java\jars\xuggle-xuggler.jar %RED5_HOME%\lib

or (Linux/Mac):

cp $XUGGLE_HOME/share/java/jars/xuggle-xuggler.jar $RED5_HOME/lib

At some point I'll check in a change to Red5 that brings is up to Xuggler 2.0

[6pixel]

Unfortunately, still no joy (rebooted too). Same error.

Is there any other information that would help narrow the problem?

[Art Clarke]

Can you paste the errors from Red5 you're seeing now. If Red5 is
actually loading Xuggler 2.0 then the error message you had before
will look different. If it's the same, then you didn't copy
xuggle-xuggler.jar to the right location.

Sure, error is the same I think, pasted at end for sanity check.

The system cannot find the file specified.

(bizarre.... so I copied the JAR to my Red5 install manually through
windows explorer, then after no joy through the command prompt)

Remove the xuggle-xuggler-1.22.237.jar file

By the way, it appears that Red5 moved to a new version of MINA last
week, which also appears to have broken our Red5 demos. I'll take a
look at it over the weekend.

Deleted it, though it didn't help.

xuggle*.* in my RED5_HOME:
\xuggle-xuggler.jar (why is this here?) (192kb)
\lib\xuggle-xuggler.jar (192kb)
\webapps\videotranscoder\WEB-INF\lib\xuggle-utils.jar
\webapps\videotranscoder\WEB-INF\lib\xuggle-xuggler-red5.jar

Would there be anything to gain by uninstalling/removing Red5,
Xuggler, wiping out my copy of SVN, then reinstalling/rechecking-out
all?

Sounds like the MINA problem would just be a new hurdle to face...
BUT... at least it'd possibly be finding Xuggler 2.0 before running
into that problem, right?

This machine is pretty clean-loaded, but at one point it did have
Xuggler 1 on it, removed it before installing 2.

And after you deleted it, do you STILL get the same error text. If
different, paste the error here. The error text message for that
error changed between 1.x and 2.0 so I'm surprised to see the old
message.

If you still have the old text, then somehow it appears that Red5 is
getting the wrong jar file.

Art,

Yes, it was the same error exactly (pasted at end for sanity check). I
think I remember another post where a user actually reloaded their
computer and it worked. While I can't go to that extreme, I did wipe
out my Red5 installation, uninstalled Xugger 2, rebooted, reextracted
Red5 and reinstalled Xuggler 2, rebooted, deleted my local copy
(xuggle-xuggler-red5) and redownloaded from SVN (HEAD, Revision 362),
then ran the ant build that installs the apps to RED5_HOME (install-
java target).

This time around I notice I can't seem to build.
BUILD FAILED
C:\eclipse-jee-ganymede-sr2\workspace\xuggle-xuggler-red5\mk\buildtools
\buildhelper.xml:278: The following error occurred while executing
this line:
C:\eclipse-jee-ganymede-sr2\workspace\xuggle-xuggler-red5\mk\buildtools
\buildhelper.xml:1057: Execute failed: java.io.IOException: Cannot run
program "sh" (in directory "C:\Program Files\Xuggle"): CreateProcess
error=2, The system cannot find the file specified

I'm not on 'nix, so not finding sh is understandable - but this time
around it's a fatal error, before it continued to compile. Is this a
potential source of the problem?

Before redoing everything, I noticed the ant build updated 3 jars in
my %XUGGLE_HOME%\share\java\jars: xuggle-xuggler-red5.jar, xuggle-
utils.jar, jetm.jar. I am assuming this is normal, non-harmful
behavior (ie, no version conflicts?).

Of interest: audiotranscoder works.

Thanks for your help and patience, it means a lot.

I just checked in a attempted workaround to the build problems for the
xuggle-xuggler-red5 stuff, you can try that. Although bear in mind
given the other reports coming in today the Red5 demos aren't working
with the latest Red5 code because mina ByteBuffers are no longer
available in Red5.

I'll try to fix this weekend but no promises folks.

By the way, normally I'd suggest using the installer that comes with
Red5 to install the audio and video demos.

Thanks Art. I can wait until you have a chance to go over things.
Keeping up with the FFMPEG and Red5 teams' changes seems very
challenging right now.

By the way, do you have a paid consultation service available?
