Well, it is a bit complicated issue, if you want to have all codecs
supported.

Available FFmpeg binary distributions lack the AMR narrow band codecs
due to patent issues. You may get the AMR-NB libs separately, but to
have it all working together you must compile FFmpeg yourself. Below
you'll find the detailed recipe (courtesy of Dr. Pepix) how to make it
for CentOS 5 and other related systems.

Enable amr-nb in ffmpeg
-----------------------

- get the rpmforge repository definition

(follow the indications given at https://rpmrepo.org/RPMforge/Using)

- install ffmpeg in the devel machine with all its dependencies

yum install ffmpeg -y

- get the amr-nb binary libraries (runtime and devel)

yum install amrnb amrnb-libs -y

- get the ffmpeg source code

wget http://dag.wieers.com/rpm/packages/ffmpeg/ffmpeg-0.4.9-0.9.20070530.rf.src.rpm

- "install" the source code in order to gain access to the spec file

rpm -i ffmpeg-0.4.9-0.9.20070530.rf.src.rpm

- edit the spec file in order to enable linking with the amr-nb libs

cd $RPMHOME/SPECS # usually /usr/src/redhat/SPECS
$EDITOR ffmpeg.spec # I recommend /usr/bin/emacs :)
# add the line "--enable-libamr-nb" after the
# line that reads "--enable-gpl"
# it's strongly recommended to change the
# package release, e.g.: 0.9 -> 0.9b

- build the new rpm

rpmbuild -ba ffmpeg.spec # the rpm will end in $RPMHOME/RPMS/<arch>/ffmpeg-...

Install FFmpeg with all the bells and whistles
----------------------------------------------

- put the new ffmpeg and amr-nb rpm packages in the target machine

# remember: scp is your friend!

- get the rpmforge repository definition

(follow the indications given at https://rpmrepo.org/RPMforge/Using)

- install ffmpeg in the target machine with all its dependencies

yum install ffmpeg -y

- erase the standard ffmpeg rpm

rpm -e ffmpeg

- install the new ffmpeg and amr-nb libraries

rpm -i ffmpeg-... amrnb-...

I understand you'll be using our standard alembik-client.jar. If so, you
can find a few code samples here:

Jakub - Thanks a bunch for your quick reply and helpful code, I appreciate
it.

I've run into a problem with transcoding videos. Every time I run the
client code, I get the following response from my Alembik server: "Job
return code is: 5000 - ERROR: Unknown codec parameter value"

My feeling is that the problem lies with my ffmpeg install. I'm using the
latest source, which uses libavcodec version 51.60.0. It seems that this
version of the codec libraries is not supported by Alembik. How should I
proceed? Is there a quick fix or do I need the old libraries? If I need
the old libraries, or an older version of ffmpeg all together, could you
point me to one?

I appreciate any help you can give me.

If you define codecs manually (via Video.VideoVisual.setCodec(...)),
please be sure to use proper values. Refer to our internal contants set
for those prefixed with VIDEO_CODEC_ and AUDIO_CODEC_:

Well, the problem with FFmpeg is that from time to time they change the
syntax of the execution command line, so different versions of that
software have to be handled in a special way. 
 
In future we'll try to add support for subsequent FFmpeg releases more
frequently, but for now I suggest grabbing one of the supported ones
(preferably 51.48.0). 
 
Which operating system are you using to host Alembik?

Thanks for the quick response Jakub.

I'm hosting Alembik via Glassfish on an Amazon Elastic Cloud Compute
instance running CentOS 5.

I verified that I was using the proper codec values in my calls, still
getting the same error.

I've been trying to find a version of ffmpeg with the 51.48.0 libvacodec
version, but haven't had any success. Do you think you could point me
towards one?

Thanks for your help.

Worked like a charm, thanks Jakub.

I'm now trying to add streaming support on my Alembik install. How well has
streaming been working? Do you have any client test code I could take a
look at?

Streaming works fine. You just have to install and adjust Darwin server
and MP4Box application as the on-line documentation describes. 
 
As for the client code it does not require much coding. You may either
use the following TranscodingManager's method: 
 
public static TranscodingRequest prepareUARequestStreamingVideo
(String sourceUrl, String userAgent, Long maxSize) 
 
or just add the "Streaming" transformation to a given TranscodingJob: 
 
Transformations transformations =
TranscodingUtils.getTransformations (TranscodingUtils.getMedia
(job.getTarget().getTranscodingParams())); 
Transformation transformation = new Transformation(); 
transformation.setType (TranscodingUtils.TRANSFORMATION_STREAMING); 
transformations.getTransformation().add (transformation);
