FFMPEG - libfaac Problem

[JarrodJay]

I have installed Matterhorn on a VPS on one of our Dedicated Servers,
and BBB on an Amazon EC2. Both seem to work fine independently.

However, when following the Matterhorn and BBB Integration
instructions at http://code.google.com/p/bigbluebutton/wiki/MatterhornIntegration,
I ran into some problems.

When trying to run "sudo apt-get install build-essential git-core
checkinstall yasm texi2html libfaac-dev libopencore-amrnb-dev
libopencore-amrwb-dev libsdl1.2-dev libtheora-dev libvorbis-dev libx11-
dev libxfixes-dev libxvidcore-dev zlib1g-dev", I am informed that
"libfaac-dev" can't be found. As far as I can see- libfaac-dev is
included in the lucid packages still? (http://packages.ubuntu.com/
lucid/libfaac-dev).

So I tried to download faac from sourceforge (http://
downloads.sourceforge.net/faac/faac-1.28.tar.gz) and continue anyway,
but when the BBB server tries to run ffmpeg after I logout of a
Recorded BBB Session, I find the following error in the matterhorn log
file (at /var/log/bigbluebutton/matterhorn-process-xxxxxxx.log) -

INFO -- : Executing: ffmpeg -loop_input -t 53.582 -i /var/
bigbluebutton/recording/process/matterhorn/xxxxxxx/temp/canvas.jpg -r

libraries: libfaac.so.0: cannot open shared object file: No such file
or directory\n"]
INFO -- : Success ?: false
INFO -- : Process exited? true
INFO -- : Exit status: 127

(I took out the log ID just to make it read better- it, of course, was
an actual ID.)

So something has gone wrong with my installing of faac, or
lackthereof?

Also- not sure if it makes a difference at all, but in the "Recording
(Matterhorn)" demo page, down the bottom it has "About Matterhorn:
XXX". Should it contain an actual version number, or something? Or is
XXX the expected behaviour?

Any help would be muchly appreciated,
Thanks!
Jarrod.

Anyone got any ideas for me, please?

Hi Jarrod,

Sorry for the delay in responding.  

[ Keep in mind we all volunteer our time to help others here.  There is no service level agreement in these forums.  If you absolutely need a response ASAP, an no one in the BigBlueButton community is responding, you can always contact one of the companies that provide commercial support at http://bigbluebutton.org/support. ]

I just tried the command

   sudo apt-get install libfaac-dev

and it worked on one of our test Ubuntu 10.04.3 32-bit servers.  The problem might be your BigBlueButton server does not have a full /etc/apt/sources.list with the multiverse, and therefore can't find  libfaac-dev.  For help on resolving this, see

  http://code.google.com/p/bigbluebutton/wiki/08InstallationUbuntu#Dependencies_are_not_met

Try the above link and let us know if that resolves the installation problem.  

Regards,... Fred

Hello Fred,

Thank you for the reply. I am very aware and extremely appreciative of
you and the other volunteers. I wasn't "bumping" the thread to make
you hurry up, but more in case my thread slipped by unnoticed. You
doing an amazing job here!

As for the failed dependencies, I clearly need to learn to read
better! I did not see the note about ensuring multiverse was enabled.
That was indeed my problem.

After setting up a test room for recording, I watched the matterhorn
process logs, and they succeeded with only a few errors. It was then
published to the matterhorn server. However, all I have now (and for
the past 2 hours), is my recording in the "Initializing" status under
Matterhorn admin tools. Clicking the status does not show any errors.

There are a few errors that I can see on the BBB machine under /var/
log/bigbluebutton/matterhorn-process (it published fine in the
matterhorn-publish log). The log file is at http://pastebin.com/raw.php?i=fBrZADkE

Any help would be greatly appreciated.

Hi Jarrod,

There is a problem in the last blank video that is concatenated to the deskshare. It has duration=0. 

Executing: ffmpeg -loop_input -t 0 -i /var/bigbluebutton/recording/process/matterhorn/04ee16655ea0f4257e15279af33b37a49010f724-1327452589643/temp/ds-canvas.jpg -r 1000 -vcodec flashsv /var/bigbluebutton/recording/process/matterhorn/04ee16655ea0f4257e15279af33b37a49010f724-1327452589643/temp/ds-blank-end.flv

Could you send me your events.xml file? So I can check deskshare events.

To add some more info- when "Inspecting" the workflow in Matterhorn,
under the "Operations" tab, almost every 'operation' says:
"exception-handler-workflow : error"

But, as Fred said- hopefully 0.8beta4 may help!

Thanks,
Jarrod.
