Content Manager Video Media Sound Issue
« on: March 17, 2010, 11:55:44 AM »
I want to be able to upload a video directly into Content Manager, and resolve the issue below.
I am running audio through a line-in source.  When a video comes up I need the line-in audio to stop.  Now whats happening, is the audio from the line in and video are both playing. 

Thank you
Mark

Hi,

since release 5 we have "Audio Ducking":

There is support for Audio Ducking, meaning turning down the volume of other audio (typically background audio tracks) when another media item is playing. You can now specify any of the following:
Mark a Media Item so that it always causes audio ducking when it plays.
Mark a Playlist Item so that it causes audio ducking when it plays. it plays.
Mark an Event Trigger or Time Trigger so that causes audio ducking when it occurs.
Mark a timeslot so that it causes audio ducking for its duration.



Hope this helps,
Thomas

I know on one player it works, on the other player it doesn't.  In this case its the test player it works, on the live player it doesn't.
Its either a hardware of software issue.  The player is patched to the latest.

Hi Mark,

is it possible that you've defined the channel with "Mute audio from visual media" for the live player?

I just checked, and its not checkmarked in the channel settings.  The file is a vob media file, I noticed the system where the sound works, has the Divx codec, the system where it doesn't have sound, does not have the codec.  Could this be a codec issue?

Hi,

It may happen that the divx decoder will pick the *.vob directly while the other player doesn't know how to play *.vob.

Easy solution:
just rename the *.vob to *.mpg to make sure the right decoder applies to the file. Sounds not too sneaky but it works.

Cheers,
Thomas

Thanks for the tip.  We renamed the file and it loaded into Content Manager as name.mpeg.vob
I updated the Codec from Scala, I converted the vob files to avi, mpeg and mov.  There are still problems playing them correctly.

Just rename your "name.vob" in "name.mpg" and not to "name.mpeg.vob"
(make sure you see the extensions of your files !! that's why your file was not renamed correctly)

BTW: mov will not work

Cheers,
Thomas

Thanks for the information.  Going to try that out now.

The video file played incorrectly when correctly renamed to name.mpg.  I know that Scala doesn't officially support the AC3 audio codec.  Do you know which  codec to install on the Scala player to get AC3 to work?  It appears most video files use AC3.  We did put Divx on the player, but when the video played, the sound was 5 seconds behind the video.

Thanks

Hi Mark,

normally there is one rule: whatever you may playback in Windows Media Player (without retrieving new codecs on run time), will run in Scala.

First make sure you have installed the actual version of Scala's "Release_5_1_scala_videocodecs_update.exe" (if you are running 5.1).

Then do the WMP test: After installation make sure, the file and/or the DVD itself is playable with WMP.

In former distributions Scala has bundled a DVD player package with it. It has been removed due to the support above. If this doesn't help already, I think you should have a good DVD *.vob and AC3 decoding with any good DVD package like WinDVD, PowerDVD etc. Do the WMP test again.

hope this helps

Cheers,
Thomas

BTW: In certain cases I use a very good tool called xmedia-recode. You'll get it as freeware from http://www.xmedia-recode.de The program is multilingual and supports DVD transcoding to h.264 for instance.
