wma VOICE codec support

[DaveMan]

Hi,

I administer the Linux stations on my faculty (Computer science) and I'm trying to set it up so that students will be able to watch streaming wma video lectures that my university provides.

I can watch the videos with no problem on all lectures but I'm having problems with the audio of some specific lectures.
I can hear all lectures encoded in wma1, wma2 etc.. but the only video lectures I can't hear are the ones recorded with wma VOICE.

Is there a specific codec that I need to add that will get this to work?

I'm using VLC to play the videos with the --rtsp-tcp flag.
The videos are using the MMS extension but I used a greasemonkey script to rename the links to RTSP ones.

Everything works great other than the audio on the lectures encoded with wma voice.
I tried googling it and everything I got was about wma, nothing specific to wma voice.

Anybody can help me?

Thanks.
Dave.

Codec ?

[DaveMan]

not codec?
doesn't really matter to me, I'm just trying to get it to work.
Any idea how to do that? We have invested a lot of time getting this far, it would be a shame to fall because of this.

[Jean-Baptiste Kempf]

What is your Codec ? What is your FourCC ? What are the info that VLC gives you on those files ?

[DaveMan]

VLC shows the audio codec to be wmas as posted on:
viewtopic.php?f=13&t=42215
Sorry for the double post, I just though I'd attack the problem from a different angle.

Windows recognizes the audio codec to be: Windows Media Audio 9 - Voice 20 kbps, 22 kHz, mono

Thanks a lot for the help.
If this works, it will solve many problems for me.

Dave.

You need wmspdmod.dll and it should work.

[DaveMan]

Thanks a lot!
I will try it out!
Where should that file reside? in what directory?
I remind you that I'm running Linux and not windows.

Thanks.

Apt-get install w32codecs or similar...

Hello,

can the above solution help me on an XP station, from which I am trying to multicast an incoming MMS stream which contains WMA to my intranet?

The original stream is encoded in wma2 44khz 32kb/s, mono (A/V) 1-pass CBR 16 bits per sample Windows Media Audio 9, video is WMV3, Windows Media Video 9 Res.384x288.

The receiving clients are getting no voice , only video when VLC duplicates that MMS stream with VLC as the multicast server like this:

Code: Select all

:sout=#duplicate{dst=std{access=udp,mux=ts,dst=239.255.255.255:1234,sap,group="MOU"}}

Would I have to put the DLL into the vlc\plugins menu or the system32?

Thank you for your help.

Kind Regards,

Brahman

My problem is the same as in a previous post. I try to view mms://194.116.83.15/Hard%20and%20Heavy in VLC Player and getting no sound
In the begining of output (channel teaser) i hear а sound, but then a main content is begins sound is off.

Info about stream id shown:
Sound: wma 44100 16bit 256kbps
Video: WMV3 450x320

In Windows Media Player this URL is shown perfectly, but i want to multicast it in my LAN.

Can you help us ?

System32 is enough.

Hi
Thanks but installing w32codecs did not help.
Any other ideas?
Will getting that dll file work? and if so, where should I put it on my Linux system?

Thanks a lot.
Dave.

[DaveMan]

Sorry to bump my own post but I would really appreciate some help.
Thanks.
Dave.

[Jean-Baptiste Kempf]

without the messages of debug, how can we help you?

[DaveMan]

The error I am getting is:

[00000298] main decoder error: no suitable decoder module for fourcc `wmas'.
VLC probably does not support this sound or video format.


Full Debugging messages follows.
Thanks a lot, if this manages to work, it will solve many problems for me.

[med007]

Running VLC in mac os X tiger.
error message:
"main: no suitable decoder module for fourcc `wmas'.
VLC probably does not support this sound or video format."

I get video but no sound when trying to open .wmv file. Similar problem in quicktime and mplayer.

I get this error and I really need to be able to play these .wmv files in VLC.

Also, when I convert these files to .avi, I cannot properly increase their speed. When I increase the playback speed I lose the audio - you only see the video.

Can someone please make it so that you can change the playback speed similar to WMP 11 and Quicktime?

[Jean-Baptiste Kempf]

Don't multi-post!!!

OSX doesn't support wma voice.

[DaveMan]

Any info on my problem?

Thanks.
