mpeg-1 layer 2 problem
 

hi again!

after installing and uninstalling various codec packs for another problem, my pc seems to have a problem with mpeg-files, which are made with the mpeg-1 layer 2 audio-codec.

as far as understood the other posts about this codec, it is one of the most standard codecs around and usually is installed with windows. well, guess what: bsplayer provides me only with video, but leaves out the audio!

my questions are:
- how is it possible that this codec was deleted?
- how can i fix it?

my specifications are:
AMD XP 2000+ CPU
1024 MB DDR SD-RAM
Geforce 2 TI 64MB Videocard
I run BSPlayer 0.86 build 501

my video-codecs are:

Hi!

I'm not sure, but I think that the MP3 codec installed with windows only supports MPEG1 Layer 3 audio (short MP3), but you're refering to MPEG 1 Layer 2 or MP2.
But as I said I'm not 100% sure if this is true.

No, it is about an MPEG 2 codec. Windows don't have something like that. You must install one. Search for topics about mpeg2 and find there links to download.

I'll try that!

that doesn't work. I downloaded and Installed Elecard MPEG2 Video Decoder kit ver 2.0.

I am able to play other audio files that use the MPEG-1 layer 2 codec, but this particular file is played withoud sound.

Again, I tried the file on another PC and it worked fine. I tried the file on other players, but still no sound.

On the pc it worked, right-click on the movie window, go to properties and there you have the codec used to play the file.

doesn't work either.

on the pc where i can hear the audio, the codec used is morgan stream switcher. after installing the codec on my own pc, i still don't hear audio. but when i right-click and click on properties, the codec used on the pc is Moonlight Odio Dekoda

Strange thing. Morgan stream swicher is not a codec but a stream swicher. It swiches between two audio chanels in one audio file. And it has a huge problem working with bsplayer. Odio dekoda is mp3 decoder supplyed by Elecard. Try using win media player you should have the MMS loaded and you can use it to swich the audio.

i have both the elecard and the MSS-codec installed, but when I play the file with Media Player I don't get to choose codecs (or streams), it just plays the file with Moonlight Odio Dekoda.

Is there any way you can cut something like 2-3 MB of your file and send the piece to me by email ?

the only way i know to do that is with VirtualDub, but than I get an .avi-file and it's still huge if I have to use the same codecs (as in approximately 100MB).

funnily enough my stereo (whick provides my pc with the sound) actually shows sound activity, but you can't hear it. also, this sound activity is only on the right side (so it's mono). i'm sure it's not the fault of my stereo, because it plays every other sound.

here are some more specifications of the file:

I fixed the problem by deleting 2 identical VideoCodecs!

Thanks for the help everybody!
