Problems with Audio Codec

[darkpanther]

I have downloaded a divx file, I can see the video without problems, but the sound doesn't work.
I've used BSPlayer but I can't even change the volume of the sound.

I think I have almost all the codecs, but still I can't ear no sound.. Does anyone know what's wrong?

The file information of VirtualDub is:


Video Stream Divx Codec 4.12
---
Audio Stream
Sampling Rate 48k
Channels 2 stereo
Sample Precision 0bit
Compression MPEG Layer-3 Codec (Professional)
Preload Skew 0 Samples (0:00s)
# of frames 0
min/avg/max/tot (no audio frames)

Please help!!!

"# of frames 0
min/avg/max/tot (no audio frames)"


The .avi doesn't have a audio track

[darkpanther]

Is that possible???

Because in the Windows properties of the Avi it says in the Audio Format : Lame MP3 Encoder ACM.

Thanks

[gs0666]

In WMP, can you move the volume control?

[darkpanther]

yes, I can.

Thanks

[gs0666]

If Virtual Dub tells us that we don't have any audio frames, I doubt that there is any audio.

[darkpanther]

I understand, this is really strange.

Those anyone ever had this problem???

Thanks

[darkpanther]

Also when I open the movie in Virtual Dub a get this message:

"VBR Audio Stream detected

Virtual dub has detected an improper VBR audio encoding in the source AVI file and will rewrite the audio header with standard CBR values during the process for better compatabillity. This may introduce up to 3042117 ms of skew from the video stream. If this is unacceptable, decompress the *entire* audio stream to an uncompressed WAV file and recompress with a constant bitrate encoder. (bitrate:4616.1+-1498237.5kbps)"

Do u think that is has anything to do with my audio problem??

Thanks

Maybe(?)VDub cannot handle VBR Mp3...open the .avi in NanDub and post the audio information.I still doubt that there is a audiotrack.

[darkpanther]

First of all , thanks gs0666 for helping me

I opened the file in NanDub and I get this audio information:

Audio Stream

Sampling Rate: 48000Hz
Channels: 2 stereo
Sample Precision: 0bit
Compression: Fraunhofer IIS MPEG Layer-3 Codec
Preload Skew 1 Samples (0:00s)
# of frames: 194370
min/avg/max/tot: 384/13842/1810598400 (2627483k)


Thanks

At least now we have audio :)
Try doing a Direct Stream Copy (both Video and Audio in NanDub)and save the .avi under a new name

gs0666 -

I stumbled on this thread looking for the same information. I have the same symptoms, but my audio is reported as follows:

Sampling rate: 48000Hz
Channels: 2 (Stereo)
Sample precision: 0-bit
Compression: Unknown (tag 2000)
Preload skew: 12000 samples (0.25s)
# of frames: 98861
Min/avg/max/total frame size: 12/1001/12000 (96650k)

I tried what you recommended (at least I think I did), setting nandub to Direct Stream Copy, and AVI audio, and then saving the AVI file under another name. Still no audio.

Any ideas? Any help is greatly appreciated.

Thanks...

You need the AC3 codec installed in order to be able that AC3 sound stream that you have in the video file.

Enchanter -

Sounds good - thanks for the reply.

Only question is, what is the best codec to download for this.
In searching around, the posts I saw indicated that the Nimo codec pack would work, but had adware/spyware in it.

Do you know of any other codec pacs without spyware that would work.

Again, thanks!

[Enchanter]

Speaking from experience, neither Nimo nor Tsunami contain any spywares in them. I have heard of rumors that claim that Nimo contains spywares, but that does not seem true to me...

I've got the same problem here.

Video stream

Decompressor: DivX MPEG-4 3920 Low

Audio Stream

Sampling rate: 48000Hz
Channels: 5 (Stereo)
Sample percision: 0-bit
Compression: Unknown (tag 2000)
Preload skew: 28000 samples (0.58s)
# of frames: 90333 (# of frames in video: 90343)
Min/av/max/total frame size: 23/2335/28000 (206064k)

I've got the AC3 codec installed.

Once again, thanks for you help and following up!

I actually kept searching and found a great site with lots of great utilities, including an ac3 codec download, and auto register and everything. Just downloaded, unpacked with winrar, and clicked the ac3 codec, and... presto - I was up and running with full sound.

For anyone else looking, I found it at:

Try reinstalling the AC3 codec and if necessary, try a different version.
