Full Version: Program to analyze ogg files?
The title pretty much says it all. Is there a program I can use to analyze ogg files to see how they were encoded and to make sure they're ok? I didn't see anything here, at vorbis.com, or at RareWares.
Since there really is only 1 encoder, that isn't really necessary. By looking at the vendor tag of an ogg file in any player, you can see the used Vorbis version, e.g. Xiph.Org libVorbis I 20020717 which is Vorbis 1.0
All GT versions also identify themselves in that way.

dBpowerAMP Music Converter will tell you which bitrate (vbr cbr) and the version of the library used.
What are you needing that ogginfo.exe doesn't offer? It's part of the vorbis-tools pack downloadable from www.vorbis.com. Here's my output from it:

i think you don't have to analyse them because the information is already stored in the files. so you just have to read it out which every player can
eg winamp
Length : 4:38
Average bitrate : 184 kbps
File size : 6,432,185 bytes
Nominal bitrate : 192 kbps

Sampling rate: 44100 Hz
Serial number: 29355
Version : 0
Vendor :
Xiph.Org libVorbis I 20020717
what else do you need ?

why not using your own ident? (like libvorbisGT3 or something)

Maybe I didn't explain very well. This is how GT3 identifies itself.
Xiph.Org/Sjeng.Org libVorbis I 20020717 (GTune 3, beta 1)
Since it's based on the reference libVorbis I library of 2002-7-17, it makes sense to have that in the version string.

I have the same question.
What happens if the data stream is corrupted, for example, when downloading from internet?
A lot of MP3 files that I download from internet are corrupted (defective frames), and I'd like to know if there's a way to check that with ogg files.

"ogginfo" scans the whole file and will tell you if it is damaged.
Thanks.
I've downloaded a dozen of ogg files, and half of them seem corrupted.
An example:
All corrupted files have a hole in an offset position bigger than the data length. Is this possible? (I guess that file is also bigger than data length because of header, but I don't know...)
The worst example I found:
Is it normal then those errors at the end of file always?
Is there an easy way to know errors position in time format?
Any graphical front end for ogginfo?

Lots of people corrupt ogg files by appending ID3 tags. Strip the tags, and the stream should be okay.

That looks more like a seriously damaged file.
QUOTE(minix @ Jan 28 2003 - 05:16 PM)

No. Only when people append garbage to the end of the file (ID3 tags are common).

None that I know of.
So... how would one go about removing the tags from an ogg file? (I just recently tried using the Lyrics3 plugin for winamp, and was slightly disturbed by the way it broke playback of any ogg file it retrieved the lyrics for...)
Can someone post a link to a win32 binary of ogginfo? I can't find one that isn't broken.
Thanks!
Thanks!
danke man!
