Getting started with vorbisfile_example.c (MS VC 6)
Hello
Hope you don't mind another newbie's question.
Further to GIE's email about problems compiling decoder_example.c example
(MS VC 7) using debug static ogg/vorbis libs, we'd appreciate any help
getting the example files to compile on MS VC 6.
The zip files we have downloaded are:
libao-0.8.2.zip
libogg-1.0rc3.zip
libvorbis-1.0rc3.zip
vorbis-sdk-1.0rc3.zip

Introducing ov_open_callbacksp and ov_clearp
Hello,
I've been looking to the libvorbisfile and got into troubles when trying to
use it: I need to compile it on a PalmOS and the libvorbisfile must be
compiled in ARM whereas calling code is in 68K. This implies that the
interface ov_open_callback is not usable because the OggVorbis_File *vf must
point to something in the target architecture (ARM) whereas the caller
cannot do that.

Kenneth's Second Commit
I've fixed a heck of a lot of stuff in the time frame of just over ten minutes.
And you all care... right.
I actually ran Vorbize, and discovered some stupid bugs (e.g., segfault???).
Fixed.
Both Vorbize and Ogg123 should now speak fluently in Monty's comment-eese.
I'll be working on getting both to implement all the comment tags; I'm
seriously considering dropping all comment

Problems with vorbisfile and files smaller than CHUNKSIZE
-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1
Hi,
I'm writing a simple application to decompress a set of Ogg files to
raw PCM format, using vorbisfile, because that is the simplest way of
doing it. These Ogg files are sounds for a game, and thus sometimes
very short (about .25 s).
However, vorbisfile has severe problems with Ogg files that are
smaller than the CHUNKSIZE which is #defined

ov_open error
Hi,
I put together a small a Visual C++ 6.0 project that uses the code from
vorbisfile_example.c. I open an ogg file in binary mode and when ov_open
gets called, it always fails. I then put together another project and
compiled vorbisfile so I could see where the error was occuring. It is
happening in _fetch_headers when it calls ogg_stream_packetout. The return
values is -1, which means there

ov_open_callbacks takes so much time to open 210 MB OGG file
Why ov_open_callbacks(fd_, &vf, NULL, 0, OV_CALLBACKS_NOCLOSE) takes so
long to open OGG file?
The OGG file has just 210 MB. It takes a lot of time open the file.
I am working on OGG audio recorder and player.
Thanks in advance!
With kind regards,

predictability of buffer size for decoding
I am wondering if buffer size for my decoding to pcm can be predicted dependably as follows. So far, the one problem I have had is when I have played a file of only about 5k. The buffer was a little less than 10% too small. I "solved" that by padding the result with an extra 20 percent. However, I have been told that I should be able to rely on the value of ov_pcm_total.

ogg vorbis decoding
Hello,
I am currently developing a ogg vorbis decoding module for use in
winlame (a LAME frontend), and I have some questions:
To do a decoder I used most code in decoder_example.c, but I think
there is something missing. I would be glad if someone could look at
this code:

ov_open fails on Version 1.0.1
Eddie,
I have been reviewing vorbis list postings, because I have been spinning my wheels for a week, trying to make a simple insertion of ogg vorbis decoding (vorbisfile) in the audio class of my MFC/C++ program. I just read your thread from April 2004.
Question: Do you have anything you could send me, since I assume you succeeded in getting results? And/or could you take a look at what I

How can I seek in Ogg Vorbis file, but not using Vorbisfile library?
Hello, All.
I am making an Ogg Vorbis decoder based on Tremor. The Vorbisfile library provides a high-level API which enables us to seek in the file, but it needs to declare a pointer to OggVorbis_File structure.
Because I am supposed not to use file, so I can't use the ov_pcm_seek() or ov_raw_seek() functions to seek in the file. For decoding an Ogg Vorbis file, I first put it in

XMMS plugin update
Tony,
I committed a new version of the XMMS plugin. This is a cleaned up and
debugged version of the code you sent me with the conversion to the vorbisfile
app library.
At this point, it properly handles chaining (try concatenating two vorbis files
with different serial numbers to see it work). The code also got alot smaller
as alot of the hairy stuff is now done by vorbisfile.a.

lack of detail for exception in ov_open
I am having one frustrating time trying to decipher why ov_read is failing in my MFC/C++ application, and I see in Google results that others have had difficulty as well. These google discussions generally involve libraries, dll's and linking options, as though there are perhaps some basic incompatibilities between ogg vorbis and win32 and/or MFC/C++. Very confusing.

Vorbis Block Diagram
Hi,
I have looked through the documentation available from the downloads and the
web and haven't yet come across a block diagram which shows exactly how the
process of going from a .wav file to a .ogg file works. I suspect it is the
same as the mp3 process (with a different psychoacoustic model). I found

Vorbis on OS/2
Following a few months of lurking on the list, and vainly trying to get vorbis to compile
on os/2, I finally managed to get the nightly gzip from saturday to compile (fairly)
cleanly, and so have finally been able to play with Vorbis on my OS of choice :)
Using the EMX runtime system, and bash for OS/2 (along with a few ported GNU apps),
both configure and make work fine (except for ogg123

Application Crashes When Calling ov_time_seek() function
I’m running into a problem with my application crashing when I make a call
to the ov_time_seek() function.
The call includes the OggVorbis_File and it is indeed seekable, as I first
check that using the ov_seekable() function. Everytime, however I try to
seek forward, the application dies with a core dump. I’m working with the
example from the “VorbisFile Documentation” site.

vorbis-tools/Makefile.in glitch...
I'm updating my vorbis rpm spec file, and when I try to do "make -C

Mac Ogg Vorbis Player
Well, I updated the player to work with the branch_postbeta2, but it
contains some nasty kludges to the project files that probably shouldn't
be finalized. I'm going to put it in a separate file
(http://oscar.the-rileys.net/programming/vorbis_pb2.tar.gz) for now.
Unfortunately, this release doesn't seem to fix the "tearing sound"
problem. I think this might be related to

Makefile dependencies in vorbis-tools
I've been trying to tackle the vorbis source. I ran across what I think is a
missing dependency in the vorbis-tools directory. Since ogg123 and vorbize
are staticly linked to libvorbis and vorbisfile, when those file change, the
executables should be rebuilt. Below I've attached a patch. (I hope it
works. I am sort of new to patch and diff.)
BTW, I've been trying to find a good

Problems running example encoder/decoder
There isn't a lot of guidance on how exactly to run the codec I compiled out of
cvs just now, but I expected the following to work:
cat test.wav | encoder_example | decoder_example
But the decoder fails with:
End of file before finding all Vorbis headers!
Is this a bug? Or am I missing something fundamental? Should I attach the
test.wav?
