AW: access violation in ov_open
hmmm...when using my self-compiled *_static lib's all works fine.
(the shipped *_static lib's conflict with my libcmt.lib because of
multiple definitions of some functions)
only the dynamic libs cause an access-violation in NTDLL

access violation in ov_open using VC6
I passed a valid FILE* (from fopen() with "rb") and the
address of an OggVorbis_File struct, but an access
violation occured when ov_open is called.
I have enabled the Multithreaded, but it still doesn't fix
the problem. I look at the vorbis_comment.exe source and I
see vcedit_open() function and other vcedit_*() functions
everywhere. I am assuming that there is known issue with VC

Fw: ov_open failing with all files
Hi,
I'm experiencing (what I think), is an odd problem. Whenever I try to open a
plain ogg file with the code below, it is failing with OV_EBADHEADER.
I am able to open (and play), blowfish encrypted files using the
ov_open_callback (and openssl BIO functions), so I thought maybe I had
struck some silly problem with the default FILE * handlers.
So I whipped up a basic callback handlers for

Problem with 'ov_open'...
Hey, I've coded an OGG player for Win32 (it uses AL for playback so it's portable to Linux/Mac), but every time the program gets to the 'ov_open()' function, the app completely freezes, and I have to use the task-manager to kill it. I am supplying it with a valid file handle that was just opened (FILE*) and the vorbis file is also a pointer that is not in use (set to null). Any

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.

Ov_open crash in windows
I am getting the following error from MSVC when calling ov_open()
from my app:
Unhandled exception in Progname.exe (KERNEL32.DLL): 0xC0000005:

The call stack shows:

I am running Win98 and v1.0 off the vorbis libs. The app is single-

ov_open throws exception (Compiler VC7)
Hi
I try to load an ogg file with the vorbisfile library like this:
FILE *f = fopen("test.ogg", "rb");
if(!f) ...;
ov_open(f, &vf, 0, 0);
But ov_open always throws an exception. Im pretty sure its a compiler
problem because the same code worked on VC6. Im compiling my programm with
the multithreaded dll option as mentioned on the mailing list bevor.

ov_open from memory
Hi folks,
i would like to know if it is valid to load a whole .ogg file into memory
and call ov_open like this:
ov_open(NULL, &OggVorbisFile, pRawData, RawDataLen);
An other question is, is it valid to copy some ogg files into one (resource)
file, position the filehandle and use ov_read to read only the ogg file
which starts at the current position of the file handle? (In other words,

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

Direct crash on ov_open
Greetings,
I've just downloaded the Ogg/Vorbis Win32 SDK 'OggVorbis-win32sdk-1.0.1.zip' and
made a test app to open an ogg file. But as soon as I call ov_open() the program
crashes because of an access violation to address 0x00000010...
This happens on both Release and Debug builds.
The test app is simple:

Speed up?
Hello,
hope you're fine.
And hopefully someone can help me.
I wrote a short demonstration to show you my problem (see below). I'm
asking always for 64 samples. When "ov_read_float()" is finished, I
want to seek back to sample 1, and ask immediately for the next 64
samples.
But when I run this small app, I get an totally high CPU load.
Is there a way to it speed up?
Or do I

Documentation Suggestions
I'm a developer for a game company and I'm almost done adding support for
Vorbis to our game engine. As such, I wanted to simply plug in the read
function, let it decode, and then send the PCM data on to DirectSound just
like I always have. There were several occasions where I spent 4 or 5
hours trying to fix a bug, digging through newsgroups and sound-format
specs, when that info could

Reading from memory and ov_open
Hi,
I've been working with oggvorbis-win32sdk-1.0.1 and have a
semi-hypothetical question.
Let's suppose that, for whatever reason, I've allocated a block of
memory, and I've loaded into this memory a perfectly valid ogg vorbis
file.
Now I'd like to decode this vorbis data, but I'm stuck calling ov_open()
because I don't have a FILE*, I have a block of memory. (This

ov_open fails on Version 1.0.1
Hi,
I've just got around to moving from version 1.0 to 1.0.1. Now when I run
my program, at least on Windoze, (haven't tried Linux yet), I get an Access
Exception on the ov_open. Nothing else has changed. All I did was replace
the lib and dll files that are in the win32sdk zip and re-build all, so
it's the same the project files for for both builds.

Problem using 'ov_open()'...
OK, I've been developing a small class that I can use in virtually any
application to load and decode OGG files. Everything works fine until it
reaches the line with the call to ov_open, then the application freezes and
has to be killed. This is a single-threaded Win32 app. Below is both the
structure that gets passed around, and my entire OGG class. Maybe one of
you can figure this out.

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

Why does ov_open fail?
hello everyone.
after reading through the api manual of the ogg vorbis win32 sdk, i
tried to implement a very simple comment reader in visual c++. but for
some reason the very first operation to initialize the OggVorbis_File
struct keeps failing and i can't figure out why. is there anything i
might not have considered? The memory exception seems to happen deep
