similar to: ov_open returning OV_EBADHEADER

Hi there. I have been hearing to ogg vorbis for maybe 2 years and I can only say: it is fantastic! Right now, I'm working in a project that uses ogg vorbis as the format for recording. I have now a working recording engine (I have recorded up to 8 channels at the same time and my computer uses only about 30% of the processor, wich is great in this project), and I'm starting with the

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

Hi, I've been playing with a little player, and it seems I can't ov_open a file twice? heres a snipit... <p>#include <stdio.h> #include <stdlib.h> #include <errno.h> #include <vorbis/vorbisfile.h> OggVorbis_File vf; FILE *f = NULL; int main(int argc, char **argv) { char *file = NULL; int err = 0; if(argc < 2) {

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.

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. Does anybody know if

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, does

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

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

#include <stdio.h> #include "vorbis/codec.h" #include "vorbis/vorbisfile.h" #include <io.h> #include <fcntl.h> #pragma comment(lib, "vorbisfile_d") int main(int argc, char **argv) { FILE *fp; OggVorbis_File obf; if(argc < 1) return -1; if((fp = fopen("f:\\testogg.ogg", "rb")) == NULL) { printf("Open Files

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. Here the snippet of code that

If I do something similar to the below ov_open always causes an access violation. The call to fopen is successful. Can anybody tell me why? (and how to fix it?) OggVorbis_File vf; int eof=0; int current_section; FILE *fd = fopen("c:\\test.ogg","rb"); if (!fd){ AfxTrace("fopen failed\n"); exit(0); } if(ov_open(fd, &vf, NULL, 0) < 0) {

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

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 within the calling tree of

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

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 greetings, Sebastian ---------- <p><p>Hi! my code causes access-violations in ov_open. I'm using MS VisualC++ 6 SP5 on WinXPpro with oggvorbis

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: #include "vorbis/codec.h" #include "vorbis/vorbisfile.h"

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

there can be a minor bug in vorbisfile: when opening an invalid file with ov_file the errorcode is returned as it should, but the OggVorbis_File struct can't load another file: using ov_open on the same struct with another file segfaults. also using ov_clear on the struct before reopening does'nt helps. workaround: delete and recreate new the OggVorbis_File for each opened file. --

Hey, i'm having trouble getting ov_open to work on my slackware 8.1 system. The c, and makefile are as follows, and the error produced. I've also included an ldd of the compiled file. If anyone can be of any help, it would be greatly appreciated! --------------------------C FILE------------------------------- #include <stdio.h> #include <string.h> #include

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. If I pass fopen a
