similar to: lack of detail for exception in 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.

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"

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 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) {

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. char*

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

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

Hey there I'm using CodeWarrior8 for development on the windows platform and have been trying for some time now to add .ogg support to my engine project. First i had the problem quite a lot had out there with a crashing/freezing call to ov_open which i solved by recompiling those libs against the single-threaded variant of the core libs using VC++ 6 But now i have another problem. now every

Hello! There is a problem with the VorbisFile library. It only works when I open an OGG file for the 1st time. After I closed the file and try to open another one or the same it crashs. It seems it applies to the use of either ov_open or ov_test functions or their combination. I wrote a test app that illustrates the bug. It crashs with a message "Unmapped memory exception". It's

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 was wondering if anyone out there had any success dynamically loading the Vorbis libraries via LoadLibrary on Win32. I'm able to use things properly by linking in the static libraries, but when I try to load them dynamically (which I really need to do), I get an access violation when calling ov_open. The code looks something like this... typedef int

Hi there. I'm having this problem when trying to open the stream to play it. What I'm doing is the following: archivo_original = fopen(Archivo.c_str(), "r"); if (archivo_original == NULL) { if (EventLog) EventLog->WriteString(Format("No se pudo abrir el archivo %s", ARRAYOFCONST((Archivo)))); WaveOut->Stop(); return; }

I've tried 3 times to drop a 250kb wav file on oggdrop, and oggdrop crashes each time. Is this too large of a file for oggdrop? -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.xiph.org/pipermail/vorbis/attachments/20060211/663a007d/attachment.html

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

Ok here is the breakdown. I am trying to impliment streaming into our game using openAL and ogg-vorbis. In the non-streaming function when I call ov_read on the file I should be streaming the buffer gets filled with the correct data. However, when I run ov_read on the same OggVorbis_File when I read the buffer gets filled with 0's. The buffer has not been zero'd and starts filled

I am getting the following error from MSVC when calling ov_open() from my app: Unhandled exception in Progname.exe (KERNEL32.DLL): 0xC0000005: Access Violation The call stack shows: KERNEL32! bff7b9a6() VORBISFILE! 00471d1d() I am running Win98 and v1.0 off the vorbis libs. The app is single- threaded. The following code works just fine in a test app I built, but when I add it to another

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

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
