similar to: Loading a dll from another dll

Hello. Not certain this post belongs here, got a little confused about vorbis-dev / vorbis. If it doesn’t, please tell me so :) Well, on to the problem. I’m adding ogg support into an audio-player. For some reason I want it using vorbisfile threw the dll’s. It works just fine with the debug dll. No problems what so ever. But with the Retail dlls, when I call ov_open my memory gets messed up.

Hi, I've ditched the idea of calling the oggvorbis .dlls, and I'm compiling the 1.0beta3 source into my own dll. After opening as "rb" instead of "r", the ov_open() call works. However, ov_read() seems to consistently read less data than I ask for. My buffer is enough to hold two seconds of data, 16 bit 44k mono, that's 176400 bytes. The first call to ov_read()

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

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

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

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

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"

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

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) {

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

Should I ov_clear a failed ov_open/test/test_open call? The xmms plugin does an fclose on failure, and that seems to work, but I thought I ought to know for certain. (An observation: I think the quantity of questions and bugs raised along the lines of "I did open file, ov_open, ov_read, close file, open another file, ov_read, and it exploded", or "I tried to make vorbisfile go

I've been playing around with using ov_test and ov_test_open as an alternative to ov_open in the xmms plugin's vorbis_check_file function. xmms never bothers to cache the result of a file check, so it tends to happen rather a lot. Unfortunately ov_test_open returns OV_EINVAL because ov_test seems to have left vf->ready_state to OPEN rather than PARTOPEN. I'm presuming this is

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

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

Hello, I'm currently trying to implement streaming off ogg-files out of an archive file using SDL and SDL_mixer for playback. Therefore i create a FILE * filepointer, place it to the beginning of an ogg file inside the archive and hand over the filepointer to ov_open. ( command: ov_open(fp, &music->vf, NULL, 0) ). This works fine so far. The problem is: if i put many oggs together in

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 have a problem i suspect to be a bug in ogg: Assume i have a simple archive "chou_s_test1_test2.pak", created by simply concatenating binary files together: chou_s.jpg (3403 bytes) test1.ogg (5196 bytes) test2.ogg (6128 bytes) If i place the a filepointer passed to ov_open to the beginning of test1.ogg, this ogg gets opened and decoded correctly. But if i place it to the beginning

this it is the first time that I program with ogg libraries (I am a beginner). it has happened me an error, the code is the following one: /*********************************************/ OggVorbis_File *musica=NULL; FILE *archiv =NULL; archiv = fopen("prueba.ogg","r"); if(archiv==NULL) exit(0); int falla = ov_open(archiv,musica,NULL,0);//aca se produce el error

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
