similar to: ov_clear(&vorbis) segfaults? (Backtrace and test case)

Hello all. I'm new to this list. I'm also new to coding with libvorbis and things, so please bear with me. :) I've been having trouble with libvorbisfile. My use of it is fairly simple, but when I try to ov_clear the vorbis file, it segfaults. I can attach or otherwise make availible some demo source code, but for now I'll just pull out relevant lines: //BEGIN PSEUDO CODE

I get an access violation when calling ov_clear(). I know ov_open() worked because I used ov_info to get the sampling rate and number of channels in the .ogg file. I also know the FILE pointer and the OggVorbis_File structure are still in scope (they're member variables of the same class my deconstructor is in (where ov_clear() is called)). Anyone have any ideas? I opened the file using

Hi All, Im having troubles with ov_clear crashing or just failing to close properly. Is there anything else i should make sure im doing before i call ov_clear. My code basically consists of one ogg file running completley in its own thread where it decodes into direct sound buffers. I only run 2 threads at anyone time, and ive also noticed its only the threads that use ogg files with multiple

Hi guys, I'm working doing the Java->JNI->OggVorbis thing. As a test to get me going, I've just written a quick routine that dumps info about the file test.ogg in the current directory. The problem arises when I call ov_clear. I get a segfault everytime. Note that I am *not* doing any decoding (ov_read) at all, just ov_comment and ov_info. Should I only call ov_clear if I have

I am having no luck at all mixing libvorbisfile with the cross-platform gaming library SDL. It seems that any time I call ov_clear, the app goes unstable and crashes later in calls to glibc. This is unacceptable for obvious reasons and I was wondering if there was a way to fix it by just using libvorbis. I was going to experiment with the possibility, but I have, as yet, been unable to find

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) {

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. As

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

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.

The following block of code produces an exception. The testnew.ogg file is 10 seconds, containing pure silence encoded using mode E: http://www.cs.mun.ca/~chris3/testnew.ogg Other files and modes can cause the exception, but many files work fine. #include <stdio.h> #include "vorbis/vorbisfile.h" int main() { OggVorbis_File ov, ov2; FILE *f, *f2; f

Hi, I downloaded afew off files from the site (www.vorbis.com) and also downloaded the winamp plugin (dll file), but I am unable to play the off files. -- Ramakrishnan.M | Phone : (+91-80)-5099132 DSP Applications Group, Texas Instruments | email : rkrishnan@ti.com Bangalore, India | rkrishnan_m@yahoo.com ---

The following block in os.h needs to be changed for vorbis to work under Borland: Original: #ifndef __GNUC__ #ifdef _WIN32 # define alloca(x) (_alloca(x)) # define rint(x) (floor((x)+0.5)) #endif #endif New: #ifndef __GNUC__ #ifdef _WIN32 # ifdef __BORLANDC__ # include <malloc.h> # else # define alloca(x) (_alloca(x)) # endif # define rint(x) (floor((x)+0.5)) #endif

I wonder if anyone would have a comment on an experiment I have pretty much completed in my MFC/C++ project. With my simple libvorbis implementation, ogg decoding works just fine for files that are 10kb or larger. For anything smaller (actually, I don't have a 9kb file, so <= 8), it seems that I get an inaccurate value for ov_pcm_total. Though ov_read returns zero, I overflow the buffer

The folowing code donst work: #include <vorbis/codec.h> #include <vorbis/vorbisfile.h> #include <stdlib.h> #include <stdio.h> int main() { FILE *stdfile; OggVorbis_File vf; int tmp; stdfile=fopen("./test.ogg","r"); if( ov_test(stdfile, &vf, NULL, 0) ==0) { tmp = ov_test_open(&vf);

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

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 have been working on a game for a while now and noticed that using your library to stream music created a graphical problem while the screen would scroll. (certain tiles would flicker to be more specific). I found that if I don't play music this problem doesn't occur. Another developer suggested that if I can lower the priority (thread priority) of the music this could fix the problem.

I am trying to insert a bit of ogg vorbis decoding into my MFC/C++ program and send it to my waveOut functions. // AudioFile.cpp #include "vorbis/codec.h" #include "vorbis/vorbisfile.h" . . . OggVorbis_File vf; FILE* pFile; pFile = fopen("verdes_2.ogg", "rb"); int err = err = ov_open(pFile, &vf, NULL, 0); . . . ov_clear(&vf); In my

I'm not a Win32 developer (no Win boxes right here), and debugging style mails are generally not best sent directly to me as I'm currently sporting a 2000 message backlog in my inbox. I've taken the liberty of forwarding this the the development list. On Sat, Sep 08, 2001 at 05:14:41PM +0200, Nikolaus Brennig wrote: > Hello! > > Today i wanted to implement ogg vorbis

In res0.c, line 78 I get a a division by zero (look->frames==0) when running vorbisfile_example. Is this some debugging code? Note that you don't see the exception unless you insert __asm{ push edx sub esp, 4 fstcw [esp] mov dx, [esp] and dx, 0xFFFE mov [esp], dx fldcw [esp] add
