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"
#include <stdio.h>
#include <memory.h>
void main(void)
{
// Attempt to open the file
FILE *pFile = NULL;
pFile = fopen("C:\\IronDaimen.ogg","rb");
if (!pFile)
return;
OggVorbis_File ovFile;
memset(&ovFile,0,sizeof(ovFile));
int iRetval = 0;
iRetval = ov_open(pFile,&ovFile,NULL,0);
if (iRetval != 0)
{
fclose(pFile);
return;
}
}
I link against the ogg/vorbis DLLs (tried both debug and release ones).
This is really very frustrating... I tried several other files, but all crash.
WinAmp plays them correctly, so it's not with the files I suppose...
Any help is much appreciated,
Wessam Bahnassi

Sorry I can't give you any more specific advice - hopefully one of the windows developers on the list will be able to (I don't use windows regularly myself, and you didn't give any details about what development tools you're using).

I'll subscribe there and give it a try, thanks... Just for the record, I'm using Visual Studio.Net 2003. My app uses Multithreaded DLL linkage to CRT.

I had the same problem because my app uses Multithread DLL linkage too. To resolve it i had to download the sources of the SDK and generate it with the right linkage settings. -----Message d'origine----- De : Wessam Bahnassi [mailto:wbahnassi@inframez.com] Envoy? : lundi 4 avril 2005 07:46 ? : vorbis@xiph.org Objet : RE: [Vorbis] Direct crash on ov_open I'll subscribe there and give it a try, thanks...
