similar to: Fw: ov_open failing with all files

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 am using libvorbis-1.0.1 and I am trying to debug the example decoder (examples/decoder_example.c) using gdb. I have compiled the source tree for debug and can single step through the program. However i am facing the following problem (which I think is more of C than vorbis) 1. after single steppig I finally arrive at the function shown below (in file lib/info.c) static int

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 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 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

I am struck here. What magic inchantation is required with tkmenubutton? I am converting the examples of Perl/Tk from page... http://gd.tuwien.ac.at/languages/perl/Hajji-Perlkurs/part4/tkperl.html ... to R's tcltk. But I don't know how to convert one line in this example: library(tcltk) # create a main window mw <- tktoplevel() # a menu consists of a horizontal menubar, # with

Hello everybody, I sent something about this before, but this bug is still there, so... If you call ov_time_seek(vf, 0); it will fail, returning OV_EFAULT (from ov_pcm_seek_page). I think this must be a bug, because seeking to 0 seconds *should* be OK. Another thing, when ov_time_seek fails with OV_EFAULT, you cannot continue playing (because of the goto seek_error). This is not clear from

Dear members, since two weeks I am stuck, trying to demux a physical ogg stream (theora and vorbis) and play the audio part using vorbisfile. I hope that one of you can give me a hint or point me to additional documentation. I used ogg.h and vorbisfile.h. The way so far: - initializing an ogg_sync_state - inserting data to sync_state using ogg_sync_buffer - when whole page found

Hey all, If my understanding is right, there's a serious big in vorbisfile.c, in the routine _fetch_headers(), which will only show up when comment packet spans multiple pages. The code to read the first 3 Vorbis packets ogg_stream_pagein() once, then calls ogg_stream_packetout(). The problem is that ogg_stream_pagein() only adds a single page to the ogg stream state, whereas

Hi! I'm trying to write a vorbis plugin for my MP3/Music/Media player (http://elmp-tng.sourceforge.net). I'm using vorbisfile, and ov_open_callbacks() (to interface with my VFS layer). The problem is the same using plain ov_open() though... Some files play perfectly, while others (most) fail. ov_open returns OV_EBADHEADER. The really strange thing is that both ogg123, and the simple test

Hi. I'm trying to implement Ogg/Vorbis support for the MPEG4IP project. The goal is to support Ogg/Vorbis audio for MPEG-4 streaming. So far I have managed to make the encoder save Ogg packets as an Audio object in an .mp4 file. As a side effect, it can also save Ogg pages in an .ogg file playable by xmms, but that's no big deal. So what I'm doing is this. First the init part. a)

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

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

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 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
