Hello! I just got _very_ scared. I was certain the Ogg libraries could be used in commercial products (I know they are used in Star Trek: Away Team and Operation Flashpoint). I've also been told several times that it's OK, even if they're not GPL, but now I can't find any info on the sites that tells me so. Could you please tell me what the deal is (I've used it in a project

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

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 all, While reading through various bits of libvorbis and vorbisfile, and then thinking about how to implement other features in the xmms and winamp plugins, I had some thoughts... Vorbisfile is very useful, and very easy to use. It is, however, tied to stdio - which means you can't use it for lots of other stuff where it'd be useful - like streaming, or (under win32) avoiding stdio

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

Hi, I use the following code: if (ov_open(NULL, &vf, const_cast<char*>(reinterpret_cast<const char*>(get_data())), get_size()) < 0) error = 0x100; else { vorbis_info* vi = ov_info(&vf, -1); Cvirtual_file f; const int cb_samples = ov_pcm_total(&vf, -1); const bool seekable = ov_seekable(&vf); So all data is already in memory and passed to

Just noticed this article on Slashdot: http://ask.slashdot.org/article.pl?sid=04/05/18/0432202 ...about the feasibility and efficiency of reading id3v2 tags out of mp3's over http. I know that vorbisfile's callback model is well suited to handling this sort of scenario, but I'm curious to know whether ov_open will try to read enough stream to pull the comments out on a

OK, I have a minor problem with the 'vorbisfile' libraries. I copied both the normal and dynamic DLLs to my program directory, and they load fine. Thing is, if I link with 'vorbisfile.lib' and use 'ov_open', the application just locks up. If I link with 'vorbisfile_d.lib' and use the function, Windows brings up a standard crash window, and I can just use that to

Hello, All. First, I want to thank Ian Malone and Ralph Giles, thanks for your kind replies. But I still have problems about seek. As you suggested, I could use ov_open_callbacks() to supply my own read/write/seek functions. So, can you give me an example? I?m sorry for my ignorance, because I haven?t used callbacks before. I analyzed the vorbisfile.c in Tremor, and I think I

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"

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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I'm writing a simple application to decompress a set of Ogg files to raw PCM format, using vorbisfile, because that is the simplest way of doing it. These Ogg files are sounds for a game, and thus sometimes very short (about .25 s). However, vorbisfile has severe problems with Ogg files that are smaller than the CHUNKSIZE which is #defined

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

Hi, I've been tinkering with vorbis for about a week now trying to get the vorbisfile lib to compile under win32s, I was wondering if someone could give me a hand as I've reached my wits end with it ... I recieve the same message for every bat file (after customizing it for my path configuration): *F:\src\vorbis\win32>build_vorbisfile_dynamic *---+++--- Building Vorbisfile (Dynamic)

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

The changes to vorbisfile that I suggested earlier have now been committed - this is mostly a merge of my code with a similar patch from Martin Vogt (thanks Martin). The old ov_open() interface remains untouched - and for many people, this is all you'll need to use, ever. It now calls the new interface with appropriate arguments. The new ov_open_callbacks() function adds an extra argument to

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

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
