similar to: vorbisfile crash on file open/init

Greetings all, I've just started playing with Vorbis to track down a problem in someone code, however I've hit apon my own problem which is stopping me, I already posted it to the standard Vorbis mailing list however I was advised by someone on there to post it here as well, so having left it ~24h since my first message I decided to mail it here as well. The application in question is

Hi, this is my first post, I hope it's the right mailing list (or should it be vorbis@xiph.org?) I just downloaded "SDK for MacOS9" and tried to compile the "vorbisfile_example.c" sample with CodeWarrior for Mac 8 on a Mac OS 9.2 machine. I included the libOgg and libVorbis libraries in my project, but the linker cannot file ov_clear(), ov_read(), ov_pcm_total(),

Hi, How can I use vorbisfile when I've already read the data into memory of an OGG file?

-----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

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

Is there a straight forward method for seeking straight to a particular logical stream using vorbisfile? I'm guessing I'll have to look the offset for a given link up in vf->offsets, and use that in ov_raw_seek?

Hi folks, I've finished a round of extension and optimization of Vorbisfile. I'm working on docs to the committed changes right now. I'd appreciate testing of new functionality and verifying old functionality isn't broken. Summary of changes: General seeking cleanup; a number of boundary cases dealing with short files and chained files got fixed in the process. The bugs should

Hi, Can anyone tell me where I can get sample C# code to call the native (win32) dll vorbisfile.dll to decode a vorbis Stream? I want the native performance of this methodology, however Ive tried porting the invocation code to C# and keep getting null reference errors when Calling ov_open_callback.

I'm seeing some inconsistency in returned timestamps using vorbisfile. I open a file, read some data (grabbing timestamps with ov_pcm_tell), then seek back with ov_pcm_seek(vf, 0) and read it again. The seek lands back on 0, but on the second read through, there's a gap in the timestamps: they jumps up by 2112 frames. This causes my vorbisfile code to insert silence to maintain sync (as

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

Hi In the vorbisfile API Overview, section 'File Information' on the Documentation page (http://www.xiph.org/ogg/vorbis/doc/vorbisfile/fileinfo.html) The 'ov_bitrate_instant' is said to return -1 if at the beginning of the bitream or no new information is available. According to the libVorbisfile Documentation, the return value is 0 in this situation. PG --- >8 ---- List

I use Borland C++ Builder 3 and I'm having trouble getting vorbisfile to work. This version of C++ Builder prefixes function names with underscores, so in the .obj file ov_open would look like _ov_open. Now, when linking the .obj files, it looks for the function _ov_open in all other .obj files and .lib files in the project. It finds none, and gives me an unresolved external error. I can

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

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

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

Good day. It seems vorbisfile has a bug. There is a such string in ov_time_seek: ogg_int64_t target=pcm_total+(seconds-time_total)*vf->vi[link].rate; It is not accounted type convertion between double and ogg_int64_t. E.g. if I convert 440267'th sample (44100Hz source) to time: double dSec = 440267 / (double) 44100; and then try to seek dSec: ov_time_seek(pOVFile, dSec); the resulting

Bug: vorbis/lib/vorbisfile.c, ov_time_tell. When vf->seekable = 0, link = -1 at the return, thus dividing by vf->vi[-1].rate.

Here's a patch to vorbisfile.c in libvorbis that splits the float to integer pcm packing out of ov_read into it's own function. The good stuff: - ov_pack_pcm can be used by folks who decode to float pcm with ov_read_float to do various sound manipulations (eg, preamp, fades, replaygain). No more need to roll your own, which will really begin to pay off when 24 bit output gets

Some months ago I tried to get some answers (and didn't) for a problem I've had with ov_pcm_total for files 8kb or smaller. I have no idea whether it should make a difference, but I operate inside Visual Studio, with C++ 6.0 and MFC. The value returned by ov_pcm_total doesn't agree with ov_read. My solution had been to add 0.2 to the buffer size, so that ov_read would make it to

Hello, All. I am making an Ogg Vorbis decoder based on Tremor. The Vorbisfile library provides a high-level API which enables us to seek in the file, but it needs to declare a pointer to OggVorbis_File structure. Because I am supposed not to use file, so I can't use the ov_pcm_seek() or ov_raw_seek() functions to seek in the file. For decoding an Ogg Vorbis file, I first put it in
