Hi! I've spent the last few nights digging into the Vorbis source and working to implement a vorbis_synthesis_pcmout_int() function that kicks out interleaved int16_t pcm data. I think its important to have this function available to make the job for people using the codec a little easier. This function abstracts out the conversion to int16_t and removes the extra overhead of moving the pcm

I was just trying to build the shared lib stuff and include it into RC4 of FreeAmp 2.1 today, but I found that the .def file for the vorbis build stuff is missing and therefore no .lib file is generated. Is there a reason for that, or is it just an omission? In any case, I will hold off on the latest and greatest vorbis stuff in FreeAmp until next week.... --ruaok Freezerburn! All else

Hi folks, I've been dickering around again, wasting the time away.... and today Brian Zisk (chief Vorbis Evangelist among other things) said, "Hey! We need to demo to the world on the 4th of April!" Hooo boy. Time to suck it up and bang it out. The Vorbis libs are not a problem. I'm in process of checking in my new psychoacoustics (they're real pretty!) based on

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

Now that a few folks of the appropriate technical background are listening (and that a couple more I'm expecting to join in a bit can grab this message from the archive), it seems prudent to start talking about where Vorbis is and what it needs. I'll assume at this point everyone knows what Vorbis is; stop me if I'm wrong ;-) More of the code is complete than the web pages might

Hi, I am interested in helping out with the project. What tasks are on the TODO list? I am one of the lead developers of the FreeAmp (www.freeamp.org) project so obviously I will create a decoder plugin for our player but I would also like to help out with the Vorbis CODEC itself. elrod --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/

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

Hello. Not certain this post belongs here, got a little confused about vorbis-dev / vorbis. If it doesn’t, please tell me so :) Well, on to the problem. I’m adding ogg support into an audio-player. For some reason I want it using vorbisfile threw the dll’s. It works just fine with the debug dll. No problems what so ever. But with the Retail dlls, when I call ov_open my memory gets messed up.

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

Hello: I don't usually post requests like this to mailing lists, but I've just about run out of other options. The vorbis.org and vorbis.com sites both make mention of a beta vorbis output plug-in for freeamp, but I'm blowed if I can find it anywhere. It's definitely not in the vorbis.com download section (unless it's been placed their within the last 24 hours or so), and

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

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

Having not been reading the list regularly for the past few months, I've been reading through for the past few days trying to catch up. I was wondering what the current state of Vorbis metadata was. Has anything been agreed upon as far as how metadata is to be stored? It seems every time this was brought up before it turned into a large debate and nothing was ever resolved. Tony Arcieri

I've come full circle on the Ogg text stream format, back to arbitrary associated xml streams. What's changed? Mostly rolling the requirements around in my head, and weighting them differently. I think we've dealt with the complexity issue; this functionality can be optional for "dumb" audio players, and possibly also for dumb video players, though there it's a smaller

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

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

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

OK, into the nitty-gritty, albeit a high-level version. If it sounds like I'm glossing important details, you're right. This discusses only the basic DSP; precise coding, framing, sync, etc, will be in another mail. Vorbis is a hybrid transform domain general purpose audio encoder, like MPEG in some respects (it is rooted in much of the same basic theory). For the most part, the
