Vorbis primitive API examples (LONG)
Okay, how do I drop a changeset/patchset/tag for you folks from SVN?
At this point, I have written three examples of how to use the basics of
the ogg streaming and decoding in Tremor. I heartily welcome any
suggestions, improvements and corrections that you can point out in the
code.
The examples required me to make some small modifications to the main
tremor library. However, the changes

Stream "Saving" and Excerpting...
I'm working with a streaming Ogg Vorbis system where I'm taking the stream
output (from a darkice server) and saving it to hour-long files, then
reassembling excerpts from these files (sometimes spanning two or three)
into a single file for playback.
I've got two problems (well, related to this, but anyway).
1) The "chunk" files I'm saving into have mangled headers.

Crash when reading OGG/Vorbis file
I'm seeing a crash when reading an OGG/Vorbis file. I'm using OGG 1.0
/ Vorbis 1.0.
The crash occurs in _vds_shared_init because the passed in vorbis_info
*vi points to a structure containing all 0s (and thus crashes on the
line
b->modebits = ilog2(ci->modes);
as ci is NULL.
Following the stack, I see that _vds_shared_init is called by
vorbis_synthesis_init which is called

speex affected by vulnerability described in [oCERT 2008-02]
Hi folks,
we've tried contacting Jean-Marc Valin but email address bounces. We
published yesterday an advisory about libfishsound, you can find it at the
following URL:
http://www.ocert.org/advisories/ocert-2008-2.html
The issues seems to affect Speex (since the code is the same) versions <=
1.1.12. While the 1.2beta branch is not vulnerable we advise that you fix
with a security release

Simple example of decoding streaming audio realtime?
Conrad,
That's exactly what I was looking for. I just got finish trying several attempts at porting libfishsound to XCode/CocoaTouch land but am facing dependency issues on the other xiph libraries. (liboggz, libvorbis, libflac, etc.) Rest assured I know what the issues are and how to address them. I am at a fork here. I can either port the bulk of the xiph libraries to XCode or continue on

Simple example of decoding streaming audio realtime?
Hi,
I'm new to Speex and a little uncomfortable in C programming. I'm looking for a simple example of how I'd use Speex to decode a speex file read off of an network stream and pass the decoded samples to an audio player. I have speex running in an iPhone project and I started digging thru the speexdec.c example trying to refactor as I made sense of the API calls. The example is a

[libfishsound ] Using static libraries instead of DLLs
Dear,
I'm sorry if this is not the correct list to post a question about
libfishsound but I don't have found a specific one.
I'm writing a library that use libfishsound for encode/decode speex and
vorbis streams.
I would like to incorporate all the functionalities into my static
library without any dependencies on extern DLL.
Is there a way to compile libfishsound using ogg, oggz,

I have a problem. I've started to develop crossplatform sound

receiving packages and when I write them to file application example
from libfishsound is properly decoding it. Problem starts, when I want

No. Speex expects values in the +-32767 range, not +-1.0. Just
converting from int16 to float *is* the right thing to do.

When I load the codec as an Audio Codec the call to AudioCodecInitialize appears to work but if I then get the IsInitialized property that says it is not initialized - so looks like that is my problem, and ties up with the crash in vorbis_synthesis_start(). Looks like vorbis_synthesis_init() has not been called, perhaps.
There's sample code out there that suggests people have got this

liboggplay, liboggz, libfishsound migrated to git.xiph.org
Hi,
A week or two ago Viktor Gal migrated the liboggplay source repo to
git.xiph.org, and this week I moved the liboggz and libfishsound
repositories.
You can see the git repositories available via gitweb at http://git.xiph.org/
I wrote some brief news about the move, and instructions for getting the code:

Streaming API?
I'm new to Speex and was wondering if there is a nice streaming API similar
to Vorbis' "ov_open_callbacks", "ov_read", "ov_time_tell", etc.
If not, is there an easy way to get Speex streaming from files?
My appologies if this has already been answered a million times, but the
archives aren't currently accessable!
Thanks,

Tutorial/Docs for using libvorbis directly
Hi,
We needed a vorbis decoder that operated differently from the approach taken
libvorbisfile. So I sat down, looked through the docs, and the sample decoder
that come with libvorbis and wrote our own.
Since I couldn't find any docs for the API for libvorbis itself, I've written
some. It details all the steps you need to go through to write a _basic_
reusable decoder library using

Ah, OK, I understand where you're headed now.
