Fixing ogg vorbis corruption caused by bad metadata
Can I fix the checksum with a hex editor?

The second page is corrupt. The basic structure looks correct, first
guess would be bad checksum. I'll look more closely in just a bit.
This might explain why some players might accept it--- if

Stream Test
Hi
Seeing as other people are posting streams to test, the system I have been
developing has an Ogg/Vorbis/Theora stream that you can watch. I would
appreciate any feedback to what players can play it and which players have
problems. (I am using Icecast as the streaming server)
So far I have found VideoLan plays the stream very well. MPlayer was ok,
but wasn't as good at buffering.

Webm files written without duration in header
Hi there
Thanks Thomas. I was hoping to avoid remuxing as my objective is to run an
extremely lightweight server. Just tested and the CPU runs between 9% and
23% for a lecture of 90 minutes - took 18sec. Yes it's a lightweight
server, but like I said, that's the objective, and quite a nice challenge
:-) CPU = cost and if you have to remux for 1000 clients in a day,

New Ogg Dirac mapping draft
David Flynn has proposed a new Ogg Dirac mapping. The draft is here:
http://davidf.woaf.net/dirac-mapping-ogg.pdf
This is a much bigger break from other codecs than my draft (at
http://wiki.xiph.org/index.php/OggDirac). We talked a bit about it on
IRC today. Below is my summary; hopefully David can correct anything
I got wrong or misleading. Comments?
There are two main differences

Multi-channel labels in Vorbis comments
Hi devs :-)
At the Mozilla Festival in London recently, I took part in a Hack the DJ
workshop, looking at ways to take digital DJ'ing to the next level:
http://www.bbc.co.uk/blogs/researchanddevelopment/2011/11/setting-a-dj-challenge-at-the.shtml
One of the ideas proposed was stem mixing, using multichannel files in
DJ applications. A proprietary implementation of this idea is Fireplayer

ogg dirac granulepos in oggz tools
Hi,
I'm wondering if the Dirac granulepos parsing in liboggz and display
in the oggz tools is currently correct, as I'd like to do a release of
these soon.
A couple of days ago David Schleef mentioned there were some problems.
David, is that currently true (ie. since David Flynn's recent updates
to support Dirac), and if so could you please explain what the
problems are, or point me

Page breaks when encoding ogg/theora
Hi everyone,
I'm trying to build theora encoding into my game engine. Essentially,
I'd like to do something similar to png2theora.c, where I take
individual screen shots of my game and encode them into a video.
Because png2theora.c uses the legacy C API, I used encoder_example.c
as a template instead. encoder_example.c seems to be the only code out
there that actually uses the th_* API.

ogg_stream_flush
Hi,
While building an ogg-vorbis stream encoder, I encountered some problems
with silence in the audiostream.
The bitrate drops to almost zero, and pages going out less then ones a
minute what makes the stream to stop / buffer.
In earlier postings I read that I shout use ogg_stream_flush as an
alternative to ogg_stream_pageout, in case of silence.
My question is this; Is there any

great, thanks :-)

Problems seeking with liboggz
Hi,
I intend to use Ogg+Speex for voice recording/playback in a VoIP app.
I am experimenting with liboggz to get acquainted with its API.
As test files I am using some Ogg-Speex files converted from WAV files
with speexenc.exe.
I wrote a little testing app in Visual Studio 2010 under Windows 7.
I defined OggzReadPage and OggzReadPacket callbacks with
oggz_set_read_page()

Problems seeking with liboggz
Hi,
The Ogg-Speex test file I used is CBR. I am sure of that by running oggz-dump on the file and confirming that all audio packets have 38 bytes; that means (for narrowband) a constant 15 Kbps.
I wrote a very basic test program in Visual Studio 2010 that demonstrates the strange behaviour I mentioned.
The output shows that the audio file has 8 pages, 6 of them

Fixing ogg vorbis corruption caused by bad metadata

I just realized that the hogg tools will fix the CRC issues (by design
accident: hogg ignores the CRC on reading but sets it correctly on
writing). "hogg rip" rewrites the pages (fixing the CRC), and "hogg
reconstruct" also rewrites the

Cover art
Hello to the people reading this list!
I am developing tagging support for ogg vorbis in Nero products and we are
currently thinking of supporting cover art in ogg files. What is the current
state of proposal for cover art in ogg files? Is this
