Re: RFC3533
Hi John,
I'm forwarding this email to the relevant developer lists at Xiph.Org,
where the format was created and where the experts gather.
I'm certain there is a design reason for putting the bos pages of all
logical bitstreams together at the start. My guess is that with digital
media you usually have a delay time for setting up the decoders for a
specific format and by clustering

Ogg and Vorbis questions
>From the top of vorbisfile.c:
/* A 'chained bitstream' is a Vorbis bitstream that contains more than
one logical bitstream arranged end to end (the only form of Ogg
multiplexing allowed in a Vorbis bitstream; grouping [parallel
multiplexing] is not allowed in Vorbis) */

OggPCM version / header finalization
Hi John, all,
I still have at least 3 issues:
1) What are we trying to achieve with the "source-ID"?
8 [uint] Source ID (Unique amongst all OggPCM streams in the physical stream)
Are we trying to separate the different channels that may be interleaved with each other inside the flat multi-channel sample stream?
Interpretation 1:

So, would each channel be in a

.NET tagging library for ogg Vorbis
Hello,
I've mainly finished the native ogg Vorbis tagging .NET library. It already works well for reading and writing the vorbis comments for the files I tested. The library only rewrites the entire file if it has to, and adds 2 K padding in this case so that further changes of the comments won't make it nescessary to rewrite the whole file again. I found out foobar2000 also does it this

page syncing and magic OggS
I may be missing something, but is there a good way
of finding the start position of an ogg page in a bitstream?
Pages have to start with 'OggS', but this could also turn
up elsewhere in the bitstream, so is there a simple strategy
using the libogg API to find out which ones are the start of
pages? (Other than trying to decode from successive
'OggS' markers and noting when the

Vorbis bistream definition / separation from ogg
Hi,
I have some questions:
1) in the sources of the encoder_example (and of course in oggenc.c,
too) I see a lot of dependance
on ogg. I want to get totally rid of ogg and use the vorbis bitstream
alone.
From this reason stems the second question:
2) is there a definition of the vorbis bitstream somewhere? I don't need
to know every single
detail, just the informations necessary to

Final Ogg 1.0 submission to IETF
Hi all,
just letting you know that I am about to submit the final version of the
Ogg 1.0 file format Internet-Draft to the IETF. It is due by today
(March 3, Monday - Internet Draft final submission cut-off at 09:00 ET)
for the next IETF meeting and I expect they will promote it to RFC
status at the meeting. Please send any last-minute changes to me.
Cheers,

bitstream versioning
as per yesterday's discussion at #theora --
It has been suggested that we devise a method such that we will be able to add certain features to the bitstream (interlace, exotic color subsampling, clip length flag for download, etc), in such a way as to not obsolete streams encoded previously. Rillian's suggestion, which is pretty much standard practice, is to add a bitstream revision

eos on continued page
Hi,
I'm working on a new ogg file chopper (porting 'hogg chop' to C).
These work pagewise, ie. they just copy the pages that are needed from
the input to the output bitstream.
I'm modifying the last page in the output bitstream so that it has the
eos flag set. The last page is always one that has a granulepos set
(that of the last packet finishing on that page). But let's say

theora release todos
Hi,
last week's thread about getting closer to a release fizzled out.
The mailing list discussion and the TheoraTodo wiki item suggest the
following are required for release:
1. freeze the theora logical bitstream format
2. complete the reference implementation tools
3. stablize the libtheora API
4. complete the documentation
I'd like to suggest this as

Multiplexing problems
Hi all,
Does someone have a simple example of encoding (intializing and
multiplexing) an OGG and non-OGG logical stream?
I have successfully managed to do this to some extent. During the
playback I am able to identify the change in sections from the second
stream. However I am unable to retrieve the data as only one logical
stream is being found by the API and subsequently fails out on

ASan port for Myriad RTEMS
Hi Walter,
I've done a first quick scan.
Overall looks reasonable, but I'd like to try reducing the number of newly
introduced platform-specific ifs.
Vitaly, please also take a look (once my initial comments are addressed).
One outstanding issue is your problem with initialization vs checking,
which requires you to insert so many ifs.
Is there any chance you can avoid this?

ASan port for Myriad RTEMS
Hey,
I work on fuchsia symbolizer stuff. I don't know if you guys already have
an external symbolizer but I'm working on making one right now and I plan
on making one backed by LLVM that can be run host-side or target-side. I'd
like to contribute that back to llvm ideally. What do you guys have so far?
I have a prototype in golang that just spins up an instance of

ASan port for Myriad RTEMS
Hi Jake. Thanks for the info. Where can I keep up to date on the
symbolizer status?
Our symbolizer is provided by the Myriad vendor and integrated into its
host test environment. It doesn't do much: just look for PC string
patterns and symbolize them using addr2line.
Thanks,
Walter
