Vorbis as a benchmark
Seeing the discussion on using vorbis as a benchmark has prompted me to post
a few results that I have. Times are as reported by oggenc.
I used track 8 on Stereolab's Dots and Loops album.
It's 334 seconds long.
Tests on windows machines used the windows oggenc binary from www.vorbis.com
Tests on unix machines used oggenc compiled on that machine.

Using large-scale repetition in audio compression
This idea is so simple that I'm sure it must have been thought of
before, and discarded, since AFAIK it's not used anywhere. I did a
quick web search but that didn't turn up much, so I figured I'd put
it up for discussion here anyway.
How about using large-scale repetition in audio compression? I'm
thinking of redundancy in repeated pieces of a song, ie a chorus.

5.1 surround channel coupling
>Yesterday I have finished writing the ambisonic pan filter for oggenc.
May I ask what this "pan filter" is?
I made some tentative suggestions for coupling Ambisonic B-format in a post
"Vorbis Ambisonic coupling" on 4feb07
I gather from the last monthly meeting, that some of you, including Monty, had problems with the phase behaviour of B-format.
Would anyone like a

5.1 surround channel coupling
It obviously would be nice to have such a mode available, for e.g. DVD audio
compression. Apparently, the list doesn''t tell me too much about it. My
questions are:
1. What is the current status of the 5.1 channel coupling in Vorbis?
2. If I''ll be interested in participation in its development, what is the
recommended reading?

[LLVMdev] Compiling issues: undefined reference to `.Lline_table_start1'
Hello LLVM,
I encountered the following bugs when I compiled my program in debug version.
Could someone help me with that ? Really appreciate that. Thanks,
Take the mcf program in SPEC2K6 as example. The compiling options are :
clang -O0 -c -emit-llvm -o obj/mcf.o -g -DSPEC_CPU mcf.c
llvm-link -o mcf.bc obj/mcf.o
opt -o mcf.opt.bc mcf.bc -O2
llc -O0 -relocation-model=static -o mcf.s

[LLVMdev] Compiling issues: undefined reference to `.Lline_table_start1'
What do you mean by test case please ? Using the following commands to compile mcf program
can reproduce such issue all the time.
Probably it is my version's problem. Because I checked out 3.3version from SVN before published.
Could you tell me where Manman modified ? I cannot port to new version very quickly after changing
it a lot already.
Thanks,

This is from work that Manman did. I thought she'd fixed this particular
issue though. Can you file a bug with a test case please?

Hi,
What version of clang are you using? I think r174785 is the fix.

Header structure for "video" stream ?
I am writing a tool that gives information on movie files (http://avicodec.duby.info/) and I want to add ogg support.
I have found full of information on ogg file format, vorbis file format, but nothing on the "video" bitstreams that I can found in some ogg files (with XVID movies mixed with vorbis audio for example).
I can see that the "video" structe looks like this, but

blank plot----how do I make symbols appear
Hi,
I am trying to create a scatterplot, coding each point to one of 5
populations. I was successful when I did this for one set of data, yet
when I try plotting other data a blank plot appears (although the axes are
labelled and I can fit the regression lines from each population). I have
tried a variety of things to fix this but nothing seems to work.
I can plot the points if I do not

Theora support in ffdshow a ffvfw
Hi,
I'm developing ffdshow and ffvfw codecs for Windows. You can read more
about them at http://cutka.szm.sk and http://sourceforge.net/projects/ffdshow.
Stéphane Bérubé asked me recently if I could implement Theora support. I knew
about first Theora release, downloaded its sources and tested it. I liked
the results add decided to support it.
