Hello, It seems there is an error in the algorithm for floor0 decode in section 6.2.2 of the Vorbis specification. Here's the relevant part: 3 3) [coefficients] is an empty, zero length vector 4 4) [booknumber] = read an unsigned integer of ilog( [floor0_number_of_books] ) bits 5 5) if ( [booknumber] is greater than the highest number decode codebook ) then

Hi, I need another clarification regarding the standard. In floor0 header decode (setup), the point no.7 says that if any of [floor0_order], [floor0_rate], [floor0_bark_map_size], floor0_amplitude_bits], [floor0_amplitude_offset] or [floor0_number_of_books] are less than zero, the stream is not decodable But as we see, all those values are read as unsigned integers. Now I'm not able to

Hi ! <p>I previously posted a mail in the vorbis-dev mailing list because I'm trying to implement a vorbis decoder in java from scratch in my sparetime and have some questions about the bitstream spec. As I did not get any replies, I got kinda dissapointed and demotivated - But now.... I'm trying to take my chances here. :-) I'm NOT a newbie to source coding (I successfully

Do anybody know, from where I can get an Ogg Vorbis File, which uses floor0 coding. I know that the current encoder doesn't use floor0. Anyway, to be fully compliant with the Vorbis Specification the decoder still must be able to decode floor0. I am working on a Vorbis port to a DSP. I want to go sure, that if the need of floor0 decoding will again occur, this also will work properly.

Hello, everybody. I am looking for same Ogg Vorbis file which have 8192 size frame or using floor0. According to the Ogg Vorbis spec, the maximum frame size is 8192. But I cannot find that size of frame in the Ogg Vorbis file. Also I cannot find Ogg Vorbis file using floor0. If you have, pleas open them. Or can you tell me where I can find them? Sincerely.

Hi All, I am planning to implement Ogg Vorbis Decoder on a 24 bit DSP. I have following doubts: 1) What is min and max bitrate? 2)What is max Audio Packet size ? 3)What is the max size of setup header? 4)Any idea how to start for making a 24Bit fixed point reference code? Shall I start with floating point or Tremor or Tremor Low Mem Version? 5) What window sizes in Ogg Vorbis are normally

Hello I'm working on a fix-point decoder for AOS/Bluebottle - the proprietary OS of ETH Zurich. I've some problems with Floor0-curve-computation: I don't know what the little omega [cos(w)] stands for, line 3 of the official Vorbis documentation. Does anybody knows what this value means? I've tried to get the answer from the jOrbis and Tremor, but both seem to do - among

I'm working on getting the Darwin/Mac OS X port of Vorbis up and running again and have run into problems building libvorbisfile. I have installed the latest libtool (1.3.5) and modified it to handle Darwin/Mac OS X better (to create shared libraries, dylibs, that can be linked against other dylibs instead of creating bundles which cannot be used as input to the linker). But, when it tries

Hi, In the course of some work which I describe below, I have found a very significant difference between the BARK function described in the Vorbis specification and its implementation in libvorbis. In the specificationhttp://xiph.org/vorbis/doc/Vorbis_I_spec.pdf bark(x) = 13.1arctan(.00074x) + 2.24arctan(.0000000185x**2 + .0001x) In the libvorbis code

Is there a archive with a collection of different .ogg files encoded with different settings that can be used to verify compatibility? * Different window size (e.g. != 256,2048) * Much larger codebooks and other extreme cases that are not generated using a standard encoder. * floor0 Regards -- / Johannes Sandvall --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project

Hi, Am trying to run beta4 encoder on a Sun machine. Want to compare floor0 and floor1. Do not have autoconf and automake. Got the encoder to compile with a simple makefile. The only define i am using is NO_FLOAT_MATH_LIB. The encoded file when played(winamp) gives out plain noise. Am i missing any other flags/defs? -Cathy <p>--------------------------------- Do you Yahoo!? Yahoo!

Hi all, I'm busy doing optimizations for vorbis. Don't have time for it, but still doing it :-) Some suggestions: there are some double function names: forward/inverse pack/unpack look/free_look/free_info and maybe more. If they were renamed to time0_forward etc. profiling would be a lot easier. Oh, and add -fno-inline to $PROFILE in the Makefiles (or configure). Most expensive

Hi Guys, I want to compile libvorbis, but I get this error message if I made a make.

First my environment MinGW and MYSYS with gcc 3.4.2 under Windows XP pro. I configured and built libbogg with out a problem. I configured libvorbis and it finds libogg.

Hi guys, I'm trying to compile vorbis-tools with libvorbis-aotuvb5. The problem is that installed libvorbis conflicts with myself-compiled libvorbis-aotuvb5, though I specified --with-vorbis-libraries and --with-vorbis-includes to the vorbis-tools configure: vorbis-tools-1.1.1# CFLAGS="-static" ./configure

The upstream NBD protocol recently clarified that servers can advertise block size limitations to clients that ask with NBD_OPT_GO (although we're still a ways off from implementing that in nbdkit); and that in the absence of that, then clients should agree on limits using out-of-band information or stick to sane defaults (everything 512-byte-aligned, no reads or writes larger than 32M). But
