Hi all, First up, this is not a proposal on how to do it, but rather on how to get it done. In the latest thread it was mentioned that it was most likely that either Monty or Segher would be the most likely people to implement this code. It was also stated that this is not their priority at the moment. I can only see two solutions to this problem: 1. Find someone else with the knowledge and

Given all this talk of peeling lately, I thought I'd try out a method I've been thinking about for a while now. It goes something like this: * Peeling is achieved by dropping some of the residue. * The encoder indicates how much of the residue to retain (e.g a number of stages, 3 bits in the stream per packet, non-standard!). * The decoder (peeler) copies the contents of packets except

Hi all, I'm porting the Tremor code to an ARM platform. Unfortunately, we didn't use the low mem branch code for CPU performance consideration, and now I find the memory use in it is huge for the embedded system. After looking into the code, I found the header parse, especially, the codebook unpack part takes a lot of memory. Tremor decodes the codebooks to a cache to store

Hi All, As specified in earlier email we have released the trial version of the ogg vorbis decoder. Along with the decoder we have released an experimental version of the bitrate peeler that we have used to test the decoder for bitrate peeled inputs. We have made the executable of the bitrate peeler available from our website downloads section. www.vinjey.com/ogg_downloads.html

Hi all, [For the uninitiated: a "peeler" is a program that transforms a Vorbis stream into a smaller, (somewhat) lower quality Vorbis stream, and does so quickly, by just throwing out some data.] After having prototyped several peelers that aim to peel to a certain filesize, or to a certain quality, with mixed success, I've now taken a different route: a peeler that aims for the

libvorbis 1.3.6 has been released. This release fixes several vulnerabilities, including CVE-2018-5146, that could allow code execution from a specially crafted Ogg Vorbis file. * Fix CVE-2018-5146 - out-of-bounds write on codebook decoding. * Fix CVE-2017-14632 - free() on unitialized data * Fix CVE-2017-14633 - out-of-bounds read * Fix bitrate metadata parsing. * Fix out-of-bounds read in

Hi, Aditya, I took a look but I was hoping for a simpler example. And something that is more "usual". As Florian mentioned, these branches are on undefs. But thank you.

first, congrats to monty and the whole crew for getting this close to 1.0. it's a monumental achievement reflecting a huge amount of hard work -- kudos! econd, i know the bitrate peeling feature has been pushed back until after 1.0 is out. but i'm wondering -- will oggs created with a 1.0 encoder be peelable with an as-yet-unreleased utility, or do "peelable oggs" have to be

I know transcoding is a bad thing. However, i am in the need of being able to lower the quality of an ogg file without the original CD. Whats the best way to do it (least generational loss possible) - "ogg > ogg" or "ogg > wav > ogg" or is there an easier way (as in has someone got a decent working peeler up there sleeve and isn't telling anyone about it)

Dear All, As i have understood it , the Huffman codebook uses a huffman code present in the bitstream ( lets us say it is decoding a floor 1 Y value using the specifed codebook number ) to walk through the huffman code book tree till it hits a leaf node which is nothing but the entry number. If we consider our floor 1 Y value example , this entry number is directly being used as the Y value.

During the interesting interview that binaryfreedom has made with Monty and Jack, Monty mentions cascading, a feature that will be added, quote: "Cascading is the ability to make multiple passes through the frequency spectrum, iteratively filling in more detail, like a progressive jpeg". What are the advantages of something like this - does this generally improves quality or is it used
