Since 'bitrate peeling' is already supported, I believe it would be possible to transmit the 'peeled' stream and

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

Greetings, With all the press concerning the 'almost 1.0' release of vorbis; I see a lot of messages floating around as 'now 1.0, and -soon- it will include joint-stereo, Wavelets, low-bitrate, peeling, etc. etc.' Before I start 'advocating' vorbis and tell everybody what it all can do; is there actually a date or some other planning when all those

Hi: A friend asked me a question that I was unable to answer, so I'm posting it here. Can files created by the beta4 encoder be peeled down when that becomes available, or is the ability to encode peelable files also not implemented? My friend wants to know if they should switch over now or hold off until this becomes possible. Geoff. --- >8 ---- List archives:

Hi: Have been testing the latest winamp plugins on my icecast2 stream (http://bumpy.braille.uwo.ca:9000/test.ogg <plug plug>) and I noticed that in the field where the player/browser is listed in the log entries I see Mozilla for the winamp plugin. Isn't this ummmm. wrong? Geoff. --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage:

Hi! What kind of services, which use Ogg Vorbis or create value to Ogg Vorbis-user, you are interested? I'm a student at Helsinki School of Economics and Business Administration, and I'm taking a course in which we are supposed to create business plan for some new business. So, I happened to bump to Ogg Vorbis in the Intenet, and I Thought, Wow that's a really interesting product

I was up late last night, and i had a thought on peeling that would probably provide 100% accurate peeling data to a decoder, but take a maximum of 1101 times normal time to encode (taking into account the range from q-1 to q10 ). ay you want to encode a track at q10, but you want it to be peelable. the 1101 encoder would encode from the source at every quantifiable level (since there are 2

No offense, Segher, but the output quality of this thing is awful. =) I'll disregard the fact that, at least with *my* compiler, the source tarball I downloaded reduces every packet to zero bytes, which isn't terribly interesting. I decided to set the byte reduction to something constant: I started by dividing each packet's size by 2 just to see what would happen. The resulting ogg

Hello, I've been postponing some of my encoding for when joint stereo gets implemented. The reason I've been doing this, is that I am under the impression this is the largest step in the quality/bitrate ratio that's left. Now I'm wondering if I am correct in thinking this. lame's documentation seems to imply it doesn't make much of a difference at higher than 128kbps (I

Hi all, I recently started to study the Ogg Vorbis codec and found an interesting feature called bitrate peeling [1]. Do you know where I can find more information on this topic? E.g., how is the actual peeling being implemented, what are the performance results in terms of resulting quality, what are the requirements for bitrate peeling (can it be applied to any ogg vorbis stream), ...? Also,

Hello all, Just a quick note to let you all know that I have placed a bounty on Lauchpad to get bitrate peeling added to Vorbis. It is a feature that I think we would all like to have, and would probably pay something to get, but it hasn't been done. My request to you is to add to the bounty. I have seeded it with US$20, which is not enough to motivate a developer to get it done, but I am a

Icecast / Vorbis community, I have a icecast/ices audio streaming server from which I stream ogg audio files. I know that I can encode different streams for low, medium and /or high quality broadcasts (for example). However, I would like to have one stream that uses bit rate peeling to send the user the highest quality stream that their bandwidth will allow. Has any one done this? Does any

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

With the newly released SVC (Scalable Video Coding) of H264 I was wondering if Ogg/Theora has any plans of following suit or are there plans to implement a better solution? the closest to SVC I have seen at Xiph is bitrate peeling but that never happened and to date does not seem to be in any TODO list. thanks, -------------- next part -------------- An HTML attachment was scrubbed...

I'm trying to get a bitrate scaled live ogg stream working, but I've not found out how to get this running with the current tools. I've downloaded the CVS icecast2, and darkice, but the only option seems to be if the same stream is actually encoded multiple times at different bitrates. This is not good for my cpu. Can I get bitrate scaled ogg streams working with the current tools?

I have some speech encoded at 140 kbps that I would like to have encoded at 40-60 kbps instead. I could just convert the file to wav and re-encode the file, but I seem to recall that ogg-files very easily can be converted to lower bitrates (something with cutting off the last bits). I would assume that this also will preserve more of the original data. Is there a utility for this? /Ole --

Hi, A simple question, that I would appreciate some opinions on: What are the advantages for using Icecast to stream static MP3 files rather than just letting Apache handle the streaming?

After reading http://mp3.radified.com/mp3.htm I sent Rad an explanation of some things as I understand them. He liked it and posted it on his site (still unlinked, use the URL below). Can somebody with better understanding of psycho-acoustic terms and the vorbis model check it and comment on it? In particular I didn't know how vorbis handles quantization noise. If you reply with
