question: would it be possible to mess around with icecast2s' relay ability to kind of cheat a peelable streaming thing? eg: client needs a bitrate lower than what is available, client tells server this, server relays to itself, or other available server, at a required bitrate, server forwards new stream info to client and so on. <p>--- >8 ---- List archives: http://www.xiph.org/archives...

Hi all, last time I have seen discussions here about alternative encoders, or tuned versions of the encoder. Last year (sept/oct) there had been the discussion if existing streams will be peelable or if they have to be "modified" first to be peelable. Now for my question: Is it known allready if existing streams will be peelable or not ? Or, with other words: Is it known if the /can/ be modified in a way that they are peelable ? If so, will the stream loose in quality when doing...

...grats 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 created that way in the first place? in other words, if peeling is the most important feature for me, should i wait until a peeling-capable encoder is out? thanks, SM a_sh_am (at - sign) st_an_fo_rd (period) e_d_u [re...

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 decimal points of quality in at least oggdrop, giving 100 quantifiable levels per integer level of quality, giving 1001 from q0 to q10, and an extra 100 for q-1 to q-0.01). the 1101 encoder would then com...

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

Hi All, Let me ask this question of the group: When bit rate peeling becomes available, how will the quality of the peeled Vorbis file compare to a file encoded at the target quality directly from the original? So, for: a.wav --> b.ogg (at q6) --> c.ogg (at q2) a.wav --------------------> d.ogg (at q2) how are c.ogg and d.ogg likely to compare in terms of audio

I have run an ogg analisis using EAQUAL from -q 0 till -q 10 evaluating bitrate and quality. The results are shown in a nice graph, and can be seen here: http://audio.sinderman.com/ One thing I have found is a bug, as it is cleary shown by the blue lines. Other discoveries are written in that page, and others are still evolving in my mind :) The goals of this analisis is to help the developers

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.

...that it can encode exacty to the size of the CD (to maximize quality given a size restriction). It also says (in a separate point) that it uses two-pass VBR compression. >From that I guess they do something like encoding a bigger-than needed file and then throwing things out. But probably the peelable represantation is only internal to the plugin and more complex than packet truncation - hardly the SVCD format would support anything like the vorbis bit peeling... -- Beni Cherniavsky <cben@tx.technion.ac.il> (also scben@t2 in Technion) --- >8 ---- List archives: ht...

Hey y'all -- I heard some discussion a while back about "bitrate stripping" to reduce filesize without re-encoding ... has this gone anywhere?

Hi: I just wanted to know where exactly the problem with re-encoding in RC2 was. Was it in vorbis' ability to cope well with its own output as input, or did the first encode produce output that didn't lend itself to re-encoding? The difference is important. If it's the latter, anyone wanting to re-encode material will have to first encode it with RC3. I guess what I'm asking

Greetings, I thought this was supposed to be a list for educated people to discuss serious development of the ogg vorbis project. In light of that, it is amazing to see the level Mr. Segher Boessenkool drops down to in the last posts. More or less calling people insane and accusing them of being on crack and what not. I didn't want to post this on the list, for there is no reason to

NOTE: this is my understanding of the situation. I am not a Vorbis developer. RC3 streams are peelable. No tools exist to do so. (Except a proof-of-concept hack that (I think) Segher made at some point. Or maybe Monty.) RC4 is focused on tuning the lower sample rates (below 44.1 kHz) and on getting a proper bitsteam management engine in place. This is great news for people doing streaming w...

Hi- just wondering, what would be the best quality rating to use to fit lots of music into 10GB of HD space. The audio quality has to be high enough for it to sound good when played through PA systems (for when my college is stupid enough to forget to hire a DJ, or when the realise the DJ they always hire can't use a mixing desk properly) ranging from a functional PA system thats stuck in the

Are direct bit-rate converters possible for Ogg Vorbis? Or do they already exist? Even more, is it possible to directly convert MP3/ATRAC3 (i.e., Sony Minidisc) encoding to and from Ogg Vorbis? There has been an earlier discussion on this question. But this discussion centered around the fact that people couldn't see the point, and were rather hostile to the idea. There is a very good
