similar to: Implementing Vorbis in hardware

Hi there I'm trying to use Vorbis in a slightly unusual way, and I'm a little unclear if I'm going to be able to do what I want to do nicely, or at all. Many apologies if I'm on the wrong list, or if this is a FAQ, or off-topic. I'd be very happy to be re-routed! I'm doing a little experimental work on a block-based bitstream format for object audio streaming. This format

I was wondering about Vorbis compatibility. It seems that wavelets and joint-stereo could be introduced later on Vorbis. I know the specifications are now frozen, but there is no real spec docs yet. So will the vorbis players still be able to decode Vorbis once joint or wavelet will be introduced, or will they need to be updated? Regards, -- Gabriel Bouvigne - France bouvigne@mp3-tech.org

As it seems that the vorbis decoder is now stable with respect to format/features, would it be time to start thinking about a hardware implementation? I would be interested in pursuing this if some there is consensus on requirements. If there is some enthusiasm for it then a module could be set up on the opencores site for a gate-array decoder. cya, Andrew... --- >8 ---- List

I am a bit confused to how Ogg/vorbis works. This is my understand. Vorbis is an audio codec that can be used instead of MP3 and it is open source. If this is true, what is Ogg? I think it is some kind of wrapper that allows you to stream Audio and Video. Am I right? Also I want to encode short videos in Xvid and then encode the audio in vorbis. Then I want to stream this over the Internet

Interested in building a speex codec (basically audio <-> speex <-> data stream) using TI's small MSP430 microcontroller. Is there any way to estimate feasibility based on CPU requirements? Example - speex is happily encoding on an old Pentium-1 processor (166 MHz) using about half the CPU (as reported under Linux); the TI microcontrollers are much slower yet (8-16-25 MHz) and

I downloaded test vectors from opus-codec.org site. The site indicated that the test files are intended for verifying that the Opus decoders are operating properly. I assume I could also use them to verify my encoder implementation, right? For example, use testvector01.dec as input to my encoder and compare its output bitstream with the corresponding testvector01.bit bitstream file. Any idea

Hi, I'm busy working on a method of synchronising playback between two ogg decoders. To do this reliably, I need to create a cross-reference of the raw & pcm offsets in the bitstream. I have tried using the ov_raw/pcm_tell calls, but it appears as if the ov_raw_tell() only updates itsself in steps of 4096 bytes (as each read callback is done). This gives me a cross-reference every

Greetings, I'm RP for a fairly large chunk of IP real estate. I carved out a /27 segment for my home network. Which is currently running over a cisco 837 GW (adsl/router). I'm not really keen on it (the router/modem). So I thought to myself that it couldn't be /that/ hard to build a box with FBSD that could replace it - am I crazy? Wouldn't it be possible to upload a minimal build

Hello, I'm undergoing a project in which I'm researching the viability of different portable audio formats for implementation in hardware. I have owned, for a number of years, Creative's Nomad II MG portable MP3 player, and recently posted several messages asking about Ogg Vorbis support on this product line. Amongst flames and miscellanous trivia, somebody from Creative actually

I'm pleased to announce the official freeze of the theora 1.0 bitstream format. We wanted to reserve the right to change things if we discovered any issues during the documentation documentation phase. We haven't, so there's no reason to delay adoption any further. The files produced by the alpha-3 encoder constitute the baseline of the theora I format and will be supported by

I am looking for estimated hardware requirements for running a 50 to 100 seat call center off of a single Asterisk server. The Asterisk server will have one quad T1 card installed (probably a Digium TE410P) with two T1s connected. The OS is Debian GNU/Linux (woody) with a custom 2.4.xx kernel installed. It is preferable for the server to have a single CPU and no shared IRQs. I would really

Hello, my name is Christopher Timko. I am currently a Senior at the University of Arkansas majoring in computer engineering. As part of our graduation requirements, we must complete a design project. Students are encouraged to chose open source technology, since a network of development exists for most of these ideas. I have decided to investigate the feasibility of creating a hardware

Hello, I would like to "piggy-back" other data in an Ogg/Vorbis I physical stream (i.e. file) in a manner that does not conflict with specifications and existing decoders/players/editors etc. As far as I can see, I have some possible choices: 1 - Chaining a logical bistream at the end. If this is the way to go, two questions arise to begin with: q1a - How to identify this stream in a

Hi Developers, I searched the archives and found a discussion about hardware decoders using dsp chips. Has anyone done any research or development on a high-speed encoder? I think it would be cool to have an encoder that could keep up with the high speed cdroms on the market. I was thinking of getting one of the evaluation kits from TI or Analog Devices and trying to port the library to them.

Hi list, I'm doing some experiments with relatively low bitrate encoding, and can't find a player/decoder that works consistently. Winamp and freeamp seem to choke up when you try to play low-bitrate vorbis files. There's mention of an ogg123 player/decoder, but it doesn't seem to be includeed with the vorbis-tools package as advertised. (Does anyone know where it is? Is

iRiver released some firmware updates today for many of their CD and Flash-based MP3 players. Among the added features is the ability to play back Ogg Vorbis and FLAC audio files. Interestingly, in order to make room for the decoders, they also _removed_ the ability to play back Windows Media Audio. It's unfortunate that they had to take out some capability, but I'd prefer Ogg to wma
