similar to: Random access Vorbis decoder in Java

Hi, I am trying to implement a Vorbis decoder in Java, and I have some problems understanding the file-format specification included with libvorbis. In the header description, there are a few obvious mistakes, which I believe to have solved, but when I try to decode the audio packets, the decoded floor and residue data doesn't seem to make sense at all, and after a few packets, my decoder

I'm considering creating an ogg vorbis decoder chip for my senior project in school. At this point, my idea is to have a program (such as XMMS, ogg123, WinAMP) send the encoded ogg bitstream through a USB port to my project, which is then decoded. My project then returns the raw PCM audio, which is then handled by the player program for final audio output. I'm planning on USB as it

I've been trying to get oggdec to work with input streamed in through a pipe or a socket. This seems to work on Linux and OS X, but not on Windows. I've found that code in vorbisfile.c tests the input stream for seekability by invoking fseek in the following way: int offsettest=(f?callbacks.seek_func(f,0,SEEK_CUR) : -1); Unfortunately, fseek succeeds for a socket on Windows (even

Hi! Is there any Java Vorbis player that works on MIDP 2.0 platforms (mobile phones) ? I know the pure Java players, but I'm looking for a mobile version.

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

I'm open to flames if this has already been posted. http://www.sparkfun.com/commerce/product_info.php?products_id=8300 As of April 17th, SF listed a new Ogg Vorbis decoder chip that is seriously listing for $10 USD. I'm excited. I think I'll buy a couple and integrate them into an IR streaming project I've been tinkering with. -Chris Harrington

Hello, I am currently developing a ogg vorbis decoding module for use in winlame (a LAME frontend), and I have some questions: To do a decoder I used most code in decoder_example.c, but I think there is something missing. I would be glad if someone could look at this code: http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/winlame/winlame/source/winlame/wlOggVorbisDecoderModule.cpp and

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

Hi there, I have develope pure Java Ogg Vorbis decoder and its working version is now available at http://www.jcraft.com/jorbis/ . Of course, it is under LGPL. I think that the ubiquitousness of Vorbis decoder will leverage the popurality of Ogg Vorbis. Current version can decode Ogg Vorbis bitstreams, but its outputs are extremely noisy and more works must be done. I'm very happy if I

The IETF passed the application/ogg MIME type some days ago. I couldn't bring you the news earlier because of the MS SQL worm that has been wreaking havoc all over my local networks. The IETF wants some clarifications in Silivias draft for the Ogg stream format, but apart from that I think it will also be passed soon. The RFC and IANA registration of this mimetype will probably be published

Hi All, I am getting this error when i try to compile the "Linphone" package by typing----- make. please help me i am feeling very frustrated with this error pasdt from 7 days i am getting this error. please help me. speexec.c: In function `speex_ec_process': speexec.c:112: `spx_int32_t' undeclared (first use in this function) speexec.c:112: (Each undeclared identifier is

There isn't a lot of guidance on how exactly to run the codec I compiled out of cvs just now, but I expected the following to work: cat test.wav | encoder_example | decoder_example But the decoder fails with: End of file before finding all Vorbis headers! Is this a bug? Or am I missing something fundamental? Should I attach the test.wav? -- Daniel --- >8 ---- List

Hi! I would like to decompress an ogg vorbis file from the memory to the memory. I wrote my own callbacks for it (Why isn't there callback functions for it? Just for void* data, and a size_t size). Now I can read the ogg file from the memory but I don't know the total size of the uncompressed data (I would like to decompress the data at once). How can I get the bitstream decompressed

Hi All, I?m new to Vorbis and planning to port Fixed point Vorbis decoder on Xtensa based embedded platform. My limitations include limited program and data memory and port of Vorbis not supposed to use dynamic memory allocation. Multiple instances of Vorbis can be invoked and all of the resources allocated to each Vorbis instance should be decided by upper layer. My quarries are: [1] What is

Hi all, Does anyone have any experience porting libvorbis to platforms with small total memory sizes? Specifically, I'm trying to figure out if it's feasible to run Ogg Vorbis decoding on one of the PlayStation 3's SPU's -- secondary processors with only 256kb of local memory. It looks like out of the box the memory footprint of libvorbis is roughly: ~130k code ~60k static

I have checked in a few changes worth noting: 1. I split the file decoder into a more general 'seekable stream decoder' which, makes the file decoder just a special case of the seekable stream decoder. this is useful in situations where you are trying to add decoding support to something that has abstracted the file away. the file decoder interface is still identical, it is all backward

Ah, OK, I understand where you're headed now. The libvorbis API is different than
