The basic format is shared with Vorbis, but the 'magic signature' is different ('OpusTags' instead of '0x05vorbis') and vorbis puts a 0x01 value in an extra byte after the last tag. The OpusTag packet layout is described in

Hi Amit, I'm not sure what you're trying to ask, but the reserved space in the header is an optional thing. Encoders are free to do it, but are not required to do so.

The overhead of Ogg (in file size) is pretty small and it's efficient enough for most applications (and uses far less CPU than the codec anyway). If anything, you might want to look at optimizing the existing Ogg implementation (e.g. like Tremor did in the context of Vorbis). Of course, you're always free to design a new container, but I doubt it's worth it and it's a lot of work

Hi all! Using the code in opus_demo.c I write a c program for encode and decode the audio from one microphone, I can encode and decode raw audio into .opus file, but really is not an opus file because i need to add the "OpusHead" and the "OpusTags". In order that any opus player can play that file. So I only need in my c program how to add this streams to my file an how to

Hi Jean The problem is that for using this package I need to use all the libs like ogg, even Speex?, no, and also where i can find an easy example like opus_demo.c to create the .opus file Greetings Toni 2013/10/28 Jean-Marc Valin <jmvalin at jmvalin.ca> > Hi Toni, > > The package you want is opus-tools.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I'm pleased to announce the availability of opusfile v0.4. The opusfile and opusurl libraries provide a high-level API for decoding and seeking within .opus files on disk or over http(s). * https://ftp.mozilla.org/pub/mozilla.org/opus/opusfile-0.4.tar.gz * https://ftp.mozilla.org/pub/mozilla.org/opus/opusfile-0.4.zip *

Hello Jean-Marc, As an example, I am using the output of opus encoder to store the file as the following format and read back the same during decode process, without having much overhead.

I am writing a program that retrieves and plays .opus files over the network. I am using the C# PInvoke wrapper OpusFileSharp, which calls into libopusfile and passes callbacks for read, seek, and tell. I want to enable seeking via the seek callback by not returning -1, but I find that as soon as I do libopusfile requests the last 64K of the .opus file, probably so it can calculate the

Hello, Been playing with libopusfile today. Ideally would like an MSVC dll rather than a static lib, but I can't see dllexports hidiing in an #ifdef anywhere. Am I just being stupid, or....? BTW that static lib is working nicely in vs2010 and up for streaming radio, though it was a real pain to have to piddle about compiling openssl on Windows! I want to write a streaming URL source filter
