Hi All, I'm wondering about saving audio to a file. With MP3 & WMA there's support for tags - is there a file format for Opus with tag support? I guess I've missed something somewhere. Opus is excellent BTW, I use it in client/server radio communications software, http://v2.sdr-radio.com/ . Simon G4ELI/HB9DRV http://dit-dit-dit.com -------------- next part

Thanks for the quick response. That makes sense. I just wanted to make sure it wasn't an easy fix, or that I wasn't overlooking something. My scenario calls for very low latency playback with a user being able to jump between many files quickly, or seek quickly. This means I am priming the pump by downloading the first chunk of many files that are likely to be started soon. I was

Hello all, Attached are patches for libopusenc, opusfile and opus-tools in order to provide support for Ambisonics and the Projection API for encoding/decoding channel mapping 253 and 254. Please feel free to ask any questions or give any feedback you might have. :) Cheers, Drew -------------- next part -------------- An HTML attachment was scrubbed... URL:

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

Hi all, I am a developer for embedded system and totally new to Opus and open source audio codec. I'm now using Microchip dsPIC33 to develop a decoder for Opus. I am now using sources of libopus. The first question is for calling opus_decode(), do I need to skip the header bytes of an opus file before I can input the file data to opus_decode()? Or will libopus handle this automatically?

Ideally, of course, libopusfile would continue to work with older

As you say it's a bit complicated, although oggenc has a lot of extra support for controlling encoder options you

Hello, I just started into the world of OPUS. I would like to know what is the best way to build the Opus library and Opus tools on a Windows 7 pc. I see that the Opus library and the Opus tools packages have a few Makefiles. It also mentions mingw as an option for building. Is it somewhere explained what are the steps needed, or does anyone have some tips? Thanks, Met vriendelijke

In addition to what Tim said, do you get the same error loading

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

Hello Tony, opusenc from opus-tools works for me.. Just tried it successfully on my x86_64 Ubuntu Trusty 14.04 box. I was just able to do $ sudo apt-get install opus-tools $ opusenc music_48kbps.wav music_48kbps.opus I remember also being able to compile opus-tools (git://git.xiph.org/opus-tools.git) some time ago.

Dear Opus community, I'm trying to build opusfile as a shared (.dll) library on Windows 10 using Visual Studio 2017. I know there are prebuilt libraries, but those are depending on a whole bunch of other libraries and x86 (32 bit) only. Whenever I try to build opusfile, it generates opusfile.dll, which is basically empty (no functions), which makes it unuseable. This is most likely because

Which one of the various libraries on xiph.org allow me to create an Opus file? The 3 or so libraries on the Opus download page all seem to be for reading files, converting and/or encode/decode streams. I have device that outputs a stream of Opus 'frames' and I need to save them into an Opus file. -- Tony -------------- next part -------------- An HTML attachment was scrubbed... URL:

AC_SEARCH_LIBS will give a result of "none required" if the relevant function is available without any special libraries. (This is the case for lrintf on MinGW.) Make sure this special value isn't put verbatim into the pkg-config files, as it would cause the linker to search for files named "none" and "required", and fail. --- configure.ac | 6

I would like to decode an Opus file in chunks (e.g. 16K byte array). Is this possible with the Opusfile library or would I need to interface directly with libogg and libopus? It seems like the Opusfile decoder functions maintain an internal pointer/state for OggOpusFile during multiple calls to op_read(OggOpusFile *_op ...) and a complete byte array of the entire Opus file would be needed.
