Problem compiling opus-tools-0.1.7
Hi
I'm having a problem compiling opus-tools-0.1.7.
Version opus-tools-0.1.6 seems to compile OK.
I've tried with opus-1.0.3 and opus-1.1-beta.
The errors are like this:-
"undefined reference to `sqrtf'" etc.
This OS is Peppermint Three, similar to Ubuntu 12.04.
It uses:-
gcc --version
gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3
Google says it's maybe something to do

Indeed. The opus-tools build explicitly adds -lm for opusdec and opusenc

Compiling FFmpeg with libopencore-amrnb and opus-git.

Any idea what's causing these errors:-

Thanks Jean-Marc
I will stay with opus-1.1-beta for now and keep watch on opus-git summary to see if/when the rename appears.

AM335x ARM Cortex-A8 performance drop opus 1.1
Hello!,
i've just compared the 1.0.3 release with the master branch
on a BeagleBone Black (AM335x 1GHz ARM Cortex-A8 with NEON
floating-point accelerator) and Arch Linux ARM.
At the moment I dont no why, but I see that 1.1 is much slower
in encoding. Are there any default changes, that I missed and could
explain this? Normaly I suggested a better performance with 1.1 and

Opus cmake build
I tried the new cmake-based build system to build Opus on Linux and
macOS. I'm not familiar with cmake but based on instructions I found
online I used it as follows:
- mkdir build
- cd build
- cmake -DCMAKE_INSTALL_PREFIX:PATH=<install-path> ..
- make
- ctest
- make install
Although the "make" command completed, it reported that optimizations
were disabled:

Problem compiling opus-tools-0.1.7
Hi,
Seems like it's not linking with libm. I suspect it has to do with
linking statically with libopus.a (is that intended?). Maybe opus-tools
relies on the fact that libopus is linked with libm and doesn't
explicitly add it? Greg?

Opus on MIPS performance
Hi All,
First time poster to this group, please ignore my ignorance?
I?m trying to use Opus 1.1 on a 400MHz MIPS 24k CPU (AR9331, specifically, like in the Arduino Yun).
I?ve successfully built (I think) opus-1.1 and opus-tools-1.8 and they run, but are dog slow.
opus-1.1 does have the ?enable-fixed-point option set, as this chip only has soft-float.

Possible bug in Opus 1.3 (opus-tools-0.2-opus-1.3)?
Hi!
Playing with Opus 1.3 I converted a tone sweep with a sample rate of 96kHz (just for fun). Before I had converted that from WAV to FLAC, and to Vorbis without problems.
With Opus I noticed that the file size for 48kHz and 48 kbps compared to 96kHz Vorbis at 31kbps is about double the size and it sounds even worse (than Vorbis) (there is a lot of noise in the lower frequencies when a low

Help building OPUS library using FIXED_POINT option
Hi,
We are rebasing our audio compression subsystem using OPUS rather than SPEEX. The platform is Android but this piece is written in C code: we need to support armv5/armv7/x86 architectures.... and we use the released opus-1.1beta package from here<http://downloads.xiph.org/releases/opus/opus-1.1-beta.tar.gz>.
A lot of our OPUS build system + code to drive the audio compression has been

quality opus_demo vs opusenc
Hi,
I have found differences in quality between opus_demo and opusenc/opusdec.
I used for both applications the same raw pcm file,16 bit,48khz,litle
endian. i use libopus 1.1-beta and opus-tools-0.1.7.
The command for opus_demo is:
opus_demo audio 48000 1 64000 -cvbr -framesize 10 in.pcm out.pcm
For opusenc/dec:
opusenc --raw --raw-chan 1 bitrate 64 -cvbr --framesize 10 in.pcm in.opus

Opus Major Version Benchmarks on Raspberry Pi
I wanted to roughly benchmark how the different version of libopus
performed at each complexity level for a 6kbit/s output opus file. This was
conducted on a Raspberry Pi so it is a constant hardware platform. This was
done on an early Pi so only 256MB RAM but it was never used up so should
not make a difference.
I compiled the three final versions of each major release of libopus so

quality opus_demo vs opusenc
Hi,
I am interested in this part of the answer:
"Make
sure both are also linked to the same libopus (opusenc could be using
the system libopus 1.0.x while opus_demo is from git)"
I dowloaded a tarball distrib of libopus (1.1-beta),build and
installed it,and afterwards did the same with opus-tools (0.1.7),using
the former installed libopus library (also using libogg 1.3.1).

minor issue using opus-tools
hello all - this is probably something simple, but i am on-the-road and cant find a quick solution. ?i cant seem to get the opus toolset to recognize the ogg library. ?i was able to successfully get opus to work with FFMPEG, but not the toolset.
when i go to install opus-tools, i get the following message:
No package 'ogg' found

Sadly that's the best option currently. As you say it's a bit
complicated, although oggenc has a lot of extra support for controlling

Opus decoding performance on ARM devices
Hi everyone,
I have lately been evaluating the performance of various audio decoders,
particularly for ARM devices (Cortex A8 / A9). The context is audio
playback in a game engine, and thus decoding performance is of particular
interest.
Looking at Opus versus Vorbis on a Cortex A9 smartphone, the numbers look
approximately like this:

How to wrap Opus data in an Ogg stream?
Hi.
I am trying to understand how to package opus-encoded data in an ogg stream to make a standards-compilant ogg/opus file. Most things are clear, but there is one thing I simply do not understand.
What I do understand is that Ogg is based on pages, that each come with a fairly sizeable header (>=27 bytes). Now, I encode with a fairly low bitrate, so my opus packages are <100 bytes long.
