AM335x ARM Cortex-A8 performance drop opus 1.1
Hi,
Just to clear things up... So 1.1 has some new analysis code that
increases the amount of CPU. When building as floating point (which you
appear to be doing, right?), the new code is enabled at complexity 7 and
up (opusenc defaults to complexity 10 IIRC). This is why you've been
seeing an increase in the CPU time. In version 1.0.x, complexity 5-10
are the exactly the same for music.

libopus and TI am335x with linphone
Hello,
has anyone running a linphone-application on am335x (like beaglebone) with opus codec.
My CPU has extreme high load, wenn ist start with opus codec.
Is there a possibikity tu optimize f?r this single core ARM?
Thanks
Helmut Sholz

libopus and TI am335x with linphone
Hello,
you can compile opus with "--enable-fixed-point". That saves a cpu
ressources.

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.
My short test file (less than one

Is OPUS_AUTO the default for an encoder's bitrate?
I had expected that the default bitrate for the encoder would be the same as setting it to OPUS_AUTO, but I'm getting difference results:

1.1 Much slower on Raspberry Pi
Christian,
I will give 64kbit/s a try and post the figures. My own project is voice
only and requires low bitrate so was hoping that it was just the way I was
compiling and not an actual regression in speed for SILK. The raspberry PI
is quite a cheap and handy reference platform though the ARM side is fairly
underpowered but has a great GPU. It also has no audio in which is a pain

1.1 Much slower on Raspberry Pi
I have just started trying Opus with a view to using it in a project. I am
interested in embedded hardware and tried it on the Raspberry Pi using the
raspbian distro.
The version of libopus in the repos is 0.9.14. I installed this and tried
encoding 2 minutes of speech from a librevox recording. It managed this at
a respectable pace for complexity 10:

Need Help !
I am interested testing opus codec encoding decoding qaulity. for this have complied opus code codec from souce. After compiling i got opus_demo app.

inbandfec is adding samples
I didn't expect this, is it normal? When you use inbandfec, and have packet losses, you end up with more audio samples than you started with.
With short frame (2.5), the FEC isn't supposed to do anything but it shouldn't do that should it? and 20mS frame, should do 'something' but? add audio?
I'm using opus_demo for this.
Here's the steps (I have my test audio in

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

ruby on rails on ARM am335x
Hi all,
have you ever experience ruby on rails on a embedded linux SO? For example
on beagle bone''s arm.
I''m assessing for my web server scripting language: php or ruby on rails?
I''m a total novice on ruby on rails. Any ideas or tips are welcome.
Best regards

Sorry. I meant that in a _fixed_point_ build the new analysis code is
enabled only at complexity setting 10. It's currently enabled for
floating point builds at complexity 7 or higher. Both fixed and float
builds default to complexity 9 in 1.1.

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:-

Encoder state management - 'chunked' Opus?
Hi,
I'm playing around using Opus in a 'chunked' streaming context, where
chunks of media are served in separate HTTP responses.
I am trying to hunt down the source of some clicks-and-pops during
playback, and while it is very likely that these glitches are due to the
low quality of my code, I wanted to ask if the admonition in the API
docs[1] that "encoder state *must*

Beginner's questions/suggestions
Hi!
I was just trying libopus0-1.1-3.2.x86_64 and opus-tools-0.1.9-3.2.x86_64 on openSUSE Leap, and I was wondering:
opusenc does not display the file name it processes. In Lunux when you use some batch processing, it might be interesting! Example output for
"for f in *.wav;do opusenc --bitrate 160 $f ${f%.wav}.opus; done":

Why does this code not generate a valid opus file?
Hi.
I assume that I am deeply stupid and have missed something obvious, but why does this bare-bones code not generate a valid (If trivial) opus file?
Running opusinfo I ge the following which I interpret this to mean that not even the first packet gets a pass:
New logical stream (#1, serial: 1f0cce42): type opus
WARNING: Could not decode Opus header packet 0 - invalid Opus stream (1)
