Re: [Linphone-developers] Configuring Linphone to use Opus on BeagleBone Black

[Matt Murphy]

Guillaume - you are a national treasure!

Sure enough, I took a peek at /usr/local/lib/pkgconfig/opus.pc:

# Opus codec reference implementation pkg-config file

prefix=/usr/local

exec_prefix=${prefix}

libdir=${exec_prefix}/lib

includedir=${prefix}/include

Name: Opus

Description: Opus IETF audio codec (fixed-point build)

URL: http://opus-codec.org/

Version: unknown

Requires:

Conflicts:

Libs: -L${libdir} -lopus

Libs.private:

Cflags: -I${includedir}/opus

I manually updated the version to 0.9.14 just to see what would happen. I reconfigured and Opus is now found. After the build I did a codec list command in linphonec and opus is now available. I will run through some tests to be sure all is well, but this appears to have solved it. I want to educate myself on why the version was tagged as "unknown" in the first place, but at least I am back on track.

Excellent work, Guillaume! I can't thank you enough for all your help!

Hey Matt,

I suspect Opus doesn’t set the version in its opus.pc file. Could you check that ? It should exist in /usr/lib/pkgconfig/opus.pc

On my Ubuntu here, there is no pkgconfig file, so that might explain the problem.

You could try to set the _CFLAGS and _LIBS by hand, yes, and see how it goes.

Otherwise, you could try compiling the opus version that we use in our mobile apps: git//git.opus-codec.org/opus.git at commit da97db1ca1f92592af3534c9a2596da0e9a009ca

It embarks a .pc file which will be picked up by pkgconfig.

Once you install this opus (in a prefix, say $PREFIX) you should configure linphone with:

PKG_CONFIG_PATH=$PREFIX/lib/pkgconfig ./configure --enable-fixed-point --enable-opus CFLAGS="-march=armv7-a -mtune=cortex-a8 -O3 »

Hi Guillaume,

Thanks a lot for the quick reply. I pulled up the config.log file as requested. It seems like there is a problem determining the version of Opus I have installed, which seems a little odd.

Here is the relevant snippet:

configure:21429: checking for OPUS

configure:21436: $PKG_CONFIG --exists --print-errors "opus >= 0.9.0"

Requested 'opus >= 0.9.0' but version of Opus is unknown

You may find new versions of Opus at http://opus-codec.org/

configure:21439: $? = 1

configure:21453: $PKG_CONFIG --exists --print-errors "opus >= 0.9.0"

Requested 'opus >= 0.9.0' but version of Opus is unknown

You may find new versions of Opus at http://opus-codec.org/

configure:21456: $? = 1

configure:21470: result: no

Requested 'opus >= 0.9.0' but version of Opus is unknown

You may find new versions of Opus at http://opus-codec.org/ 

  

I also have these Opus references in the config.log file:

ac_cv_env_OPUS_CFLAGS_set=

ac_cv_env_OPUS_CFLAGS_value=

ac_cv_env_OPUS_LIBS_set=

ac_cv_env_OPUS_LIBS_value=

BUILD_OPUS_FALSE=''

BUILD_OPUS_TRUE='#'

OPUS_CFLAGS=''

OPUS_LIBS=''

I guess I would expect something like:

OPUS_CFLAGS='-I/usr/local/include'

OPUS_LIBS='-L/usr/local/lib -lopus'

 

Do I need to manually add the OPUS_CFLAGS and OPUS_LIBS?

I really appreciate the help, thank you so much!

Hey Matt,

Can you take a look into the mediastreamer2/config.log file to see why mediastreamer2 doesn’t see the opus codec?

Greetings everyone,

I am attempting to build Linphone on my BeagleBone black (BBB) and I want to do some tests with the Opus codec installed. I have successfully put Linphone on another BBB and it works flawlessly using speex. My issue is that I can't ever get opus recognized when I run ./configure.

I always see the following:

...

checking for SPANDSP... no

checking for LIBUPNP... yes

checking for OPUS... no

checking for FFMPEG... yes

checking for SWSCALE... yes

...

I have tried installing opus-1.1 from source and ldconfig seems to indicate that all is well, because I see:

libopus.so.0 (libc6,hard-float) => /usr/local/lib/libopus.so.0

libopus.so.0 (libc6,hard-float) => /usr/lib/libopus.so.0

libopus.so (libc6,hard-float) => /usr/local/lib/libopus.so

libopus.so (libc6,hard-float) => /usr/lib/libopus.so

I have also tried using apt-get install libopus-dev opus-tools, but still no joy.

I can successfully use opusenc to encode a wav file, so I get some satisfaction from that.

But if I build linphone, I never see opus show up as enabled or disabled when I do a codec list command.

If it matters, I am doing configure like this:

./configure --enable-fixed-point --enable-opus CFLAGS="-march=armv7-a -mtune=cortex-a8 -O3"

Any thoughts on what I can try to get this working?

Thanks for your help!
