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

[Matt Murphy]

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!
