TRY THIS Incredible PBX - Pi2 - Opus Codec not working

Algis · Sep 11, 2017

I recently installed Incredible PBX 13 on a Raspberry Pi 2 and noticed the opus codec is not working. I am not sure what I would need to do here as the documentation states opus is supported, and I would assume I do not need to recompile.

Any suggestion are appreciated. Below is some information and details to confirm my issue. Thanks!

- I enabled and moved up the opus codec in webgui: Settings > Asterisk SIP Settings > Audio Codecs (submit/apply config)
- I did the same on the phone (opus as priority)
- I called *60 from a Grandstream 2140 phone (which supports opus), it connected, then disconnects, all other "opus" calls fail, g722, g711, etc work fine. Also tried with soft clients as well.

- In Asterisk CLI debug on I receive:

Code:

[2017-09-11 18:09:16] WARNING[11793][C-00000014]: codec.c:397 ast_codec_samples_count: Unable to calculate samples for codec opus

and

Code:

[2017-09-11 18:09:17] WARNING[11793][C-00000014]: channel.c:5540 set_format: Unable to find a codec translation path: (gsm) -> (opus)

- I check translation table (no opus):

Code:

          Source Format (Rows) Destination Format (Columns)

I attempt to manually load the opus module (fail):

I also check to see that xmlstrlet is on my machine (yes):

@Algis Try this:

Code:

apt-get install libopus-dev

Algis · Sep 13, 2017

Thanks for the quick feedback. It installed without any errors, but unfortunately I don't see any change. I still receive the same errors when I attempt to use the opus codec.

I suspect this warning(but I could be wrong):

Code:

[2017-09-11 18:25:20] WARNING[12419]: loader.c:556 load_dynamic_module: Error loading module 'codec_opus.so': /usr/lib/asterisk/modules/codec_opus.so: cannot open shared object file: No such file or directory

Has the most information, but I don't really know what this means

...and I can't seem to find a simplified answer with google. If I do get it to work, I will be sure to update this post.

Probably have to recompile Asterisk after installing that package.

pianoquintet · Oct 3, 2017

I have the same issue. The files do exist in the modules directory but they cannot be loaded, I believe, because they are compiled for an x86 platform. They are downloaded directly from the Asterisk website during the installation procedure. I noted this line in the log when executing "make install": "codec_opus: Downloading http://downloads.digium.com/pub/tel....0/x86-32/codec_opus-13.0_1.1.0-x86_32.tar.gz".

Could a solution be to backport package asterisk-opus from the debian stretch repositories? That package contains the following files, among others:

/usr/lib/asterisk/modules/codec_opus_open_source.so
/usr/lib/asterisk/modules/format_ogg_opus_open_source.so

@ostridge: That update is for Debian 10 x86_64 platforms, not Raspbian.

kenn10 · Apr 21, 2022

All of my Debian 11 systems with Asterisk 19 and FreePBX 16 already had Opus installed.

The DEB22 Opus msg - no such dir lib64 so obviously benign.

on 2020.3 for Raspberry Pi 3B (non 2021) Raspbian10 gets update202035

At some stage the auto update on PBX 2021.01 for Raspberry Pi 4B Raspbian10 - got switched from the update202035 stream to the updateDEB22 - presumed to be on the conversion to 2021. Is that not correct?
