[Freeswitch-users] g729 sound format for Intel IPP codecs

[Anita Hall]

Hi!

We have been playing with Intel IPP G729 code and its module for
FreeSWITCH.

As reported here, we have successfully compile the fs-g729 module after
install IPP libraries.
https://code.google.com/p/fs-g729/issues/detail?id=3#c1

However, to test the codec in a loopback SIP call (FreeSWITCH calling
itself over SIP), I need some G729 encoded files (do I really?)

FreeSWITCH gives errors with G729 encoded file from here
http://www.enicomms.com/cutglassivr/audiofiles/Alison_Keenan-British-English-g729.tar.gz
Dialplan
<action function="play-file" data="ivr/demo-thanks.g729"/>

[ERR] switch_core_file.c:122 Invalid file format [g729] for
[/usr/local/freeswitch/sounds/en/us/callie/ivr/demo-thanks.g729]!

And also gives errors with file encoded using Intel IPP sample G729
encoder.
<action function="play-file" data="ivr/ivr-welcome_to_freeswitch.g729"/>
[ERR] switch_core_file.c:122 Invalid file format [g729] for
[/usr/local/freeswitch/sounds/en/us/callie/ivr/ivr-welcome_to_freeswitch.g729]!

Please note that the files are actually kept in the directory
/usr/local/freeswitch/sounds/en/us/callie/ivr/8000 as are other demo_ivr
sound files.

# file /usr/local/freeswitch/sounds/en/us/callie//ivr/8000/*.g72*
/usr/local/freeswitch/sounds/en/us/callie//ivr/8000/demo-thanks.g729:
data
/usr/local/freeswitch/sounds/en/us/callie//ivr/8000/ivr-welcome_to_freeswitch.g729:
RIFF (little-endian) data, WAVE audio, mono 8000 Hz

I suspect that ivr-welcome_to_freeswitch.g729 (produced by Intel IPP G729
encoder) is not really G729.

Any pointers will be most helpful.

Thanks!
Anita.
