Hi Brian,

I'm still interested in recording in flac format but i'm not very familiar with mod_sndfile.c (and not familiar with c programming either).

To get started, i tried to introduce the flac extension the same way oga extension was introduced :

} else if (!strcmp(ext, "oga")) {

context->sfinfo.format = SF_FORMAT_OGG | SF_FORMAT_VORBIS;

context->sfinfo.samplerate = handle->samplerate;

} else if (!strcmp(ext, "flac")) {

context->sfinfo.format = SF_FORMAT_FLAC | SF_FORMAT_PCM_16;

context->sfinfo.samplerate = handle->samplerate;

}

And i also added the extension in the list :

char *extras[] = { "r8", "r16", "r24", "r32", "gsm", "ul", "ulaw", "al", "alaw", "adpcm", "vox","flac", NULL };

then make & make install.

But my first attempt was not really successfull :

2014-07-01 11:47:36.670463 [ERR] mod_sndfile.c:205 Error Opening File [/var/callid:84/record0.flac] [File contains data in an unimplemented format.]

Does anybody have docs/guidelines on how to use libsndfile ?

..Adding formats would need you to modify mod_sndfile to enable them.

Subject: [Freeswitch-users] Fwd: Recording in flac format ?

Hi,

I'm using freeswitch version 1.4.5

I would like to record a session in .flac format.

I assume this could be somehow possible since FS rely on libsndfile-1.0.26pre5 and libsndfile claims flac support since v1.0.18.

I tried to compiled FS with instruction from description of https://jira.freeswitch.org/browse/FS-1197 :

Apt-get install libflac-dev and "./configure --enable-flac"..

However that didn't help, flac extension is still not usable on FS recording app.

Does anyone have an idea how to have flac format enabled ?

Regards,
