Hi,

I setup FreeSWITCH 1.6 on Debian Jessie using the apt-get modules.

I have mod_av auto loaded.  When I try to "auto-record" to record to a mp4 file in /etc/freeswitch/autoload_configs/conference.conf.xml.

I get these errors:

[ERR] avformat.c:411 Could not open audio codec: Experimental feature
[ERR] conference_record.c:241 Error Opening File [{channels=2,samplerate=8000,vw=640,vh=480,fps=15.00}/var/lib/freeswitch/recordings/$1-10.61.82.56_2015-11-05-14-45-00.mp4]

Do I need to compile FreeSWITCH from latest source to get this to work?
