I am not aware of any "extra" avcodecs apt-get packages? If I check "show files" from fs_cli, "file,mp4,mod_av" is listed. and "show modules" lists  "file,mp4,mod_av,/usr/lib/freeswitch/mod/mod_av.so" From: Michael Jerris <mike@jerris.com> To: FreeSWITCH Users Help <freeswitch-users@lists.freeswitch.org> Sent: Thursday, November 5, 2015 12:20 PM Subject: Re: [Freeswitch-users] writing to mp4 file not work is the avcodecs extras package installed?

I installed libavcodec-extra module.  I did not realize non-freeswitch-XXX packages were needed. But still does not work.

[ERR] avformat.c:411 Could not open audio codec: Experimental feature It looks like it's trying to use the native AAC encoder instead of the VisualOn encoder. Install the libavcodec-extra package and see if it works after that.

One thing to note is that the native AAC encoder in ffmpeg is actually significantly better than the VisualOn encoder in quality - see  https://trac.ffmpeg.org/wiki/Encode/AAC which describes the encoders the ffmpeg can use. The issue is that enabling the native AAC encoder requires passing an additional flag to allow the "experimental" codec. I suspect that adding this flag would be a fairly simple patch to FreeSWITCH. -- Calvin Walton <calvin.walton@kepstin.ca> _________________________________________________________________________ Professional FreeSWITCH Consulting Services: consulting@freeswitch.org http://www.freeswitchsolutions.com Official FreeSWITCH Sites http://www.freeswitch.org http://confluence.freeswitch.org http://www.cluecon.com FreeSWITCH-users mailing list FreeSWITCH-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org
