[Freeswitch-users] mod_shout.c:497 write_stream_thread() MP3 encode error -3!

i am trying to stream a conference call via icecast2 i have an extension set up as follows: <action application="record_session" data="shout://source:password@localhost /lecture.mp3"/> <action application="conference" data="fs"/> when i dial the extension, i am able to connect to the conference and the lecture.mp3 stream appears for about 5 seconds and then it disappears. also i get an error message in the freeswitch console as follows: mod_shout.c:497 write_stream_thread() MP3 encode error -3! i've tried many variations of this extension with no success. i am able to play mp3s during the conference and also record the conference to an mp3 so i know that mod_shout is working. any help would be much appreciated. thanks.
