Summary:                    mp3 playback not working via AGI "STREAM FILE", but
"EXEC PLAYBACK" works
Description: 
-Ubuntu 8.10 x64
-Using Asterisk 1.4.24 (compiled from source), Addons 1.4.7

Trying to play an MP3 file via FastAGI "STREAM FILE" and/or "GET DATA"
commands fails, with the command returning immediately (log attached). We
have tried two different types of mp3 files:
-16-bit, 44.100kHz, CBR, 128kbit
(http://asterisk.gnuinter.net/files/digium/asterisk-ng/sounds/fpm-calm-river.mp3,
from the standard asterisk-addons distribution)
-16-bit, 11.025kHZ, CBR, 32kbit

Playing either mp3 with the Playback() callflow command (from
extensions.conf) works fine. It just seems that things are broken with
AGI.

This is a problem for us because EXEC PLAYBACK can't take DTMF. We need to
process DTMF like STREAM DATA allows for.

The AGI server script we are using is attached.

Note that in the log snippets you will see mention of voiceglue/phoneglue.
This is because we are working the voiceglue folks to get mp3 playback
working with it, and saw this bug. Note that in this testing here, we have
totally removed voiceglue out of the picture. This is just plain old
asterisk playing a plain old MP3 file.

Just to clear up some possible confusion, with the text:

"Playing either mp3 with the Playback() callflow command (from
extensions.conf) works fine. It just seems that things are broken with
AGI."

I mean that things work with Playback either with it being called directly
from extensions.conf, for via EXEC PLAYBACK with AGI. What seems to be
broken here is not AGI per se, but the STREAM DATA/GET DATA AGI command
integration with format_mp3 at some level.
