[Freeswitch-users] How to query current playback position?

[Avi Marcus]

It looks like those variable are only updated upon PLAYBACK_STOP event,
since the line before is:
switch_log_printf(SWITCH_CHANNEL_SESSION_LOG(session), SWITCH_LOG_DEBUG,
"done playing file %s\n", file);

Can we make a feature, e.g. with uuid_fileman to query that for a live
playing file?

When I stop the file to get the position, it's destructive: I have to do a
new playback to get back to my position, and to get all my key bindings, I
need to transfer to an extension with them, and then I lose the position in
the IVR.

Thanks.
