[Freeswitch-users] Loop audio file with uuid_displace

[Ciprian Dosoftei]

Hello everyone,

I am looking for a way to execute uuid_displace in a fashion which would
loop the file indefinitely, til uuid_displace stop is invoked.

The confluence page does not advertise such options:
https://freeswitch.org/confluence/display/FREESWITCH/mod_commands#mod_commands-uuid_displace

However, upon digging deeper in the switch_ivr_displace_session function
(switch_ivr_async.php), it appears the last parameter of the command
(flags) is parsed somewhat different than suggested in the confluence page,
namely it would set bug's user data loop member to a non-zero value if the
'l' character is found in the flags argument:

if (flags && strchr(flags, 'l')) {
dh->loop++;
}

Subsequently, the displacement callback (read and write) do account for the
user data loop member when they are being invoked (i.e. evaluated in if
(dh->loop) statements), which suggest the looping feature/flag should be
supported. Nonetheless, I could not get it working by specifying 'l' as
uuid_displace fifth parameter.

Any advice is appreciated! See you all next week in Chicago!
