[Freeswitch-users] Recording background music and voice is outof sync

[Daniel Liang]

Hi Brian,

I have created a new thread regarding this issue a few days ago, you may
have missed it. So, I am reposting the same content there:

What I did was the following:
 
First, I sent the playback command:
 
call-command: execute
execute-app-name: playback
execute-app-arg: <filename>
 
Then I sent uuid_record (Sorry, it was not Record command):
 
api uuid_record <uuid> start <filename> 120
 
I also tried replacing the playback command with:
api uuid_displace <uuid> start <filename> 0 mux
 
But the end results are the same. The recorded user's voice is about 0.5
second behind the expected result.
 
Thanks,
Daniel

Can you show us an example of how you're doing this?  Playback and
Record aren't async so you'll need to show us how you're doing this.

Also don't hijack threads you hit replay on the one "Re: [Freeswitch-
users] FreeSwitch setup as a "Dumb" SBC" as the subject, deleted the
subject and started a new body.  That hijacks the thread and that can
cause your problem to go ignored in some cases if people aren't
interested in the thread topic depending on how their reader threads the
emails.

Please click new message and type freeswitch- users at lists.freeswitch.org
in and then input your subject and body to start a new thread.

Thanks,
