[Freeswitch-users] Method of checking if media is being played at a session

[Michael Lutz]

Hi Hynek (or anyone else ;-)

Thank you for your response. I see you also use the ESL to invoke the
playback? Is there a particulair for that other than I am using the
UUID_BROADCAST using the api?
I am trying to make it work through the ESL but it seems the initial
events are not received directly after the the broadcast, but it takes
a while. I will paste some example code of what I have done/am trying
to do.

Any help apreciated!

In this example I have created a couple of functions (explained in
code) and try t odo an async playback of an audio file, wait for the
ESL to confirm the PLAYBACK_START and then call another function which
waits for all PLAYBACK_STOP's (sum of plays) to return. Then I do
session:hangup. But it never gets the ESL event.

In theory this should work. But in some way the events do not come in
right away. This code is testable. (only specify a valid filename in
the streamFile)

Code: http://pastebin.com/ri0L7wmx

Regards,
Michael Lutz.
