I added the proper commands using libtool --mode=install and the missing libs location; working fine now. The issue I'm having now is about freeswitch being unable to identify the network interface addresses, so the daemons refuse to start. After that, I need to test the package in a Linux system, since I'm working on FreeBSD now. I hope to count on you if I need further assistance on this subject. I'll be starting another thread if I can't solve it. Best regards, Alberto Mijares -------------- next part -------------- A non-text attachment was scrubbed...

It?s complicated to answer, but yes it is? in some situations at least? if doing video too, those need to be in sync. Using video or not you need to handle where different clock sources can be sending at slightly different rates (or have a different reference for what a rate is)? that case will give you underflow, or overflow in reference to each other.. underflow you might be able to get away with just silence for a frame or partial frame, overflow you need to do something with or a buffer will fill. There are multiple approaches to deal with this. All of the approaches end up with a balance trying to have the effect barely perceivable, but still effective. Trimming out packets that are silence (effectively shortening the silence periods) is one way for example? a much more expensive way that has even better sound results would be to insert or remove individual samples (requires some approach to keep things in phase)? On video you have similar issues where you might want to drop or ?freeze? for a frame? Lots of research on the best ways to do this. > > /Kaiduan > > > > On Wednesday, May 10, 2017 12:15 PM, Moises Silva wrote: > > > On Thu, May 4, 2017 at 1:36 PM, Michael Jerris > wrote: > you add signed linear samples together. > >> On Apr 12, 2017, at 10:05 AM, kaiduan xie > wrote: >> >> Hi, >> >> Can anyone explain how audio mixing works in Freeswitch audio conference and where is the source code? >> >> Thanks a lot in advance, >> >> /Kaiduan > > > And to be more precise and answer your second question: > > https://freeswitch.org/stash/projects/FS/repos/freeswitch/browse/src/mod/applications/mod_conference/mod_conference.c?at=f691d139eab#576 -------------- next part -------------- An HTML attachment was scrubbed...

Briefly, the issue I'm running into is that if a second station barges in on the first station, and then the first station hangs up, then the call completely hangs up. I'm trying to make something where the call keeps going, effectively replicating the old analog experience. In commit a511ff3026b8, some short 5 years ago, you implemented barging as eavesdropping. You also added code, which has largely remained unchanged, in sofia_handle_sip_i_bye which looks like it attempts to deal with the situation I describe. However it's not working. With some hacks I was able to get the second call to not hang up, but the media does not pass through to it anymore. The core issue is that other_uuid is null (which is the SWITCH_SIGNAL_BOND_VARIABLE). It may be due to the fact that I was testing this by dialing e.g. a conference application or echo application, and then joined the call - as such the original call wasn't bonded in the first place. However I think I also tested it with something more akin to a regular call and it also failed. I'm less sure of that though. Something else that I think I've observed is that if the initial station puts the call on hold, then eavesdropping (i.e. barging) station is effectively muted as well. Again, primarily testing with e.g. the echo application. Any advice you can give on these issues would be greatly appreciated! Thanks, -ilia
