Hi All, For some special reason, I need to delay the audio play back for 1 second for both ends. I tried both snd_play_latency or snd_rec_latency in pjsua_media_config (media_config. snd_play_latency = 1000 or media_config. snd_rec_latency = 1000). However, I didn't see the latency I expected at all. Both ends still played back the audio instantly. That was good for the purpose of voice calling. But it didn't satisfy my special requirement. Could anyone share any thoughts on how I can do it? Thanks! -------------- next part -------------- An HTML attachment was scrubbed...
