Hello Benny,
I use /pjsua_media_config_default/ function to initialize
/pjsua_media_config.
/ audio_frame_ptime = PJSUA_DEFAULT_AUDIO_FRAME_PTIME = 20;
ec_tail_len = PJSUA_DEFAULT_EC_TAIL_LEN = 200;
snd_auto_close_time = 0;
ptime = 0;/
/
You are right, ptime is lower than 10ms, but I never defined before this
field and it worked.
where ptime is defined ?
Thanks
Samuel
