we use PJSIP to develop a voip application in android OS. PJSIP use opensl to capture voice pcm data when recording. Now I meet a problem: opensl works well(there is no error report when call opensl API), but captured voice data is all zero data.
I want to know in which case this will happen. Can you help me?
BTW, where can I get opensl es source code? Maybe I can not get it. I think the source code can help me fix this issue.
Thanks a lot!
