...ly here is how I am setting up my encoder: int size = opus_encoder_get_size(1); sOpusEnc = Memory_alloc(OpusHeap,size,NULL,NULL); // // sOpusEnc = opus_encoder_create(16000, // 1, // OPUS_APPLICATION_VOIP, &i32error); i32error = opus_encoder_init(sOpusEnc, 16000, 1, OPUS_APPLICATION_RESTRICTED_LOWDELAY); opus_encoder_ctl(sOpusEnc, OPUS_SET_BITRATE(16000)); opus_encoder_ctl(sOpusEnc, OPUS_SET_VBR(1)); opus_encoder_ctl(sOpusEnc, OPUS_SET_VBR_CONSTRAINT(0)); opus_encoder_ctl(sOpusEnc,...

Jean-Marc, Thanks for the response and the helpful info. I am trying to get the library to build without using the pseudostack define, and use either VAR_ARRAYS or ALLOC, but it seems the global stack is not defined. Where do can I define this in my example? VR -----Original Message----- From: Jean-Marc Valin [mailto:jmvalin at jmvalin.ca] Sent: Tuesday, February 20, 2018 5:40 PM To:
