Hi,PJSIPer. Right now We are do a SIP communication between two hardware ARM SOC board.But for pjsip,there are a lot of software processing,for example,audio encode,audio decode,video encode,video decode.But we wanna use our Soc's hardware audio/video codec to perform these work.If so,how we do the interface modify?Is there some guideline or doc? I know it is a big topic,be happy to receive any reply. BR~ -- suitjune
