Hello, I am trying to port pjproject-2.0 beta to a specific hardware which has no SDL library for video. It is using PE instead (presentation engine) So my idea is to create new define : #define PJMEDIA_VIDEO_DEV_HAS_PE 1 and to add in videodev.c #if PJMEDIA_VIDEO_DEV_HAS_PE pjmedia_vid_dev_factory* pjmedia_pe_factory(pj_pool_factory *pf); #endif and to create pe_dev.c based on the template of sdl_dev.c So I'm trying for a start is to make PE device a dummy device, which does nothing with incoming packets. But on incoming video call from x-lite I get error like this: 04:14:28.026 pjsua_call.c .Incoming Request msg INVITE/cseq=2 (rdata0x23d62c) 04:14:28.027 pjsua_media.c ..Call 0: initializing media.. 04:14:28.029 pjsua_media.c ...RTP socket reachable at 10.10.10.43:4000 04:14:28.029 pjsua_media.c ...RTCP socket reachable at 10.10.10.43:4001 04:14:28.031 pjsua_media.c ...RTP socket reachable at 10.10.10.43:4002 04:14:28.031 pjsua_media.c ...RTCP socket reachable at 10.10.10.43:4003 04:14:28.031 pjsua_media.c ...Media index 0 selected for audio call 0 assertion "(status=pjmedia_sdp_validate(l_sdp))==0" failed: file "../src/pjsip-ua/sip_inv.c", line 970, function "pjsip_inv_verify_request3" -------------- next part -------------- An HTML attachment was scrubbed...
