Ticket #1572 (closed defect: fixed)

Opened 6 years ago

Last modified 6 years ago

Modifying video stream in a call caused duplicate transport attributes in the SDP (thanks to Itay Bianco for the report)

Backport to 1.x milestone: Backported: no


When pjsua_vid.c's call_modify_video() is called, the current SDP will be cloned then the media transport attributes will be added to the SDP by calling pjmedia_transport_encode_sdp(). This can cause duplicate attributes if the current SDP already has media transport attributes.

To reproduce using pjsua: Enable ICE, establish a call, modify the video stream (such as "vid call rx off 1")
