PJSIP is a free and open source multimedia communication library written in C. PJSIP versions 2.12 and prior do not pars

PJSIP is a free and open source multimedia communication library written in C. PJSIP versions 2.12 and prior do not parse incoming RTCP feedback RPSI (Reference Picture Selection Indication) packet, but any app that directly uses pjmedia_rtcp_fb_parse_rpsi() will be affected. A patch is available in the master branch of the pjsip/pjproject GitHub repository.

There are currently no known workarounds.
