Description

Hi, I want ask a question:
Can ffmpeg send and receive at ONE port at same time? For example : given a port number 12345. ffmpeg listen at this port to receive video and send video using this port. At window pc, if I send by ffmpeg using this port , I cannot start another ffmpeg instance to receive because this port is occupied by prior ffmpeg instance. But in a SIP RTP session, I need receive and send video use same port, so can I do this in ffmpeg (or javacv)?

Contributor guide

Research direction
Investigate if ffmpeg can simultaneously send and receive RTP streams on the same port using a single instance, and how SIP sessions handle this.
