I’m using Orange Pi Zero 3 with Ubuntu 22.04.4 on board. One-way video communication is important to me, i.e. with Orange Pi, video should go to the subscriber, and only audio back. The initiator of the communication is always the Orange Pi.

I installed pjproject-2.14.1 following the instructions. I’m using the standard pjsua application. I launch it with my configuration. I execute the video enable command vid enable, then make a call to my Android phone with SIP. An incoming call appears on the phone and three buttons are shown: reject call, answer with video, answer with audio. I click the “reply with video” button. A dark screen appears where there should be a video from Orange Pi and a small window where I see myself from the phone camera. As I understand it, the video call goes through, but for some reason the video from the Orange Pi camera does not go through. In Orange Pi I use a USB camera. Installed v4l-utils to use the camera. The camera works great. Running ./aconfigure I made sure that v4l2 is supported – checking for v4l2_open in -lv4l2... yes. Installed the H264 codec. In the config_site.h file I specified

#define PJMEDIA_HAS_VIDEO       1
#define PJMEDIA_HAS_OPENH264_CODEC      1

How do I configure pjsua so that I can make a video call from Orange Pi?

I launch pjsua with the command ./pjsua-aarch64-unknown-linux-gnu --config-file sip.conf. Configuration file sip.conf:

--id sip:[email protected]
--registrar sip:172.16.35.30
--realm *
--username 1003
--password PASSWORD

When running pjsua and executing the vid commands I can see the following:
