Hi all,
I'm trying to enhance an android app with video chat
capabilities, so I dove into the pjsip configuration/building
nightmare for an entire weekend... (no offense to the devs on this
project, but I don't think I've ever had such a difficult
experience building software).
After lots of fails and retries, I managed to get pjsip built
with openh264 and openssl support.
For testing purposes, I'm using two devices - an android phone
and an android tablet. Both are running pjsua2. I created two sip
accounts with iptel (which I'm using as the accounts for pjsua2).
I'm pretty psyched that I'm able to make voice calls between the
two android devices. However, video doesn't seem to be happening
yet.
I don't want to spam the list with my Android Monitor logcat output,
so I've placed it on my web server here:

The lines that seem to spell out a problem are:

Thinking it was an issue with the video codec, I spent several
hours trying to use the android ndk cross compiler to build
various versions of ffmpeg for android, and finally succeeded with
2.8.1, but the pjsip configure script never seemed to take the
prefix I supplied (--with-ffmpeg=), so I gave up and rebuilt with
only h264.
I also tried using my internal wifi (with and without SIP ALG
enabled on my router) as well as just my cell carrier (Verizon)
for network connectivity.
Please, if anyone could point me in the right direction, I'd be
extremely grateful.
