Have you managed to resolve this issue?
For now, not knowing any better, inserting
#define CodecID AVCodecID
somewhere near the top of ffmpeg_util.h "solved" the problem for me;
compiling succeeded, audio receiving/transmission works just fine, video
receiver and local-rendering too; and colour-stripe-pattern transmitter
as well (seeing the pattern (and the blinking dot) at remote end).
Live camera video transmission fails though.
Being new to SIP and PJSIP in particular, what I did is
pjsua --id sip:localhost --video --vcapture-dev=-1 --vrender-dev=-2
Then "vid dev list" shows
07:51:30.645 pjsua_app.c Video device list:
07:51:30.645 pjsua_app.c 3 device(s) detected:

Running on MacPro under MacOSX 10.6 and having some industrial firewire
camera attached (it only supports vga, qvga and sqvga) I changed some
settings (these seem to be codec settings but I did it in hope this
affects camera parameters too):
vid codec fps H264/97 10 1
vid codec fps H263-1998/96 10 1
vid codec size H264/97 640 480
vid codec size H263-1998/96 640 480
Finally
vid codec list
gives
07:51:55.638 pjsua_app.c Found 2 video codecs:
07:51:55.638 pjsua_app.c codec id prio fps bw(kbps) size
07:51:55.638 pjsua_app.c ------------------------------------------
07:51:55.638 pjsua_app.c H264/97 128 10.00 256/ 256 640x480
07:51:55.638 pjsua_app.c H263-1998/96 128 10.00 256/ 256 640x480
The following sceen-error-log suggests there is a problem with "preview"
window, so as next I did this:
vid dev prev off -1
vid dev prev off 0
Still without success (no camera video transmission), here is the screen
log:

and pjsua terminated.
At this point I gave up for now to look for help.
Being new to SIP technologies probably I have some misunderstandings in
basic concepts. I was looking for methods how to adjust camera
resolution and framerate in order to willfully influence transmission
bandwidth to be used (to maximise video quality at the price of smaller
frame size and lower framerate); I am thankful for any help here how to
achieve this.

P.S. The camera is OK, working just fine with every other video-chat
program under OSX (iChat, skype, xmeeting, and some less popular ones).
P.P.S. I am willing to accomplish further tests if this is helpful.
