As a follow-up...
I took the advice and built ffmpeg from source (which takes several hours
on the Raspberry Pi). I then used the native camera command to pipe
through ffmpeg as follows:
raspivid -t 0 -w 960 -h 540 -fps 25 -b 500000 -o - | /usr/local/bin/ffmpeg
-i - -vcodec copy -an -metadata title="Streaming from raspberry pi camera"
-f flv [ustream-url]/[ustream-key]
This has been running for 24 hours. The key is the -t 0 which tells the pi
camera command to stream forever.
