If you have a CUDA graphics card you can try VideoStitch
Depending on graphics card and output size can run at real time.
http://www.video-stitch.com/
It uses Hugin file for templates and aligning images.
The trial version will produce non watermarked output up to 1000 pixels wide. or
watermarked over 1000 pixels wide. If you have lots of images to process the
purchase price may well be worth it.

I've used Bruno's approach and it works very well--but I'm wondering if
there's a way to speed this up?
Right now, I'm using a shell script to invoke nona and enblend, as Bruno
suggests, in a loop for each set of frames from my video cameras. But it's
pretty slow, as I spin up and release a new nona and enblend process for every
frame.
Is there a way to do this more efficiently?
Thanks!

These are instructions for aligning and stitching a pair of photos
on the command-line, but for stitching a video stream you only need
to align one pair of photos in the Hugin GUI and use this .pto
project as a template to stitch all the others.
Once you have a .pto project as a template, you can use it to
process any other pair of similar images like so:
nona -o temp template.pto left0123.jpg right0123.jpg
This creates two remapped images, called temp0001.tif and
temp0002.tif. You can join them together with enblend:
enblend --no-optimize -o 0123.jpg temp0001.tif temp0002.tif
The result is a single joined frame called 0123.jpg
Hope this helps, note that the same process should work for more
than two cameras.
