This turned out to be a very simple 2-minute sort of solution that took me a long time to figure out (two steps, read to the end).
The first step which I took was to install the pepper flash plugin (the Adobe Flash plugin is not available for Chromium), following these instructions here:
sudo apt-get install pepperflashplugin-nonfreeAfter following these instructions, I kept getting messages that the flash plugin had crashed. I tried reconflguring the pepper plugin, but that didn't help. At least some internet videos were not working, and Google Maps streetview consistently crashed.
sudo dpkg-reconfigure pepperflashplugin-nonfree

Notice that only the i386 version of Chromium is installed (bolded).
I installed chromium-browser (apt-get install chromium-browser) which replaced the i386 version. Note: this will not work on a 32-bit system.
Note which packages are uninstalled during this change. You may wish to readd the non-i386 version later.
Google Maps now works perfectly for me on Chromium.
