[IIAB] IIAB Digest, Vol 17, Issue 10

[Braddock Gaskill]

Tony pretty much has it right.  The reason we transcode Khan into both mp4
and webm is that Firefox on Linux does not support mp4 (at least the last
time I checked).

If you really wanted to, you could prune the more detailed layers from the
Open Street Map data as well.  The levels of detail are in directories 0
through 15 (15 the highest detail) in
knowledge/modules/openstreetmap/mod_tile64/default

Deleting level 14 and 15 of OSM would save you 76 GB for example.  But
you'll also need to set the max layer in the javascript or else your users
will be able to zoom down to blank pages.  I can look up the parameter if
anyone is actually interested in doing this.
