I'm surprised to see such big emphasis on support for Android. Most camera modules come with their own drivers that already provide Android support. One benefit could be the licensing, but after a quick inspection it is unclear to me what license this library is under -- there is a licenses folder with 4 different licenses in addition to a developer agreement.
The design seems to be heavily inspired by the Android camera API: per-frame configuration, 3A, multiple stream support, device enumeration, etc.

That is interesting, since most camera modules will have a hardware accelerated path to encode frames directly to JPEG. If it's done internally, it will be much slower than all other implementations I'm aware of.
