The error-concealer is plugged in after any motion vectors have been decoded. It tries to estimate any missing motion vectors from the motion vectors of the previous frame. Intra blocks with missing residual are replaced with inter blocks with estimated motion vectors. This feature was developed in a separate sandbox (sandbox/holmer/error-concealment).

## This script is the front-end to the build system. It provides a similar
|
|
## interface to standard configure scripts with some extra bits for dealing
|
|
## with toolchains that differ from the standard POSIX interface and
|
|
## for extracting subsets of the source tree. In theory, reusable parts
|
|
## of this script were intended to live in build/make/configure.sh,
|
|
## but in practice, the line is pretty blurry.
|
|
##
|
|
## This build system is based in part on the FFmpeg configure script.
