+libyuv is an open source project that includes YUV
+scaling and conversion functionality.It can be used
+to convert to YUV from webcam formats for compression.
+It can convert to RGB formats for rendering/effects.
+Rotate by 90/180/270 degrees to adjust for mobile 
+devices in portrait mode.
+
+Note:
+We are downloading from Debian because googlesource
+keeps modifying its md5sum everytime resulting in
+md5sum error.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
