+AOMedia Video 1 (AV1) is an Open Source video codec desgined for
+video transmission over the Internet. AV1 is planned to surpass
+VP9 and also to eventually be a competitor with HEVC/H.265.
+
+This libaom SlackBuild builds two applications:
+
+  1. aomenc: an AV1 encoder
+  2. aomdec: an AV1 decoder
+
+As well as making libraries available for those who wish to build
+an AV1 encoder with a recent FFmpeg by specifying: '--enable-libaom'
+in the FFmpeg ./configure string.

+# 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.
