From d3686003e034469b7a18fb0dc3603eb74d09481c Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sun, 17 Jul 2016 12:13:21 -0300 Subject: [PATCH] [media] doc-rst: Fix format of avermedia.rst This file is almost at the ReST format, but some things need to be fixed for it to be parsed. Also, the documentation there is old. So, add a notice about that.
