From b2944629fafc722b5f284f9c5f739ee6fe7f0996 Mon Sep 17 00:00:00 2001 From: Ezequiel Garcia Date: Fri, 12 Oct 2018 16:11:06 -0300 Subject: [PATCH] Add support for dynamic detection of supported codecs H.264 and H.265 support is still not supported upstream, so it makes sense to autodetect each codec and only enable those that are supported.
