Date: Sun, 12 Jul 2020 13:48:48 +0800
Subject: [PATCH] lavf/srt: fix build fail when used the libsrt 1.4.1
libsrt changed the:
SRTO_SMOOTHER -> SRTO_CONGESTION
SRTO_STRICTENC -> SRTO_ENFORCEDENCRYPTION
and removed the front of deprecated options (SRTO_SMOOTHER/SRTO_STRICTENC)
in the header, it's lead to build fail
fix #8760
