It seems vlc-2.1.6 does not provide x265 and gstreamer1 support yet, 
quoting from the vlc-git NEWS file:

Changes between 2.1.6 and 2.2.0:
* Added TLS support for ftp access and sout access
New schemes for implicit (ftps) and explicit (ftpes) modes
* Support for HEVC/H.265 encoding using x265

Confirmed with local compile of 2.1.6, however libssh2 is indeed in 
vlc-2.1.6, my apologies for reporting that late in the conversation... I 
agree with your decision of reverting to a version fully compatible with 

Thanks for your work
