Posted: Sun Jan 29, 2017 1:47 pm"DS214play and DS415play with Intel Evansport SoC are the only models supported [for hardware transcoding]. Serviio uses the multimedia tool FFmpeg for manipulating media files, and I am only able to build a hardware-assisted FFmpeg for DS214play and DS215play. Subsequent to those products, Synology has marketed a number of other systems with hardware transcoding features but these are not supported by Serviio. The DS216play with STiH412 Monaco SoC uses a specialised build of Gstreamer for the Synology transcoding solution, so its hardware features cannot be used by FFmpeg. It seems likely that Synology is also using Gstreamer for the Intel Braswell or newer generation CPUs with QuikSync, since DSM ships with an older FFmpeg (2.7.1) than the version which introduced QuikSync support (2.8.0). To implement FFmpeg QuikSync hardware transcoding support requires Linux kernel patches for libmfx support which is not currently included in DSM 6.x, so Serviio support for Intel QuikSync on Synology is unlikely unless Synology in future switches to using FFmpeg for its own hardware transcoding solution."
