IIRC, Intel deprecated OpenCL support for Linux kernel 4.4.X. Which is the Linux kernel that a lot of Synology NASes are still using. Since it tone mapping, which uses OpenCL, when it is HWA decoding that is likely the source of the failure.
The only solution is to turn off hardware accelerated decoding for trickplays, but you can leave HWA trickplay encoding enabled.
