Update:
on x64 Linux Debian system, y4m input seems working:
$ x265 charlie.y4m -o charlie.hevc
y4m [info]: 1280x720 23Hz, frames 0 - 95 of 96
x265 [info]: detected SIMD architectures SSE2 SSE3 SSSE3 SSE4.1 SSE4.2
x265 [info]: performance primitives: intrinsic assembly
x265 [info]: Main profile, Level-3.1 (Main tier)
x265 [info]: Parallelism disabled, single thread mode
x265 [info]: CU size : 64
x265 [info]: Max RQT depth inter / intra : 3 / 3
x265 [info]: ME method / range / maxmerge : star / 64 / 5

x265 [info]: enabled coding tools: rect rdo rdoq sign-hide tskip tskip-fast
rdoqts
[46.9%] 45/96 frames, 0.62 fps, 131.56 kb/s, eta 0:01:22
but yuv input still doesn't work.
$ x265 charlie.yuv -o charlie.hevc
