Comment (by Gyan):
Since x265 now supports alpha layer, it advertises yuva420p as a supported
pixel format, and the overlay filter will select that automatically.
So, when either input to overlay has alpha, add `format=yuv420p` after
overlay when using libx265
`-filter_complex [0:v][0:s:0]overlay,format=yuv420p`
