Comment (by jkqxz):

 It's decoding the JPEG to vaapi/yuv420p, and that gets passed directly to
 the vp9_vaapi encoder.  The encoder agrees it supports that format, but
 then seems to fail on encode saying the surface is invalid.

 Despite what the capabilties say, maybe it doesn't support yuv420p input -
 try adding `-vf scale_vaapi=format=nv12`?
