export LIBVA_FOOL_POSTP=1
Unfortunately, it is not handled in x11/va_x11.c: vaPutSurface
We may need similar codes as android/va_androi.c:vaPutSurface for
va_x11.c:vaPutSurface
if (fool_postp)
return VA_STATUS_SUCCESS;
Thanks

Maybe the getenv("INTEL_DECODE_BENCH") will cost some time as it searches env
list. But compared with the time of rendering/decoding operation, the cost time
can almost be ignored.
