This can avoid out of memory with vaapi filters since commit 5fa00b3.

Example:
$ ffmpeg -init_hw_device vaapi=hw:/dev/dri/renderD128
-hwaccel_output_format vaapi -hwaccel vaapi -i input.mp4 -vf
'scale_vaapi=w=720:h=480' -vframes 1 -f null -
...
[vf#0:0 @ 0x55ffe793ba80] Error while filtering: Cannot allocate memory
