717c7f4ae9 avcodec/Makefile: Only compile nvenc.o if needed 
This fixes compilation errors in case nvenc is enabled
(e.g. autodected) with both nvenc-based encoders disabled
because nvenc uses ff_alloc_a53_sei(), yet only the nvenc-based
encoders require atsc_a53.
(This error does not manifest itself in case of static linking
(nothing pulls in nvenc.o), but it exists with shared builds.)

5962698d25 avcodec/av1_vaapi: setting 2 output surface for film grain

5774a0524c avcodec/vaapi: increase av1 decode pool size 
For film grain clip, vaapi_av1 decoder will cache additional 8
surfaces that will be used to store frames which apply film grain.
So increase the pool size by plus 8 to avoid leak of surface.
