      avfilter/vf_yadif_cuda: Remove unnecessary stream synchronisation · c0b6e4cb
      Philip Langdale authored 
      I put this call in by habit, rather than because there was any
actual need. The filter is simply processing frames one after
the other and has no need to synchronise.

malakudi on the devtalk forums noticed a slowdown when using nvenc
with temporal/spatial aq and that the slowdown went away if the
sync call was removed. I also verified that in the basic encoding
case there's an observable speedup.

I also verified that we aren't doing unnecessary sync calls in any
other filter.

      lavc/vaapi_h264: Do not set FMO fields. · f8fa8bbf
      Carl Eugen Hoyos authored 
      The fields are deprecated in current vaapi,
setting them to 0 in old versions is fine
as FMO is not implemented.

Fixes the following warnings:
libavcodec/vaapi_h264.c:259:10: warning: 'num_slice_groups_minus1' is deprecated [-Wdeprecated-declarations]
        .num_slice_groups_minus1                    = pps->slice_group_count - 1,
         ^

libavcodec/vaapi_h264.c:261:10: warning: 'slice_group_change_rate_minus1' is deprecated [-Wdeprecated-declarations]
