[FFmpeg-devel] [PATCH] lavc/vaapi_encode_av1: Fix ref_order_hint value for second slot

[David Rosca <nowrep@gmail.com>]

We always use two slots, even when only one L0 reference is supported
by the driver. However we still need to set the correct value for the
ref_order_hint of the second slot.

Fixes bf9f921ef7 ("avcodec/hw_base_encode: restrict size of next_prev")
