[FFmpeg-devel] [PATCH] vulkan_av1: Set force_integer_mv on intra frames

[Mark Thompson <sw@jkqxz.net>]

The flag in CBS is the value read from the bitstream (as required for
passthrough), but the specification overrides that by setting it
immediately after reading if the frame is intra.

This is already done for DXVA and VDPAU.  Also wondering whether this should be done for VAAPI?
