VAAPI working/passing arguments?

[kdackiw 1]

From my Emby docker I can use its ffmpeg and vaapi (backed by qsv way below) to pull frames.  Setting up the plugin for vaapi doesn't seem to inject any parameters into ffmpeg:

"[2026-05-18 18:08:41.323] [DEBUG] FFmpeg command: /bin/ffmpeg -ss 3457.168 -i <path> -vframes 1 -vf scale=320:-1 -q:v 17"

This is with the attached config.

?
