Convert file to AV1 using hw accel.

Had to look back at my script to see what I'm forgetting. Forgot to initialize the driver.

Code:

-init_hw_device vaapi=va:,driver=iHD,kernel_driver=i915

Code:

/usr/lib/jellyfin-ffmpeg/ffmpeg -fflags +nobuffer+discardcorrupt+genpts+flush_packets -init_hw_device vaapi=va:,driver=iHD,kernel_driver=i915 -init_hw_device qsv=qs@va -filter_hw_device qs -hwaccel qsv -hwaccel_output_format qsv -extra_hw_frames 40 -i ballon.1080p.mkv -c:v av1_qsv -preset veryslow -extbrc 1 -low_delay_brc 1 -look_ahead_depth 40 -b:v 1M -bufsize 2M -rc_init_occupancy 512K -adaptive_i 1 -adaptive_b 1 -b_strategy 1 -bf 7 -map 0:a? -c:a copy -map 0:s? -c:s copy -max_muxing_queue_size 2048 -max_interleave_delta 0 -avoid_negative_ts disabled ballon.av1.mkv
