Encoding Discussion Megathread (ffmpeg, Handbrake, AV1, etc...)

Interesting. I get files that are exactly the same size but different check sums.

My script's ffmpeg command

Code:

ffmpeg \
                -init_hw_device vaapi=va:,driver=iHD,kernel_driver=i915 -y -hide_banner -stats -fflags genpts -loglevel error \
                -init_hw_device qsv=qs@va \
                -filter_hw_device qs \
                -hwaccel qsv \
                -hwaccel_output_format qsv \
                -i "$INPUTFILE" \
                $INPUT_LIST \
                -ss $startTime \
                -to $endTime \
                -map_chapters 0 \
                $MAPPING \
                -c:v av1_qsv \
                -preset veryslow \
                -vf vpp_qsv="$FILTERS" \
                -c:a copy \
                -c:s copy \
                -disposition:s 0 \
                -global_quality:v 26 \
                -look_ahead 1 \
                -look_ahead_depth 100 \
                "$outputFile"

All I did was add -low_delay_brc 1 -extbrc 1.
