 Summary of the bug:
 How to reproduce:
 {{{
 ffmpeg -v 9 -loglevel 99 -report -i ./input.mp4 \
     -map 0:v -s:v:0 1920x1080 -c:v:0 libsvtav1 -preset 6 -crf 30 -b:v:0 6M
 -maxrate:v:0 6M -bufsize:v:0 12M \
     -map 0:v -s:v:1 1920x1080 -c:v:1 libx264 -preset slow -crf 23 -b:v:1
 6M -maxrate:v:1 6M -bufsize:v:1 12M \
     -map 0:a -c:a:0 libopus -b:a:0 320k \
     -map 0:a -c:a:1 aac -b:a:1 320k \
     -use_timeline 1 -use_template 1 \
     -f dash chunks/output.mpd
 }}}
 The main issue is this error
 {{{
 [libsvtav1 @ 0x5643ecca2ec0] [Eval @ 0x7ffe41354010] Undefined constant or
 missing '(' in 'slow'
 [libsvtav1 @ 0x5643ecca2ec0] Unable to parse option value "slow"
 [libsvtav1 @ 0x5643ecca2ec0] Error setting option preset to value slow.
 }}}
 where the libsvtav1 encoder is trying to parse the preset set for libx264.
 I attached the full output log of the command.
