Summary of the bug:
I am trying to produce a dash format video with two different video
codecs; one being av1 and the other being h264. However, it seems as
though libsvtav1 is attempting to parse the parameters for libx264 and
preventing the command from running.
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.
