--EXPECT--
Decoding AVIF image: ok
Default AVIF encoding: ok
Encoding AVIF at quality 70: ok
Encoding AVIF at quality 70 with speed 5: ok
Encoding AVIF with default quality: ok
Encoding AVIF with illegal quality: imageavif(): Argument #3 ($quality) must be between -1 and 100
Encoding AVIF with illegal speed: imageavif(): Argument #4 ($speed) must be between -1 and 10
Encoding AVIF losslessly... ok
Decoding the AVIF we just wrote...
What is the mean squared error of the two images? 0
