Comment:
You can specify the encoder you want to use (although it can fallback to other encoders).
https://github.com/AOMediaCodec/libavif/blob/647c3c208cf152395d777c1bf7240d2ecf7df5a9/include/avif/avif.h#L707-L715

For example, the kimageformats test fails if you don't provide libaom since ra1ve and libsvt-av1 provide a different binary output (and don't support lossless).

libaom is the most important since it is necessary for lossless, rav1e and libsvt-av1 are faster and enabling them allow people to use them through libavif.
