Like you said, currently only libaom-av1 is available as an AV1 encoder in Shana. Other AV1 encoders like librav1e and libsvtav1 are not included in the ffmpeg library.
Including them amounts to a feature request. Let's see if @Rina is interested in it.
That said, I'm not sure if SVT-AV1(libsvtav1) is more efficient and effective in AV1 encoding than AOMEnc(libaom-av1) in general. Just out of curiosity, can you provide any concrete benchmarking results?
