Not sure about other containers, are the specs for those even finalized?

For the options, it doesn't work like x264 or the likes, you can't just pass arbitrary option strings to the library to parse.
Currently, the following options are available directly, plus the usual ffmpeg options for bitrate etc:
-cpu-used x
-auto-alt-ref x
-lag-in-frames x
-error-resilience {default|partitions}
-crf x
-static-thresh x
-drop-threshold x
-noise-sensitivity x
Thanks.

It would make sense for FFMPEG to be able pass AV1 specific encoder parameters to libaom just like you can with -x264-params or -x265-params.
