(FMT is a little unclear imo.)
If you mean the colour space and the raw audio format,
then you can read AVCodecContext->pix_fmt and
AVCodecContext->sample_fmt to get the format the
decoder produced for your input.
There is no "list" because afaict it wouldn't help you:
The output format depends on the input you provide.
(There are decoders for which you can specify a
preferred output format, but this is very unusual,
primarily used to stop libavcodec from decoding alpha
planes if they aren't needed.)
