demuxers in this build

Stoic builds its actual Open-panel catalog at runtime from the FFmpeg demuxers compiled into it. This page groups the formats people ask about; it does not replace that build-derived list. H.266/VVC is present in the decoder and demuxer tables but remains unverified until a real file passes the end-to-end test.
