### Dolby Vision and hybrid
Two DV mechanisms sit on top of the track model. **DV fixup** re-exposes DV signalling on
HLS streams that carry a valid DV RPU but advertise plain HEVC (`dv_compatible_bitstream`).
HLS and DASH streams that carry a valid DV RPU but advertise plain HEVC, with DV only in the
supplemental codecs (`dv_compatible_bitstream`). `--list` shows such a track as `HDR10+DV` or `HDR10P+DV`.
**Hybrid** processing (`Video.Range.HYBRID`) selects an HDR10(+) base and a DV donor,

track that carries both HDR10 metadata and the DV RPU. Both are automatic once the
