There are two reasons for this: 1. slice parameters control doesn't provide enough information 2. bug in frame list construction in Cedrus driver As described in commit message in patch 1, references stored in reference lists should tell if reference targets top or bottom field. However, this information is currently not provided. Patch 1 adds it in form of flags which are set for each reference. Patch 2 then uses those flags in Cedrus driver. Frame list construction is fixed in patch 3. This solution was extensively tested using Kodi on LibreELEC with A64, H3, H5 and H6 SoCs in slightly different form (flags were transmitted in MSB bits in index). Note: I'm not 100% sure if flags for both, top and bottom fields are needed. Any input here would be welcome. Please take a look.
