[FFmpeg-devel] [PATCH 1/2] lavfi/vf_libplacebo: switch to new pl_options struct
Niklas Haas
ffmpeg at haasn.xyz
Fri Aug 18 19:50:04 EEST 2023
From: Niklas Haas <git at haasn.dev>
This new upstream struct simplifies params struct management by allowing
them to all be contained in a single dynamically allocated struct. This
commit switches to the new API in a backwards-compatible way.
The only nontrivial change that was required was to handle
`sigmoid_params` in a way consistent with the rest of the params
structs, instead of setting it directly to the upstream default.
