[FFmpeg-devel] [PATCH v2] lavfi: add a libplacebo filter

From: Niklas Haas This filter conceptually maps the libplacebo `pl_renderer` API into libavfilter, which is a high-level image rendering API designed to work with an RGB pipeline internally. As such, there's no way to avoid e.g. chroma interpolation with this filter, although new versions of libp

[FFmpeg-devel] [PATCH] libavcodec/qsvenc: Adding support for HDR metadata to hevc qsv encode

This patch allows passing of HDR10 metadata through qsv_params for encoding with hevc_qsv similar to how HDR10 parameters are passed to x265-params in libx265 encoding. The HDR10 metadata parameters passed are master-display, max-cll, color primary, color matrix, transfer characteristics and col

The MLP/TrueHD encoder uses pointers to non-const to access several static objects that are only initialized at runtime and are therefore not declared as const. This does not result in compiler warnings, but it is fragile, as these objects are really not to be modified as they are not owned by any
