[FFmpeg-devel] [PATCH 0/4] avfilter/vf_colormatrix: add UHD support

[Thomas Mundt]

These patches add bt.2020 colorspace and 10 and 12 bit depth support.
The calculation of the Y component is simplified but with identical results.
Some unused variables are removed.
The YUV croma coefficients are calculated instead of taken from a rough rounded table.
Since these calculations happen only once the increased precision is worth it.
Please comment.
