[FFmpeg-devel] [PATCH v4 0/4] swscale: rgbaf32 input/output support

[mindmark@gmail.com]

From: Mark Reid <mindmark@gmail.com>

This patch series adds swscale input/output support for the packed rgb float formats.
A few of the filters also needed support the larger 96/128 bit packed pixel sizes.

I also plan to eventually add lossless unscaled conversions between the planer and packed formats.

changes since v3
* removed half uv path implementation
changes since v2
* add bias to rgbaf32 output to improve non overflowing range
changes since v1
* output correct alpha if src doesn't have alpha

Mark Reid (4):
  swscale/input: add rgbaf32 input support
  avfilter/vf_hflip: add support for packed rgb float formats
  avfilter/vf_transpose: add support for packed rgb float formats
  swscale/output: add rgbaf32 output support
