2017-09-23Fix colour distortionMattias Andrée1-34/+36
This matrices are not convert to or from the proper YUV colour space both rather the ones used in videos. srgb_to_yuv was created by converting the image [sRGB(100%, 0, 0); sRGB(0, 100%, 0); sRGB(0, 0, 100%)] to YUV with FFmpeg and transposing the matrix. yuv_to_srgb is the inversion of that matrix, the values in the first column should all be 1 but are not due to rounding/truncation error.

2017-08-05Add support for skipping conversion to CIEXYZ (not complete)Mattias Andrée1-0/+25
Some tools are colour space agnostic or even encoding agnostic, by skipping conversion to CIEXYZ when these tools are used, the rendering time can be significantly reduced. The video can also be split horizontally and vertically, and latted merged back, so it is not necessary to convert the entire video if only parts of it actually need it. Because some tools are less agnostic than other tools, partial conversion to CIEXYZ is also added. blind-convert must be updated, and all tools most be test Signed-off-by: Mattias Andrée <maandree@kth.se>
