* libavfilter/vf_colorspace.c: fix demarcation point of gamma linearize functionYonglin Luo2019-07-03
| | | | | | | | | | | | | | | | The linearize function (usually refered to EOTF) is the inverse of delinearize function (usually referred to OETF). Demarcation point of EOTF should be beta*delta, but the actual value used now in the source code is beta. For ITU Rec.709, they are 0.081 (0.018*4.5) and 0.018 respectively (beta = 0.018 and delta = 4.5), and they correspond to pixel value 5 and 21 for an 8-bit image. Linearized result of pixel within that range (5-21) will be different, but this commit will make linearize function of the filter more accurate in the mathematical sense.

* vf_colorspace: Allow overriding input color propertiesVittorio Giovara2016-09-04
| | | | | | | | | | The filter needs input frames with color properties filled out by the decoder. Since this is not always possible, add input options to the filter so that user may override color space, color primaries, transfer characteristics, and color range, as well as a generic option to set all properties at once.

* vf_colorspace: Add support for full range yuvVittorio Giovara2016-08-27
| | | | | | | | | | | | | | | Whenever a full range video is input, since the YUVJ* formats are not listed as supported for this filter, a range reduction takes place through the auto-inserted format filter, forcing the conversion to operate on a limited range, However the filter handles full range videos perfectly fine, so adding support to YUVJ* formats will allow skipping a conversion step, while providing completely identical results.

* vf_colorspace: don't enable passthrough if bitdepth doesn't match.Ronald S. Bultje2016-05-10
| | | | | | | Also check return value of av_frame_copy() in passthrough mode, so that if a copy fails (as it did here, because bitdepth didn't match), the filter doesn't return success, which would mean sending an uninitialized framebuffer further down the filtergraph.

The intent here is similar to colormatrix, but it's LGPLv2.1-or-later (instead of GPLv2.0) and supports gamma/chromaticity correction.
