2022-08-11Fix d881836379172f4072ed81ea074f46b3a363a681 which removed clearingCarl Hetherington
of the left-hand-side of images.
2022-08-09Fix lines down the right-hand-side of exports in some cases.Carl Hetherington
2022-06-10Fix incorrect burnt-in subtitle colours when burning into a DCP source (#2261).Carl Hetherington
dcp::combined_rgb_to_xyz was changed in libdcp (the values are no longer scaled by 65535) but DoM wasn't changed, and there was no test to catch it.
2022-05-05Update for change to libdcp API.Carl Hetherington

2021-09-27Support subs and tidy up a few things.Carl Hetherington
2021-05-25Move video level conversion for RGB from FFmpegImageProxy to Image.Carl Hetherington
Since FFmpeg does not do video level conversion for RGB sources when we (sort of) ask it to in Image::crop_scale_window() it seems to make more sense to compensate for that by calling full_to_video_range() in the same place (rather than in FFmpegImageProxy).
2021-05-25Add video_to_full_range implementation for RGB48LE.Carl Hetherington
2021-05-25Clamp results correctly when shifting video levels, and account for that in ↵Carl Hetherington

Remainder of fix for #1984.
2021-05-03Add pixel format 66 (AV_PIX_FMT_YUV422P10LE) to make_part_black().Carl Hetherington
Part of fix for #1984.

2020-11-25Fix corrupted image when over-cropping black filler frames.Carl Hetherington
FFmpegDecoder can emit small black frames (128x128 pixels) when it wants to fill in a gap. Image::crop_scale_window would do the wrong thing if we then applied a crop of greater than 128 in either direction; though cropped_size is correctly clamped, the crop value itself was not and is used to calculate the input data pointers. This would result in random frames, usually at the end of DCPs, often made up of blurry colour washes.
2020-11-17Fix cropping of subsampled images.Carl Hetherington
The calculations for how to crop subsampled components of YUV images were wrong, causing strange effects like misregistration of colour components in cropped images. Should fix #1872.
2020-11-17Add some lrintf() calls to be sure.Carl Hetherington
2020-11-17Use 64-byte alignment for aligned image memory.Carl Hetherington
FFmpeg uses this values if AVX512 is available, and with only 32-byte alignment I am seeing strange scaling effects whereby crop_scale_window_test7 gives black bars down the right side of cropped images (when run on an i7 7700).
2020-11-16Make sure we use limited ("video") range data when exporting.Carl Hetherington
Our export formats all currently use limited range but we weren't making sure data fed to the encoders was limited range. Should fix #1832.
2020-11-16Remove pointless comment.Carl Hetherington
