Some example DNGs before/after the gamma correction: https://i.imgur.com/m3Qgrwb.jpg https://i.imgur.com/XgggT2h.jpg These are not full size of course, just screenshots. Colors are wrong and I'm pretty sure I know why, that's TODO. Στις Τετ, 24 Ιουλ 2019 στις 12:04 μ.μ., ο/η Nick Renieris έγραψ

I have a small patch for basic gamma correction, it makes the dark images look much better. Should I send it here (if so, just as a single email reply to this?) or wait until this patchset is merged? ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org h

[FFmpeg-devel] [PATCH v3 2/2] lavc/tiff: Decode embedded JPEGs in DNG images

2019-07-23 Thread velocityra
From: Nick Renieris Used a technique similar to lavc/tdsc.c for invoking the MJPEG decoder. This commit adds support for: - DNG tiles - DNG tile huffman lossless JPEG decoding - DNG 8-bpp ("packed" as dcraw calls it) decoding - DNG color scaling [1] - LinearizationTable tag - BlackLevel tag
