* avcodec/tiff_data: Avoid relocations for TiffGeoTagNameTypeAndreas Rheinhardt2024-03-141-5/+0
| | | | | | | | | | | | | | | Instead store all the strings in one continugous string (with internal \0) and use offsets to access the actual substrings. This replaces the pointers to the strings and therefore avoids relocations (and on x64, it actually shrinks TiffGeoTagNameType by reusing padding to store the offset field). This saves 720B of .data.rel.ro and 1080B of .rela.dyn (containing the relocation records) here while increasing .rodata by 384B. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* lavc/tiff: Decode embedded JPEGs in DNG imagesNick Renieris2019-09-021-0/+2
| | | | | | | | | | | | | | | | 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 [1]: As specified in the DNG Specification - Chapter 5 Signed-off-by: Nick Renieris <velocityra@gmail.com>
* avcodec/tiff: Recognize DNG/CinemaDNG imagesNick Renieris2019-05-301-5/+31
| | | | | | | | | | | | Additionally: - Renamed TIFF_WHITE_LEVEL to DNG_WHITE_LEVEL since it is specified in the DNG spec. - Added/changed some comments to be more precise in differentiating between TIFF, TIFF/EP and DNG values.
