commit b98751b13c7295765ba212ecb0c23a213c6d3a2d Author: Niklas Haas <[email protected]> AuthorDate: Tue Feb 10 18:18:09 2026 +0100 Commit: Niklas Haas <[email protected]> CommitDate: Mon Feb 23 19:39:17 2026 +0000 swscale/graph: set up palette using current input image Using the original input image here is completely wrong - the format/palette could have been set to anything else in the meantime. At best, we would want to use the original input to add_legacy_sws_pass(), but it's impossible for this to differ from the per-pass input. The only time legacy subpasses are added is when using cascaded contexts, but in this case, the only context actually reading from the palette format would be the first one. I'm not entirely sure why this code was originally written this way, but I'm reasonably confident that it's not at all necessary. Tested extensively on both FATE, the self-test, and real-world files.
