Niklas Haas	9d8f5141cf	swscale/rgb2xyz: add explicit width parameter This fixes an 11-year-old bug in the rgb2xyz functions, when used with a negative stride. The current loop bounds turned it into a no-op. Additionally, this increases performance on highly cropped images, whose stride may be substantially higher than the effective width.

Niklas Haas	6b40be941a	swscale/options: relax src/dst_h/v_chr_pos value range When dealing with 4x subsampling ratios (log2 == 2), such as can arise with 4:1:1 or 4:1:0, a value range of 512 is not enough to cover the range of possible scenarios. For example, bottom-sited chroma in 4:1:0 would require an offset of 768 (three luma rows). Simply double the limit to 1024. I don't see any place in initFilter() that would experience overflow as a result of this change, especially since get_local_pos() right-shifts it by the subsampling ratio again.	4 months ago

Niklas Haas	4ec45aca36	swscale/utils: fix leak on threaded ctx init failure This count gets incremented after init succeeds, when it should be incremented after alloc succeeds. Otherwise, we leak the context on failure. There are no negative consequences of incrementing for allocated-but-not-initialized contexts, as the only functions that reference it will, in the worst case, simply behave as if called on allocated-but-not-initialized contexts, which is in line with expected behavior when sws_init_context() fails.	6 months ago
