Zhao Zhili	e18b46d95f	swscale/aarch64: Fix rgb24toyv12 only works with aligned width Since `c0666d8b`, rgb24toyv12 is broken for width non-aligned to 16. Add a simple wrapper to handle the non-aligned part. Co-authored-by: johzzy <hellojinqiang@gmail.com> Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>	2 months ago

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.	3 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.	4 months ago
Sean McGovern	34b4ca8696	swscale: prevent undefined behaviour in the PUTRGBA macro For even small values of 'asrc[x]', shifting them by 24 bits or more will cause arithmetic overflow and be caught by GCC's undefined behaviour sanitizer.

Ramiro Polla	88a402df74	swscale/yuv2rgb: fix conversion for widths not aligned to 8 The C code for some pixel formats (rgb555, rgb565, rgb444, and monob) was not converting the last pixels on widths not aligned to 8. NOTE: the last pixel for odd widths is still not converted for any of the pixel formats in the C code for yuv2rgb except for monob.	5 months ago
