- Modified the calculation of `dw` to use `FFALIGN(sw, 32)` instead of `sw >> 2 << 2`. - Ensured that the destination width is aligned to a multiple of 32, which improves compatibility with hardware decoders (e.g., h264_cuvid). - This change resolves potential crashes caused by misaligned resolutions when using `sws_scale`. Related logs: - Original resolution (888x550) caused crashes due to unaligned width. - After alignment, the issue was resolved and the program runs stably."
