Niklas Haas	6ad839ff2e	avfilter/vf_scale_*: add enum names for force_oar magic values	2025-09-30 15:39:39 +00:00
Gyan Doshi	a28dc06869	avfilter/scale*: add option reset_sar ... For anamorphic videos, enabling this option leads to adjustment of output dimensions to obtain square pixels when the user requests proportional scaling through either of the w/h expressions or force_original_aspect_ratio. Output SAR is always reset to 1. Option added to scale, scale_cuda, scale_npp & scale_vaapi. libplacebo already has a similar option with different semantics, scale_vt and scale_vulkan don't implement force_oar, so for these three filters, I've made minimal changes needed to not break building or change output.	2025-02-10 16:25:23 +05:30

Tristan Schmelcher	179830108d	avfilter/scale_eval: Reduce rounding error. ... When force_original_aspect_ratio and force_divisible_by are both used, dimensions are now rounded to the nearest allowed multiple of force_divisible_by rather than first rounding to the nearest integer and then rounding in a static direction. This results in less distortion of the aspect ratio.

Gyan Doshi	e73688eff4	avfilter: rename scale.c,h to scale_eval ... scale.c is too generic; scale_eval is more representative	2019-12-10 12:55:48 +05:30
