API changes, most recent first:
2024-12-05 - xxxxxxxxxx - lavu 59.48.100 - csp.h
Add av_csp_trc_func_inv_from_id().
2024-11-25 - xxxxxxxxxx - lsws 8.12.100 - swscale.h
Allow using sws_frame_scale() dynamically, without first initializing the
SwsContext. Deprecate sws_init_context(). Add sws_frame_setup() instead.
