34 // NOTE: this is a partial update of the Avisynth C interface to recognize
35 // new color spaces added in Avisynth 2.60. By no means is this document
36 // completely Avisynth 2.60 compliant.
37 // 170103: added new CPU constants (FMA4, AVX512xx)
38 // 171102: define SIZETMOD. do not use yet, experimental. Offsets are size_t instead of int. Affects x64.
39 // 171106: avs_get_row_size calls into avs_get_row_size_p, instead of direct field access
40 // 171106: avs_get_height calls into avs_get_row_size_p, instead of direct field access
41 // 180524: AVSC_EXPORT to dllexport in capi.h for avisynth_c_plugin_init
42 // 180524: avs_is_same_colorspace VideoInfo parameters to const
43 // 181230: Readability: functions regrouped to mix less AVSC_API and AVSC_INLINE, put together Avisynth+ specific stuff
44 // 181230: use #ifndef AVSC_NO_DECLSPEC for AVSC_INLINE functions which are calling API functions
45 // 181230: comments on avs_load_library (helper for loading API entries dynamically into a struct using AVSC_NO_DECLSPEC define)
46 // 181230: define alias AVS_FRAME_ALIGN as FRAME_ALIGN
47 // 181230: remove unused form of avs_get_rowsize and avs_get_height (kept earlier for reference)
48 // 190104: avs_load_library: smart fallback mechanism for Avisynth+ specific functions:
49 // if they are not loadable, they will work in a classic Avisynth compatible mode
50 // Example#1: e.g. avs_is_444 will call the existing avs_is_yv24 instead
51 // Example#2: avs_bits_per_component will return 8 for all colorspaces (Classic Avisynth supports only 8 bits/pixel)
52 // Thus the Avisynth+ specific API functions are safely callable even when connected to classic Avisynth DLL
