* swscale/range_convert: fix mpeg ranges in yuv range conversion for non-8-bit ↵Ramiro Polla2024-12-05179-699/+751
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pixel formats There is an issue with the constants used in YUV to YUV range conversion, where the upper bound is not respected when converting to mpeg range. With this commit, the constants are calculated at runtime, depending on the bit depth. This approach also allows us to more easily understand how the constants are derived. For bit depths <= 14, the number of fixed point bits has been set to 14 for all conversions, to simplify the code. For bit depths > 14, the number of fixed points bits has been raised and set to 18, to allow for the conversion to be accurate enough for the mpeg range to be respected. The convert functions now take the conversion constants (coeff and offset) as function arguments. For bit depths <= 14, coeff is unsigned 16-bit and offset is 32-bit. For bit depths > 14, coeff is unsigned 32-bit and offset is 64-bit. x86_64: chrRangeFromJpeg8_1920_c: 2127.4 2125.0 (1.00x) chrRangeFromJpeg16_1920_c: 2325.2 2127.2 (1.09x) chrRangeToJpeg8_1920_c: 3166.9 3168.7 (1.00x) chrRangeToJpeg16_1920_c: 2152.4 3164.8 (0.68x) lumRangeFromJpeg8_1920_c: 1263.0 1302.5 (0.97x) lumRangeFromJpeg16_1920_c: 1080.5 1299.2 (0.83x) lumRangeToJpeg8_1920_c: 1886.8 2112.2 (0.89x) lumRangeToJpeg16_1920_c: 1077.0 1906.5 (0.56x) aarch64 A55: chrRangeFromJpeg8_1920_c: 28835.2 28835.6 (1.00x) chrRangeFromJpeg16_1920_c: 28839.8 32680.8 (0.88x) chrRangeToJpeg8_1920_c: 23074.7 23075.4 (1.00x) chrRangeToJpeg16_1920_c: 17318.9 24996.0 (0.69x) lumRangeFromJpeg8_1920_c: 15389.7 15384.5 (1.00x) lumRangeFromJpeg16_1920_c: 15388.2 17306.7 (0.89x) lumRangeToJpeg8_1920_c: 19227.8 19226.6 (1.00x) lumRangeToJpeg16_1920_c: 15387.0 21146.3 (0.73x) aarch64 A76: chrRangeFromJpeg8_1920_c: 6324.4 6268.1 (1.01x) chrRangeFromJpeg16_1920_c: 6339.9 11521.5 (0.55x) chrRangeToJpeg8_1920_c: 9656.0 9612.8 (1.00x) chrRangeToJpeg16_1920_c: 6340.4 11651.8 (0.54x) lumRangeFromJpeg8_1920_c: 4422.0 4420.8 (1.00x) lumRangeFromJpeg16_1920_c: 4420.9 5762.0 (0.77x) lumRangeToJpeg8_1920_c: 5949.1 5977.5 (1.00x) lumRangeToJpeg16_1920_c: 4446.8 5946.2 (0.75x) NOTE: all simd optimizations for range_convert have been disabled. they will be re-enabled when they are fixed for each architecture.

| | | | | | | | | This commit also reduces the number of times ff_sws_init_scale() gets called (only once per bit depth), and the number of times randomize_buffers() gets called (only if the function must be checked). Benchmarks are only performed on bit depths 8 and 16 (since they are different functions, and not only different constants).

* swscale: rename SwsContext to SwsInternalNiklas Haas2024-10-246-114/+138
| | | | | | | | | | | | | | | | | | | | | | | | And preserve the public SwsContext as separate name. The motivation here is that I want to turn SwsContext into a public struct, while keeping the internal implementation hidden. Additionally, I also want to be able to use multiple internal implementations, e.g. for GPU devices. This commit does not include any functional changes. For the most part, it is a simple rename. The only complications arise from the public facing API functions, which preserve their current type (and hence require an additional unwrapping step internally), and the checkasm test framework, which directly accesses SwsInternal. For consistency, the affected functions that need to maintain a distionction have generally been changed to refer to the SwsContext as *sws, and the SwsInternal as *c. In an upcoming commit, I will provide a backing definition for the public SwsContext, and update `sws_internal()` to dereference the internal struct instead of merely casting it.
