Anton Khirnov	d6fdc78e91	sws: implement slice threading	3 years ago
Anton Khirnov	42cd64c182	sws: add a new scaling API	3 years ago
Michael Niedermayer	fa1e158ef6	swscale/utils: Use full chroma interpolation for rgb4/8 and dither none Dither none is only implemented in full chroma interpolation for these rgb formats Its also a obscure choice (producing less nice images) that implementing it in the other code-paths makes no sense Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	3 years ago
Anton Khirnov	1f80789bf7	sws: rename SwsContext.swscale to convert_unscaled That function pointer is now used only for unscaled conversion.	3 years ago
Anton Khirnov	fe490ec165	sws: separate the calls to scaled vs unscaled conversion Call the scaler function directly rather than through a function pointer. Drop the now-unused return value from ff_getSwsFunc() and rename the function to reflect its new role. This will be useful in the following commits, where it will become important that the amount of output is different for scaled vs unscaled case.	3 years ago
Anton Khirnov	0f8e0957d2	sws: do not reallocate scratch buffers for each slice	3 years ago
Peter Lundblad	da0abbbb01	libswscale: Make sws_init_context thread safe. Call ff_sws_rgb2rgb_init via ff_thread_once instead of checking one of the variables it updates. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	3 years ago
Andreas Rheinhardt	ea2d9b7a2e	libswscale: Remove unused deprecated functions, make used ones static Deprecated in `3b905b9fe6`. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com> Signed-off-by: James Almer <jamrial@gmail.com>	4 years ago
Jan Ekström	7ea4bcff7b	swscale/utils: override forced-zero formats back to full range Fixes vf_scale outputting RGB AVFrames with limited range flagged in case either input or output specifically sets the range. This is the reverse of the logic utilized for RGB and PAL8 content in sws_setColorspaceDetails.	4 years ago
Jan Ekström	3fe24fe232	swscale/utils: split range override check into its own function	4 years ago
Paul B Mahol	9d58cdb4ba	swscale: do not drop half of bits from 16bit bayer formats	4 years ago

Mark Reid	fabeef22d9	libswscale: fix for floating point formats, require full chroma upon more floating point testing, looks like I missed adding this bit. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	5 years ago

Linjie Fu	d2aa1fbfd4	swscale: Add swscale input support for Y210LE Add swscale input support for Y210LE, output support and fate test could be added later if there is requirement for software CSC to this packed format. Signed-off-by: Linjie Fu <linjie.fu@intel.com>	5 years ago
Gautam Ramakrishnan	da399e2135	libswscale/utils.c: Fix bug #8255 Bug #8255 points out a double free error in libwscale/utils.c file. The double free is because the pointer to cascaded_context of an sw_context is not set to NULL after freeing it. When the sw_context is later freed, sws_freeContext is called on the cascaded_context, causing a double free. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	5 years ago
Carl Eugen Hoyos	96fab29e96	Silence "string-plus-int" warning shown by clang. libswscale/utils.c:89:42: warning: adding 'unsigned long' to a string does not append to the string [-Wstring-plus-int]	5 years ago

Philip Langdale	cd48318035	swscale: Add support for NV24 and NV42 The implementation is pretty straight-forward. Most of the existing NV12 codepaths work regardless of subsampling and are re-used as is. Where necessary I wrote the slightly different NV24 versions. Finally, the one thing that confused me for a long time was the asm specific x86 path that did an explicit exclusion check for NV12. I replaced that with a semi-planar check and also updated the equivalent PPC code, which Lauri kindly checked.	6 years ago

Philip Langdale	9d5aff09a7	swscale: Add p016 output support and generalise yuv420p1x to p010 To make the best use of existing code, I generalised the wrapper that currently does yuv420p10 to p010 to support any mixture of input and output sizes between 10 and 16 bits. This had the side effect of yielding a working code path for all yuv420p1x formats to p01x.	7 years ago
