Michael Niedermayer	7874d40f10	swscale/slice: Fix wrong return on error Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	4 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>	4 years ago
Michael Niedermayer	7528532550	swscale/output: Implement dither none for yuv2rgb_write_full() Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	4 years ago
Michael Niedermayer	997f9cfc12	swscale/slice: Check slice for allocation failure Fixes: null pointer dereference Fixes: alloc_slice.mp4 Found-by: Rafael Dutra <rafael.dutra@cispa.de> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	4 years ago
Anton Khirnov	37c0fe49b7	sws: move updating the palette higher up It does not interact in any way with the code setting up the image pointers/strides, so it should not be intermixed with it.	4 years ago
Anton Khirnov	d6649d9a3b	sws: move initializing dither_error higher up It does not interact in any way with the code setting up the image pointers/strides, so it should not be intermixed with it.	4 years ago
Anton Khirnov	e188985598	sws: move the early return for zero-sized slices higher up Place it right after the input parameter validation. There is no point in performing any setup if the sws_scale() call won't do anything.	4 years ago
Anton Khirnov	a91e6c927e	sws: simplify setting sliceDir	4 years ago
Anton Khirnov	ff753f41dd	sws: merge handling frame start into a single block Also, return an error code on failure rather than 0.	4 years ago
Anton Khirnov	1b11a324fe	sws: make checking for the start of a new frame more explicit	4 years ago
Anton Khirnov	0fb014b7bb	sws: reset sliceDir at the end of sws_scale() Makes it more clear that resetting it does not interact with the scaling code that it is currently intermixed with.	4 years ago
Anton Khirnov	1f80789bf7	sws: rename SwsContext.swscale to convert_unscaled That function pointer is now used only for unscaled conversion.	4 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.	4 years ago
Anton Khirnov	0f8e0957d2	sws: do not reallocate scratch buffers for each slice	4 years ago
Anton Khirnov	2730639259	sws: group the parameters validity checks together Also, fail with an error code rather than 0.	4 years ago

Anton Khirnov	f8c21ccbfc	sws: remove unnecessary braces There used to be more code inside them, but it was removed in `6de58b4903`.	4 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>	4 years ago
Limin Wang	43295ae6a9	swscale/swscale_unscaled: don't use the optimized bgr24toYV12 unscaled conversion when width%2 Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Limin Wang <lance.lmwang@gmail.com>	4 years ago

Andreas Rheinhardt	f3c197b129	Include attributes.h directly Some files currently rely on libavutil/cpu.h to include it for them; yet said file won't use include it any more after the currently deprecated functions are removed, so include attributes.h directly.

Andreas Rheinhardt	c23a5523b5	swscale/x86/swscale: Remove unused ASM constants The last user of g15Mask, r15Mask, g16Mask and r16Mask was disabled in `77a416e8aa` and finally removed in 36e8de07ed62609df45d064b56501e3084d25723; b15Mask and b16Mask were apparently always unused (except for in_asm_used_var_warning_killer, a function that only existed to make the compiler not optimize ASM constants away). w10 is unused since `d604bab901`, w02 since `ef423a6618`.

Andriy Gelman	1200264fc4	swscale/rgb2rgb_template: use shuffle macro on big-endian arches Fixes fate-qtrle-32bit on big-endian. The macro does a simple byte swap on uint8 array without any casts, so it's valid on big-endian arches. The mentioned test was failing because the byteswap function shuffle_bytes_3210_c() is used in the pixel format conversion (argb->bgra).
