Michael Niedermayer	4ea87c0f73	avcodec/kbdwin: Use av_bessel_i0() Old code used about 7 times as many cpu cycles as new Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	1 year ago
Michael Niedermayer	0c7a0514e3	avfilter/window_func: Use av_bessel_i0() Old code needed about 6 times as long as new with defaults in afftfilt Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	1 year ago
Michael Niedermayer	1e9c337e0f	avfilter/asrc_sinc: Use av_bessel_i0() The new function is much more precise For default beta it is slightly slower, but its speed is already at the worst case in that comparison while the replaced function becomes much slower for larger beta Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	1 year ago
Michael Niedermayer	75918016ab	Move bessel_i0() from swresample/resample to avutil/mathematics 0th order modified bessel function of the first kind are used in multiple places, lets avoid having 3+ different implementations I picked this one as its accurate and quite fast, it can be replaced if a better one is found Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	1 year ago

Lynne	f701f088f4	vulkan_h264: reject end_frame being called without valid session parameters When seeking through MBAFF-coded H264, this can happen. Decoding calls end_frame without calling start_frame. We are unable to decode this, as no frame state has been set. Happens for both VAAPI and Vulkan. Could be an issue elsewhere, hence the individual commit.	1 year ago

Dave Airlie	e49b8b48cd	av1: set skip mode frames properly There are circumstances where the flag isn't set but the skip mode frames are. So don't use the inferred bit which has other inputs when deciding to pass the skip mode frames to the device. This fixes some decoding bugs on intel av1	1 year ago

Lynne	33fc919bb7	hwcontext_vulkan: remove duplicate code, port to use generic vulkan utils The temporary AVFrame on staack enables us to use the common dependency/dispatch code in prepare_frame(). The prepare_frame() function is used for both frame initialization and frame import/export queue family transfer operations. In the former case, no AVFrame exists yet, so, as this is purely libavutil code, we create a temporary frame on stack. Otherwise, we'd need to allocate multiple frames somewhere, one for each possible command buffer dispatch.	1 year ago
Lynne	94e17a63a4	hwcontext_vulkan: don't change properties if prepare_frame fails	1 year ago
Lynne	32fc36ee61	hwcontext_vulkan: remove linear+host_visible "fast" path The idea was that it's faster to map linear images and copy them via regular memcpy. This is a very niche use, plus very inconsistently useful, as it would only really be faster on a few Intel GPUs. Even then, using the non-cached memcpy would've been better. Instead, scrap this code. Drivers are better at figuring out what copy to use, and if we're host-mapping, it should actually be just as fast, if not faster.	1 year ago
Lynne	48f85de0e7	hwcontext_vulkan: rewrite to support multiplane surfaces This commit adds proper handling of multiplane images throughout all of the hwcontext code. To avoid breakage of individual components, the change is performed as a single commit.	1 year ago

Lynne	b5eaeb1f13	vulkan: rewrite to support all necessary features This commit rewrites the majority of vulkan.c to enable its use as a general-purpose high-level utility code, usable for decoding, encoding, and filtering of video frames. The dependency system was rewritten to simplify management of execution. The image handling system was rewritten to accomodate multiplane images. Due to how related all the new features were, this is a single commit.	1 year ago
