Lynne	2c3315b04c	lavc/vulkan/common: sign-ify lengths ... This makes left_bits return useful data rather than overflowing, and also saves some 64-bit integer operations, which is still always a plus sadly.	2025-08-05 23:51:21 +09:00
Lynne	7b45d9c5fd	vulkan_ffv1: pipe through slice decoding status	2025-05-20 19:53:02 +09:00
Lynne	4d561e6a1e	vulkan_ffv1: remove need for scratch data during setup ... This saves on some VRAM, but mainly allows for a more unified path.	2025-04-14 06:10:43 +02:00
Lynne	77f777d925	ffv1/vulkan: redo context count tracking and quant_table_idx management ... This commit also makes it possible for the encoder to choose a different quantization table on a per-slice basis, as well as adding this capability to the decoder. Also, this commit fully fixes decoding of context=1 encoded files.	2025-04-14 06:10:42 +02:00
Lynne	6bad55eb17	ffv1: add a Vulkan-based decoder ... This patch adds a fully-featured level 3 and 4 decoder for FFv1, supporting Golomb and all Range coding variants, all pixel formats, and all features, except for the newly added floating-point formats. On a 6000 Ada, for 3840x2160 bgr0 content at 50Mbps (standard desktop recording), it is able to do 400fps. An Alder Lake with 24 threads can barely do 100fps.	2025-03-17 08:51:23 +01:00
