Subject: [FFmpeg-devel] [PATCH 13/13] ffv1: add a Vulkan-based decoder
Date: Mon, 10 Mar 2025 04:08:59 +0100
Message-ID: <20250310030912.60902-3-dev@lynne.ee> (raw)
In-Reply-To: <20250310030912.60902-1-dev@lynne.ee>
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.
