1 – Release Notes
GeeXLab 0.29.1.0 for Windows 64-bit is available with the following changes:
– an improved FFmpeg plugin with better video / audio synchronization. The frame seeking feature has been added so we can now step forwards and backwards. FFmpeg is a powerful piece of code but its use can be very hard especially with audio/video sync and frame seeking. The audio playback is done by SDL2. This brand new FFmpeg plugin will the be core of an upcoming tiny video player made with GeeXLab.
– the Vulkan plugin has been updated with support of mipmapping (GeeXLab 0.29.0), frame buffer reading for screenshots and few bugs have been fixed (buffer overflow, swapchain resize). The Vulkan plugin has been tested with validation layers of latest Vulkan SDK 1.1.121.
– new demos / code-samples are shipped with GeeXLab. These demos are available in:
{GeeXLab folder}/demopack-gl21/, {GeeXLab folder}/demopack-gl32/ and {GeeXLab folder}/demopack-gl32-shadertoy/.
GeeXLab 0.29.1.0 for Windows has been compiled on Windows 10 64-bit v1903 + VS2017 v15.9.16.
