v3.120.3 This minor release fixes a number of regressions surrounding memory imports and DRM modifiers, specifically aimed at issues that arose with mpv's --hwdec=vaapi. Changes: - `pl_fmt.modifiers` now always includes DRM_FORMAT_MOD_INVALID on OpenGL, which instructs the implementation to not specify modifiers - passing a DRM modifier not in the list of supported modifiers is now considered a hard error, to rule out non-working hwaccel formats Fixes: - fix a crash when using sampling shaders on textures with unknown formats - fix improperly specified SDL header imports in the demos - fix an issue where the vulkan texture handle capabilities were testing for presence of the wrong extension - fix an issue where non-enabled DRM modifier structs were accidentally linked into the pNext chain, causing issues with some drivers
