0.1.2 - 2026-09-24

Added

  • Controls to disable existing Vulkan GPU timestamp instrumentation or sample complete staged acquire-to-release intervals without changing synchronization. Existing consumers keep staged-frame timing enabled by default.
  • Vulkan timing status notifications and ImportedImageSync::has_gpu_timing_resources for diagnostics.
  • Driver-free regression tests for timing policies, release-fence gating, sync-owner reuse, and backward compatibility with existing Vulkan consumers.

Fixed

  • Fixed macOS compilation of video frame helpers while preserving 64-bit DMA-BUF allocation sizes and inode identities on Linux, including ARMv7.
  • Made descriptor, EGL, and dispatcher lifecycle tests portable to macOS.
  • Prevented out-of-memory errors during Vulkan timestamp query-pool allocation from failing synchronization setup. Query readback now omits timing samples instead of failing release-completion polling on NOT_READY or out-of-memory errors.
  • Disabled Vulkan timestamp instrumentation for non-finite or non-positive timestamp periods and timestamp valid-bit counts greater than 64.
  • Correctly mark the Vulkan context as device-lost and return a device-loss error when timestamp query-pool allocation or readback reports ERROR_DEVICE_LOST.

0.1.1 - 2026-09-05

Fixed

  • Fixed ARMv7 compilation of DMA-BUF probing by using 64-bit stat and seek APIs for allocation sizes, file positions, and inode identities.
  • Added ARMv7 compile and Clippy checks to the release gate.

0.1.0 - 2026-09-03

First public release.

Added

  • Framework-neutral Elixir and Rust frame formats for owned binary video and Linux DMA-BUF video.
  • Support for RGBA8888, RGB888, Gray8, Gray2, BW1, and DMA-BUF pixel formats.
  • Explicit visible geometry, colorimetry, alpha, DRM modifier, and acquire-fence metadata.
  • Validation for frame, format, binary-plane, and DMA-BUF descriptors.
  • Bounded leases and consumer helpers for safe ownership transfer and release.
  • Optional Rustler, EGL, and Vulkan integration APIs.

Limitations

  • DMA-BUF file descriptors are process-local and cannot be sent directly to another Erlang node.
  • Metal and Direct3D adapters are not included.
