0.2.11

0.2.9

0.2.8

• add RecorderLogSource.minigpu: routes native minigpu/Dawn log lines through the unified Recorder log callback; Recorder.minigpuLevelFor public helper for tests; 12 new tests in log_level_test.dart

0.2.7

• fix FormatException on non-UTF-8 bytes in MiniAV log callback: use Utf8Decoder(allowMalformed: true) instead of toDartString()
• Increment minigpu to 1.4.4

0.2.6

• fix: add missing dart:convert import for Utf8Decoder (compilation error introduced in 0.2.5).

0.2.5

• fix: FfmpegShim.setFfmpegLogCallback now uses Utf8Decoder(allowMalformed: true) when decoding native C strings, so FFmpeg log messages containing non-UTF-8 bytes (Latin-1 filenames, Windows-1252 error strings, etc.) no longer throw FormatException: Unexpected extension byte.

0.2.4

• fix: FfmpegShim.tryLoad() no longer poisons its cache when called before FFmpeg has been loaded. The shim DLL imports avcodec/avutil; if those aren't loaded yet on Windows, the shim load fails and previously the failure was cached forever — breaking the audio encoder when Recorder.setLogLevel/setLogCallback was called early. tryLoad now skips silently (without caching) until FFmpeg is loaded.

0.2.3

• FFmpeg log forwarding shim bridge (miniav_shim_set_ffmpeg_log_callback, miniav_shim_set_ffmpeg_log_level); FfmpegShim.setFfmpegLogLevel, setFfmpegLogCallback; ABI bumped to 8; export FfmpegShim from barrel
• add unified Recorder.setLogLevel and Recorder.setLogCallback routing all native logs (MiniAV + FFmpeg) through a single Dart callback

0.1.1

• updated to latest miniav/minigpu deps

0.1.0

• Initial release. FFmpeg-backed encoder, decoder, muxer and demuxer registered against miniav_tools_platform_interface.
• Software encode for H.264 / HEVC / VP9 / VP8 / AV1 / MJPEG / ProRes via libavcodec.
• Stage A hardware encode (CPU frame in, encoded packet out) using NVENC / AMF / QSV / VideoToolbox / MediaFoundation / V4L2 M2M.
• Stage B zero-copy D3D11 encode on Windows: takes an ID3D11Texture2D NT shared handle directly without any PCIe transfer or colour conversion.
  • FfmpegD3d11HwEncoder.openWith(cfg, vendor, existingD3d11Device, sourceTextureFormat) lets callers inject their own ID3D11Device* so the encoder runs on the same DXGI adapter as an external GPU API (Dawn / WebGPU). Required for cross-API NT-handle sharing — different adapters fail with E_INVALIDARG.
  • sourceTextureFormat selects bgra (default; matches DXGI screen capture and minigpu SharedOutputTexture) or rgba. The hwframes pool is allocated with this sw_format so CopySubresourceRegion from the caller's texture stays in the same DXGI type group.
• MP4 / Matroska / MPEG-TS muxer with byte-buffer, file and streaming callback outputs. Container-level fragmenting for low-latency streaming.
• Auto-download of FFmpeg shared libraries (BtbN GPL builds) on first run; set MINIAV_TOOLS_FFMPEG_NO_AUTODOWNLOAD=1 to opt out.
