Changelog #

0.2.1 #

  • Shorten the package description to satisfy pub.flutter-io.cn metadata conventions.
  • Keep the iOS and macOS podspec versions aligned with the Dart package.

0.2.0 #

  • probeOgg: read channels, sample rate, and exact decoded length (VorbisInfo) without decoding any PCM — header parse + last-page scan only.
  • decodeOggInto: decode directly into a caller-provided native buffer, skipping the intermediate native allocation and the native → Dart copy. Buffer ownership stays with the caller; a too-small buffer throws VorbisDecodeException with VorbisDecodeException.outputTooSmall (nothing is ever written past the given capacity).
  • decodeOgg: the native PCM buffer is now allocated once at its exact final size (probed from the stream's last page) instead of growing via repeated realloc, removing transient memory peaks; a grow-as-you-go fallback remains for streams with a damaged or missing last page.
  • New native entry points vorbis_decoder_probe_memory / vorbis_decoder_decode_into; new error codes VORBIS_DECODER_ERROR_OUTPUT_TOO_SMALL (100) and VORBIS_DECODER_ERROR_STREAM_TOO_LARGE (101), plus integer-overflow guards on the PCM size computations.

0.1.0 #

  • Initial release.
  • decodeOgg / decodeOggAsync: decode a complete in-memory Ogg Vorbis stream to interleaved 16-bit PCM (VorbisDecoded), backed by the public-domain stb_vorbis decoder over dart:ffi.
  • Platforms: iOS (Swift Package Manager, CocoaPods fallback), Android (CMake/NDK), macOS (Swift Package Manager, CocoaPods fallback).
  • Host-machine test support via VORBIS_DECODER_FFI_LIBRARY / vorbisDecoderLibraryOverride and tool/build_host_lib.sh.
