ffmpegplugin

Compressed and streaming audio — MP3, AAC, M4A/MP4, Ogg/Vorbis, Opus, FLAC, WAV, AIFF, AC3, MP2, WMA and IFF-8SVX — decoded in-process by FFmpeg's LGPL libav* libraries. No command-line ffmpeg is spawned or bundled.

Extensions: .m4a .aac .mp3 .mp4 .ogg .opus .flac .wav .aiff .aif .mp2 .mpeg .ac3 .wma

Local files, progressive downloads and HTTP(S) radio streams all route here. A decode-only, LGPL build of FFmpeg 8.1.1 is vendored at external/ffmpeg-lgpl/.

Streaming notes

  • Progressive streaming runs curl → fifo → libav. SIGPIPE on the fifo is suppressed with F_SETNOSIGPIPE.
  • .aif / .mp4 / .m4a cannot be demuxed from pipe:0 (they need seeks), so those route via streamUrl instead of the fifo path.
  • YouTube streams need libav's reconnect flags; a TLS -9806 failure means googlevideo dropped the socket.
  • The packaged dylibs live in Contents/Frameworks and bake @executable_path rpaths.
