The library lives outside of app/ and is the only component that includes FFmpeg headers or links FFmpeg libraries. All objects (frames, packets, decoder/encoder instances, scalers, resamplers, audio filter graphs) are identified by opaque handles and never leave the library. Public surface (include/ffmpeg_bridge/ffmpeg_bridge.h): - FBFrame/FBPacket: AVFrame/AVPacket wrappers with field accessors - FBDecoder: demux+decode instance with hwaccel fallback logic - FBProbe: file probing, per-stream details, subtitle reading - FBScaler/FBResampler/FBAudioGraph: swscale/swresample/avfilter wrappers - FBEncoder: full export encoder (video filter graph, audio resampling, subtitles) ported from FFmpegEncoder - FB_* constants mirror AV_* values, verified by static_asserts against the real FFmpeg headers inside the library Two small bugs in the ported encoder were fixed: the resampler is now properly freed with swr_free() (was re-initialized with swr_init() and leaked), and codec option dictionaries are freed after avcodec_open2().
