Replace every direct FFmpeg call in the editor and the render worker with the pure C ffmpeg_bridge API, wrapped in thin C++ adapters that preserve the original interfaces: - avframeptr.h: olive::AVFrame adapter around FBFrame handles - ffmpegutils: format conversion helpers on FB_* constants; the int overload is renamed GetCompatibleBridgePixelFormat to avoid a silent overload-resolution trap with the PixelFormat enum - ffmpegdecoder/ffmpegencoder: rewritten as handle-based adapters over FBDecoder/FBProbe/FBEncoder/FBScaler/FBResampler - audioprocessor: FBAudioGraph push/pull adapter - pluginrenderer/OliveClip: sws/pixdesc usage converted to FBScaler and fb_pix_fmt_* queries - AudioParams/channel layouts are plain uint64_t masks everywhere Build integration: the root project no longer links FFMPEG directly; only ffmpeg_bridge does. Binaries resolve the bridge library at runtime via @loader_path inside the macOS app bundle (copied there post-build) and via $ORIGIN/../ffmpeg_bridge/bin on Linux; on Windows the DLL is installed next to the executables, so packages on all three platforms ship the bridge library. ffmpeg_bridge gains the extra API the adapters need: fb_frame_make_writable, fb_decoder_get_format_duration, fb_resampler_convert_frame, FB_PIX_FMT_YUV440P, SRT validation in fb_probe_read_subtitle_stream, packed/planar fixes in fb_encoder_write_audio, and a component-size fix in fb_pix_fmt_component_size.
