- Replace direct FFmpeg usage in the test suite (channel layout masks, pixel/sample format constants, AVFrame field access, sws_scale) with the bridge equivalents and the olive::AVFrame adapter - Drop CoreRational.ToAVRational (API removed with core's FFmpeg dependency) and the GetSwsColorspaceFromAVColorSpace tests (helper moved inside the bridge) - New ffmpeg_bridge_test.cpp exercises the C API directly: constants vs core, error strings, pixel format utilities, frames/packets, scaler, resampler, audio graph tempo processing, probe/decoder round-trip on tests/demo.mp4 (including hw-frame transfer), SRT subtitle reading, and encoder end-to-end tests (PNG video and PCM audio probed back)
