StillKit 2.0 - FFmpeg 9.0 "Lei"
================================

Launch StillKit_v2.0_FFMPEG9.exe with ffmpeg9.exe and ffprobe9.exe kept in
the same folder. StillKit 2.0 rejects FFmpeg versions older than 9.0.

Included FFmpeg build: 9.0 essentials_build by gyan.dev, published from the
FFmpeg 9.0 stable branch. The downloaded archive was validated against the
publisher SHA-256:
e6b54767a6065919048f1a098eb27211ca4e12b4348a05d88777a5855d0b6e71

Rendering improvements:
- automatic NVIDIA, Intel, AMD and Direct3D hardware decode negotiation;
- automatic CPU decode retry;
- NVENC / Quick Sync / AMF H.265 review encoding with libx265 fallback;
- one metadata probe per source instead of two;
- video-only stream mapping during extraction;
- reduced process/UI progress overhead;
- FFmpeg 9-compatible variable-frame-rate syntax.
- animated WebP input support through FFmpeg 9's new decoder and demuxer.

FFmpeg 9 features considered but intentionally not enabled by default:
- frc_amf would synthesize frames and is inappropriate for still extraction;
- transpose_cuda adds transfers for CPU image output and is not faster here;
- ONNX GPU support would require a much larger non-essentials dependency set;
- AMF memory mapping becomes useful only in a future zero-copy GPU pipeline;
- HDR metadata support belongs in an explicit color-managed export mode.
