• Add VPP filter preview. ( With HWEncVppPreview )
• Add --seek support for avi/avs/vpy input.
• Speed up y4m/raw output writes.
• Accept auto for --vpp-onnx-cache-dir, matching the documented default cache location.
• Fix --vpp-colorspace failing with no path when range and matrix (or similar) change in the same stage.
• --vpp-colorspace inherits unspecified parameters from the input or the previous stage, and the output VUI follows the conversion. HDR2SDR and LUT keep their default output.
• Fix a crash when multiple --vpp-colorspace conversions are chained.
• Improve timestamp output of --vpp-afs and --vpp-kfm mode=24.
• Fix --vpp-afs timestamps drifting with --avsync vfr or a custom --timebase.
• Fix an abort during flush that kept queuing empty work, so the process never exited and memory use kept growing.
• Fix GPU performance counter thread force-termination running after detach, seen with --perf-monitor.
