Prefer the single-pass Vulkan libplacebo filter over the CPU zscale chain for HDR->SDR tonemapping when the agent ffmpeg has it. One GPU pass does tonemap + BT.709 primaries/transfer/matrix + 8-bit yuv420p, replacing the four-stage zscale chain and its trailing format=/setparams. Higher quality, far cheaper than the CPU path, and present on builds that lack zscale. - FFmpegSupportsLibplacebo probe (cached, mirrors FFmpegSupportsZscale) - HasLibplacebo on TranscodeRuntime, wired from buildTranscodeRuntime - hls.go: videoTail picks libplacebo when present (not h264_vaapi), else keeps the zscale tonemap + format chain - test: libplacebo replaces the zscale chain, never runs alongside it |
