Detailed Description

HDR output options.

When HdrInfo::enabled is true, the writer switches to a dedicated HEVC Main10 + BT.2020 output path that:

• Encodes with libx265 at 10-bit (AV_PIX_FMT_YUV420P10LE).
• Tags the stream with BT.2020 primaries, BT.2020 non-constant luminance matrix, and SMPTE ST.2084 (PQ) transfer.
• Converts incoming 8-bit sRGB RGBA shader output into PQ-encoded 10-bit YUV, placing SDR-range content at the 100-nit reference level inside the PQ signal (SDR-in-HDR-container).
• Copies mastering_display and content_light side data from the input stream when provided, so player HDR metadata is preserved.

This mode is intended for use when the input video is HDR; the 8-bit GL pipeline cannot reconstruct the original highlight precision, but the resulting file is a correctly-tagged HDR container.
