Detailed Description

Macro Definition Documentation

VLC_ANCILLARY_ID_DOVI

#define VLC_ANCILLARY_ID_DOVI   VLC_FOURCC('D','o','V','i')

VLC_ANCILLARY_ID_HDR10PLUS

#define VLC_ANCILLARY_ID_HDR10PLUS   VLC_FOURCC('H','D','R','+')

HDR10+ Dynamic metadata (based on ATSC A/341 Amendment 2094-40)

This is similar to SMPTE ST2094-40:2016, but omits the mastering display and target display actual peak luminance LUTs, the rectangular boundaries and ellipse coefficients, and support for multiple processing windows, as these are intentionally left unused in this version of the specification.

VLC_ANCILLARY_ID_ICC

#define VLC_ANCILLARY_ID_ICC   VLC_FOURCC('i','C','C','P')

Embedded ICC profiles.

VLC_ANCILLARY_ID_VPX_ALPHA

#define VLC_ANCILLARY_ID_VPX_ALPHA   VLC_FOURCC('v','p','x','A')

VPx alpha data.
