Constant libjxl_sys::JXL_DEC_NEED_DC_OUT_BUFFER

pub const JXL_DEC_NEED_DC_OUT_BUFFER: JxlDecoderStatus = 4;

The decoder is able to decode a DC image and requests setting a DC output buffer using JxlDecoderSetDCOutBuffer. This occurs if JXL_DEC_DC_IMAGE is requested and it is possible to decode a DC image from the codestream and the DC out buffer was not yet set. This event re-occurs for new frames if there are multiple animation frames.
