extract_frame() [1/2]

template<ProcessableData T>

std::span< T > MayaFlux::Kakshya::extract_frame ( const std::vector< std::span< T > > &  channel_spans, uint64_t  frame_index, std::vector< T > &  output_buffer  )

noexcept

Extract a single frame from planar data (returns interleaved).

Template Parameters

T	Data type.

Parameters

channel_spans	Vector of spans, one per channel.
frame_index	Index of the frame to extract.
output_buffer	Buffer to store interleaved frame data.

Returns

Span containing the interleaved frame data.
