get_frames_impl()

void MayaFlux::Kakshya::VideoStreamContainer::get_frames_impl ( void *  output, size_t  count, uint64_t  start_frame, uint64_t  num_frames, const std::type_info &  type  ) const

overrideprotectedvirtual

Implementation-specific method to retrieve multiple frames.

Implementations write up to count * frame_size elements into output, starting from start_frame. The type parameter indicates the expected element type; implementations may choose to support or reject it based on their native data type, but must not write past the output buffer regardless.

Parameters

output	Pointer to caller-owned buffer for frame data
count	Number of frames to retrieve (output buffer size in frames)
start_frame	First frame index to retrieve
num_frames	Number of frames to retrieve
type	Type information for the expected element type (e.g. float, uint8_t)

Implements MayaFlux::Kakshya::NDDataContainer.
