Detailed Description

@dev-note: Tiler Composition Steps: 1) Extract GstNvStreamMeta from the input muxed buffer 2) loop for GstNvStreamMeta->num_filled (number of filled batch buffers) a) Each buffer according to its stream_id is assigned a blit position - (x,y) [width, height] 3) NvBufSurfaceComposite() each stream buffer on the output buffer at the computed tile position 4) Iterate through NvDsBatchMeta->NvDsFrameMeta[according_to_stream_id] ->NvDsObjectMeta list and scale all bounding boxes to the computed tile rect
