Detailed Description

Holds picture information for the current frame decode operation.

Note: This picture information is passed with NvMediaParserClientCb::DecodePicture callback. Client will call NvMediaVideoDecoderRenderEx with this information to NvMedia video decode component to get the current frame decoding done.; This picture information is passed with NvMediaParserClientCb::DecodePicture callback. Client will call NvMediaIDERender with this information to NvMedia decode component to get the current frame decoding done.
