_NvDsBatchMetaΒΆ
-
struct
_NvDsBatchMeta Holds information about a formed batch containing frames from different sources.
NOTE: Both Video and Audio metadata uses the same NvDsBatchMeta type. NOTE: Audio batch metadata is formed within nvinferaudio plugin and will not be corresponding to any one buffer output from nvinferaudio. The NvDsBatchMeta for audio is attached to the last input buffer when the audio batch buffering reach configurable threshold (audio frame length) and this is when inference output is available.
