GstBatchBufferWrapper Class Reference

Detailed Description

TODO re-design GstBatchBufferWrapper to be video specific and NvDsBatchBufferWrapper generic ; Also rename the new data-structures according to the media they contain.

The GStreamer wrapper code for NvDsBatchBufferWrapper which represent one batched buffer. NOTE: None of the APIs in this class are thread-safe
