Detailed Description
A Virtual class for decoders.
Inspects Frame in_frame, does something, and writes to Frame out_frame out_frame class depends on the kind of Decoder, so that is defined in the subclasses

◆ output()
|
pure virtual |
< Return in_frame timestamp
Return a reference to the internal storage of the decoder where the decoded frame is. The exact frametype depends on the Decoder class (and decoder library)
Implemented in VideoDecoder, HwVideoDecoder, and DummyDecoder.
