Hi,
The documentation of GstGhostPad contains the following note:
Note that GhostPads add overhead to the data processing of a pipeline.
I see that a GhostPad adds 4 additional function calls to the processing
pipeline to call the gst_pad_push() function on the internal pad after
gst_pad_push() has been called on the GhostPad. The functions add a few
checks, but basically just pass the pointer to the buffer to the internal pad.
While this is some overhead, I would think that this overhead is pretty low
compared to the remaining pipeline.
Therefore, I wonder why the documentation explicitly states that a GhostPad
adds overhead and if I am missing something important. Unfortunately, the git
history was not helpful to find the reason for the note.
Michael
