[Convert] Tested and fixed with videotestsrc
This is not an issue. Don't be alarmed.
- Regardless of videotestsrc framerate, convert2tensor gives ~1000 FPS outputs.
. This happens when a sink-element attached at the src-pad of this element is not synching. Add sync option to the sink element.
How-to-test:
$ gst-launch-1.0 --gst-plugin-path=/PATH_TO_BUILT_SO videotestsrc ! video/x-raw,width=280,height=40,framerate=1/1 ! convert2tensor ! filesink location="test.log" sync=true

[Convert] Apply x-raw/RGB format data structure.
Data of x-raw/RGB is:
[height][width][RGB] and width has padding with stride = 4.
Thus, tensor output of convert2tensor generates width = 4 x N with zero-padding.

[Converter] Get tensor metadata from sinkpad when it is created.
Sinkpad is created when a source element is attached to this filter (convert2filter).
Convert2filter becomes aware of its metadata (dimensions of tensor) at this point.
Thus, configure the metadata with the event handler.

An empty template for GST Plugin, "Convert2Tensor".
1. This is to draft & verify "other/tensor" GST type design.
2. Then, this will work as converter from media sources for NN filters.
