[FFmpeg-devel] Filters

[JULIAN GARDNER]

How do I fix a filter so that it takes in 1 input but has no output, this is part of a project and this part is a detection filter, it does nothing else.

The problem at the moment is that with the current filter, based on drawbox, is that it produces an output which i need to the use overlay to dump.

Is there a video filter which has 1 input but 0 outputs
