Hi FFmpeg developers, The delogo video filter currently doesn't check the logo area passed as parameters for validity. If the logo area is partly outside of the frame or inside but too close to the border, the code will silently trim the area to make it fit inside the frame, then go on, with undesirable results.
I would like to add a check for the delogo filter parameters to ensure that there is enough frame room around the area to execute the algorithm. My question is: do I have to do this check in filter_frame() for every frame, or can I do it once in init() and be done with it? Or is it supposed to be done in config_props()? I read the documentation about config_props but I'm afraid it did not really enlightened me as to what this callback is for. For performance reasons I'd like to avoid performing the same check repeatedly. Sorry if this sounds like a newbie question but well I guess that's what I am. I'm still not sure what is the difference between filter links and pads (or more generally what pads are)...
