thanks for the new info, my idea was to rescale the bounding box for the frame size change. Looks that we can just output a warning message and don't do the classification if the size changes, otherwise, the filter will give wrong result. > > Regards, > > -- > Nicolas George _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
