Hey, MLT guys I have added a video SR filter (super-resolution) to MLT, and use it in Shotcut. However, the filter does not work very well. The problem is that the profile width/height from source video (e.g. iw, ih) is different from the frame size after the SR filter processing (e.g. 2*iw, 2*ih), and also the exported video can have another size. As a result, the exported video can be part of the frame generated by my SR filter, if the exported video size is set to be smaller than 2*iw, 2*ih.
I code the SR filter, referring to the mlt\src\modules\core\filter_resize.c. Should I move to another reference or should I set some frame property to let the MLT know that the frame size has been changed by my filter? Thank you very much! Best regards
