I think you will need to give more information about what you are trying to
accomplish. I do not understand why you would make a filter to double the
dimensions of the image.
In MLT, the consumer expects to receive the image size that it has requested.
The producer has normalize filters (like resize) to ensure that happens. If you
want your consumer to receive a different size image, then you should configure
your consumer to request that size.

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_______________________________________________
