I want to use some filter to produce one specified yuv/rgb image, and render text on that image via drawtext filter later in filter graph. Then run the filter graph, and get text_h and text_w from 'ff_vf_drawtext'. which filter is used to produce fake yuv/rgb image in ffmpeg?
Is there some efficient way to get the values of text_h and text_w?
