I found that the box_length is shorter than the text_length, and there is no option to adapt(Equal).
So I suggest ffmpeg.org can add a opption(like boxw_equal_textw) to adapt it ! the old source: box_w = FFMIN(width - 1 , max_text_line_w); box_h = FFMIN(height - 1, y + s->max_glyph_h); the new source: if(0==s->boxw_equal_textw){ box_w = FFMIN(width - 1 , max_text_line_w); }else{ box_w = (int)s->var_values[VAR_TEXT_W]; } _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
