Hi, http://ffmpeg.org/doxygen/2.8/vf__drawtext_8c.html#a65f3f8df0fa6740ed48a631c89cde373
static int filter_frame(AVFilterLink *inlink, AVFrame *frame) In the end of the above function, text_w and text_h are shown, which are stored in DrawTextContext:var_values[VAR_TEXT_W] and DrawTextContext:var_values[VAR_TEXT_H]. How to get the two value via ffmpeg lib, i.e. DrawTextContext:var_values[VAR_TEXT_W] and DrawTextContext:var_values[VAR_TEXT_H]? B.R. Andrew
