 If both @var{text} and @var{textfile} are specified, an error is thrown.
 
+@item text_source
+Text source should be set as side_data_detection_bboxes if you want to use text data in
+detection bboxes of side data.
+
+If text source is set, @var{text} and @var{textfile} will be ignored and still use
+text data in detection bboxes of side data. So please do not use this parameter
+if you are not sure about the text source.
+
 @item reload
 If set to 1, the @var{textfile} will be reloaded before each frame.
 Be sure to update it atomically, or it may be read partially, or even fail.
