Accepted variables and functions in expressions for x and y parameters are :

dar input display aspect ratio, it is the same as (w / h) * sar
hsub, vsub horizontal and vertical chroma subsample values. For example for the pixel format "yuv422p" hsub is 2 and vsub is 1
line_h, lh height of each text line
main_h, h, H input height
main_w, w, W input width
max_glyph_a, ascent maximum distance from the baseline to the highest/upper grid coordinate used to place a glyph outline point, for all the rendered glyphs; a positive value, due to the grid
max_glyph_d, descent maximum distance from the baseline to the lowest grid coordinate used to place a glyph outline point, for all the rendered glyphs; a negative value, due to the grid
max_glyph_h maximum glyph height, that is the maximum height for all the glyphs contained in the rendered text, it is equivalent to ascent - descent.
max_glyph_w maximum glyph width, that is the maximum width for all the glyphs contained in the rendered text
n number of the input frame, starting from 0
rand(min, max) returns a random number included between min and max values
sar input sample aspect ratio
t timestamp expressed in seconds, NAN if the input timestamp is unknown
text_h or th height of the rendered text
text_w or tw width of the rendered text
x, y x and y coordinates, where the text is drawn, these parameters allow the x and y expressions to refer each other, so you can, for example, specify y=x/dar

The application can also scroll the text can by specifying the scroll direction from the list (10). You can also set the scroll speed (11).
