Question about subtitles

[sbenmeddour]

Hello

How is subtitle font size scaled?

Example: subtitle.font.size = 20, It does not look like it is real pixels

Do you use a fixed viewport, video size, or surface size to scale subtitle.font.size

too large or too small? no scale in my code. but i see mpv scales the value by track->PlayResY/720, default is 288/720

Scaling subtitles with MDK is smaller than MPV, probably because you don't use the same frame size for subtitles i guess

I got it working with mpv, i can scale with device's screen density, because i already know subtitles frame height is 720

--sub-font-size=<size>
Specify the sub font size. The unit is the size in scaled pixels at a window height of 720. The actual pixel size is scaled with the window height: if the window height is larger or smaller than 720, the actual size of the text increases or decreases as well.
Default: 38

To get correct scaling i might need to know what did you set for ass PlayResY (surface size, video size or hardcoded size ?)
