@XCanG Not sure I understand what you mean.

I know what calc is. I'm asking how you propose to use it to solve this problem.

Sure, but that requires knowing that the first is 30px high. If libjass knew that then it wouldn't need to use calc at all since it could just absolutely position...

Again, my point is that libjass doesn't know the height of the subs to be able to position things with calc. If it did know the height of the subs,...

If there is a PR with the option I will consider it. Alternatively you can look at https://github.com/Dador/JavascriptSubtitlesOctopus instead. With the direction browsers are moving in with respect to SVG...

Yeah, exactly. The requester in your case is the Emby library. --- Also, the assert was introduced in [this commit](https://github.com/Arnavion/libjass/commit/1cefb68b47a56f12ccf0d01961127a4e1f7ecc75) that actually tried to catch scripts with no `Script Info`...
