First of all, thank you for making this awesome tool! I am using it regularly for my presentations at uni and am unbelievably happy with it. There is just one tiny thing I am struggling with: embedding media. At the moment, it seems like you can't embed audio or video files with xelatex in such a way that it is played by
If I can be of any help, feel free to let me know! |
