[Ipe-discuss] [ipe-discuss] Movie in an IPE presentation

I just had a look at pdfpc (https://pdfpc.github.io/) and Presentation (http://iihm.imag.fr/blanch/software/osx-presentation/), two apps for showing PDF presentations.

Both support videos, and both do NOT use the PDF movie annotations.  Instead, the user embeds in the PDF file only a link to a video, and then the player plays that video.   pdfpc will even embed the video inside the slide, Presentation will show it in a separate "movie view".

I have just tested that I can create files with (a slightly modified version of) Ipe that will contain videos that display correctly with pdfpc and Presentation.   In pdfpc the video is indeed nicely embedded inside the slide, and you can set it up so that it starts automatically when you enter the slide.   In Presentation you have to click on the movie object on the slide, then the movie starts playing in a separate movie view.

I will make it possible to use this in the next version of Ipe (you cannot currently do this with the released Ipe version, as it needs a different type of link annotation - a /Launch action rather than a /URI action).

Now that we have IpePresenter and are no longer restricted by the possibilities of PDF for Ipe presentations, I'm planning to add animations to Ipe in the near future.
