Why can't you embed a YouTube video in InDesign ???????????????
Using 6CC. Makes this program pretty well useless for any web application.
Leave a place holder for it in InDesign, then export the PDF. Add the video with Acrobat Professional.
I am looking at creating an interactive EPUB book.
I've branched this off and moved to the EPUB forum. Please do not re-open year old threads that have nothing to do with your question.
I believe the EPUB3 spec requires MP4, H264 encoded video. There are conversion applications I've seen for converting YouTube video to MP4 (I've never used them).
