hi,
what is the video format for epub book that works on calibre ?
I tried .mp4 and .ogg but they didn't work on calibre!! :blink:

mpegs in .m4v seem to work in calibre

thanks mzmm,

I tried .m4v but still caliber can't play the video !! :blink:

Calibre is not designed for ePub 3. So any sort of multimedia that does work is probably a fluke.
