Video: Audio plays fine. No picture though.

Question

I am having trouble getting a video to play on team members ipads.
It is encoded as an MP4 h.264 and I am streaming it from a common server. It plays fine on my ipad, but my two team members get only audio and no picture. Ideas?

Answer 1

I think it had to do with the other two ipads being newer with retina displays. I re-encoded after reading another thread about retina displays, and now all is fine.
Here the answer that was helpful to me in figuring out the problem:
"The reason that the videos were playing on older iPads but not on the current iPad Air has to do with how the videos were encoded. The ones that didn't play on the air had been encoded with the Field Order set to Lower First. When that was changed to 'progressive', the videos played fine on all.
All mobile devices have progressive scan screens, so progressive is usually the right choice to make. I don't know any specifics why earlier iPad models would play interlaced footage and the Air doesn't, but I can make a guess... Apple has been quietly deprecating a bunch of earlier codecs and QuickTime options. This is most noticeable in Mavericks on the desktop. Now, for example, QuickTime files using Apple Animation codec sit and convert to ProRes when opening, since the Animation codec isn't in QuickTime anymore." Adobe viewer, iPad retina, videos
