Hello,

I am trying to test our Wowza VOD player on iOS. Although the newest iPhone seems to be able to play any dimension of video, I have had less success with a couple of iPads that are just a couple of years old. It seems they will only play videos of 640x480 or smaller (ratio didn’t matter). The only difference I made in the encoding process was the dimensions.

Is this an expected behavior that I should account for by providing an alternate version of the video? Or is it possible I am getting something else wrong in the encoding process? I can provide more information, but I’m not sure what’s relevant. I appreciate any help.
