Hi. Having a created a demo video for my application, I have a video in "portrait" orientation, i.e., the movie is 320 x 480 (w x h). You can see the movie(s) here (for mobile Safari): http://www.christian-fries.de/iphone/serialmail/demos and here (for standard browsers): http://www.christian-fries.de/iphone/serialmail and here (You Tube) http://www.youtube.com/watch?v=R7dWKhcrRV8 I realized several odd things which I could not resolve: 1) If I add the video to iTunes and sync it with iPhone, then iPhone plays in landscape orientation, adding huge black bars to the left and the right. Can this be changed? 2) If I post the video to YouTube it is also converted to landscape. I assume this cannot be changed since all YouTube videos have the same aspect ratio. However, the video quality is also degraded (compare the two above). Is it possible to have the video in better resolution? Should I upscale the video to HD by hand? If so: How can this be done? 3) If I create a webpage with dashcode (using the "video" element) the video starts in landscape mode, but if you rotate the iPod/iPhone back and forth then it rotates to portrait (contrary to whats happens in 1)). How can I achieve that the video starts right off in portrait orientation? See http://www.christian-fries.de/iphone/serialmail/demos for an example. Note however that on http://www.christian-fries.de/iphone/serialmail which uses the embed tag the video plays right off in portrait mode. 4) If I create a Cocoa app to play a movie using "MPMoviePlayerController" the movie plays always in landscape adding black bars to left and right - as in 1). Can I programmatically play the movie in portrait? Best Christian PS: Sorry for packing four questions into one post.
