Is there any API on the iPhone 5S that allows an app to access the original 120 FPS version of videos captured from the Camera app's "Slo-Mo" mode?
I'm afraid I can't tell you exactly (got no iPhone 5S to test it) but according to this question you can capture at 60fps: Capture 60fps in iPhone app
Maybe its possible to just swap the 60 with a 120 and get a video at 120fps. Should be worth a try.
But if you're just interested in previously captured videos stored in Photos app then I'm quite sure there's no API for accessing 120fps videos directly

I'm (trying) to use HTTP-Live-Streaming in my app and after weeks of re-encoding it seems to work now without errors by the mediastream validator.
On my latest iPod Touch (iOS 4.0) with WiFi the videostream loads in 1sec and switches to the highest bandwidth stream.
On another test device iPhone 3G (iOS 3.0) with WiFi it takes up to 30 seconds to load the stream - although I see in my log files that it looks for the high quality stream after 1 second. But I get a black screen with audio only in the first 30 seconds. Is this problem to due the better CPU on the latest iPod touch or is it due to the iOS upgrade?
Also I'm fearing another rejection by Apple because the last time they checked my stream they only looked at each videostream for about 3 seconds and then rejected because they didn't see any video.
Take a closer look at the segmented files. Example: can you play the first low-quality MPEG-TS segment in VLC? Is their video there?
I've found iOS devices to be very picky about that they will and won't play. Make sure you are using a lowest common denominator code settings. I'm a big fan of The Complete Guide to iPod, Apple TV and iPhone Video Formats
Recently we've developed an iPhone app for an external company, and everything works fine in the app.
There is a section where the app pulls video from the client's server, and streams it into the iPhone's MPMoviePlayerController. This works fine on the iPhone and iPodTouch - both the video and the audio show up just great.
The problem, however, is that when the app is run on an iPad (using the iPad's iPhone simulator thingo that it does) only the audio plays, and no video can be seen.
Does anybody have any suggestions about what may be causing this? I thought perhaps it was the encoding, but then why would this prevent the video from playing on the iPad, and not the iPhone?
Use mpmovieplayerviewcontroller instead, you might find it works better.Here is a link to the ref http://developer.apple.com/iphone/library/iPad/index.html#documentation/mediaplayer/reference/mpmovieplayerviewcontroller_class/reference/reference.html
I want to write application on iPhone which will:
make some digital processing on video from iPhone camera (in real time)
send some graphics through TV-Out
Could You tell me if this above is possible on iPhone 3G or 3GS?
Can I have access to each pixel in video capturing via iPhone camera?
There are private access points to do both live video recording and TV out. They are not well documented so you won't find much about them though and you wouldn't be able to submit anything that uses them to the app store. Real time video capture will probably eventually become a public part of the SDK but TV is probably less likely at this point.
I want to play H.264 video streamed from network. To play video iphone provides the media player API. Does anyone one aware of any documented or undocumented API for decoding and playing single video frame?
Is it Live video or on demand ?
If live the only way is to use iPhone OS 3 with MediaPlayer.
take a look at the discussions group from apple there is some interesting thread.
is it possible to stream video to iphone/ipod touch over http without a proper streaming server with .net? may be some sort of progressive download?
The best way that I suggest is to use HTML 5. The iDevices (iPhone/iPod Touch/iPad) doesn't support Silverlight or Flash.
I think the mobile devices you are trying to watch the videos from have a 'video size limit' because when i test my website i test everything over wifi for real world scenarios and when i reach a certain video size i am not able to watch the video on that mobile device. videos under 1gb work great, but when i try watching a 2.5gb HD video it will not open the video on my ipod/ipad/iphone/android devices....
