This framework supports the playback of movie files with the . 5 Mbps, 640 by 480 pixels, 30 frames per second, Low-Complexity version of the H. 264 video, up to 768 Kbps, 320 by 240 pixels, 30 frames per second, Baseline Profile up to Level 1. For information about the classes of the Media Player framework, see Media Player Framework Reference.
Other types of Flash video are not supported. Lossless Quicktime with the Animation codec and lossless APNG can both be used in an iOS app with my AVAnimator library. I don’t get why they say 640 by 480 pixels. Can I not play 1920×1080 videos?
This answer is dated from 2009 and of course at that time the devices weren’t able to playback hd video. Baseline Profile up to Level 3. There seems to be some issue with playing . 3GS and 4 devices but fail with 3G and below even though they fit within the Apple specs.
264 video, High profile and AAC audio, in container formats . MPEG Segment files are used for HTTP Live Streaming. For extended length videos longer than 10 minutes you must use HTTP Live Streaming, which is H. AAC in a series of small . App Store Review Guidelines rule 2. 264 is the only game in town. There are several different feature tiers or “profiles” available in H.

Apple-provided library that gives access to a HEVC codec to developers. 1080p HD video recording at 30 fps or 60 fps. Obviously the phone can play back what it can record, so we can guess that 3840×2160 at 30 fps and 1920×1080 at 60 fps represent design limits of the phone. In addition, the screen size on the 6S Plus and 7 Plus is 1920×1080. So if you’re interested in playback on the phone, it doesn’t make sense to send over more pixels then the screen can draw.
However, streaming video is a different matter. Since networks are slow and video is huge, it’s typical to use lower resolutions, bitrates, and frame rates than the device’s theoretical maximum. The most detailed document giving recommendations for streaming is TN2224 Best Practices for Creating and Deploying HTTP Live Streaming Media for Apple Devices. This table is from May 2016. As you can see, Apple recommends the relatively low resolution of 768×432 as the highest recommended resolution for streaming over a cellular network.
