The short answer is the iPhone supports H 264 video  High profile and AAC audio  in container formats  mov   mp4  or MPEG Segment  ts  MPEG Segment files are used for HTTP Live Streaming   For maximum compatibility with Android and desktop browsers  use H 264   AAC in an  mp4 container  For extended length videos longer than 10 minutes you must use HTTP Live Streaming  which is H 264   AAC in a series of small  ts container files  see App Store Review Guidelines rule 2 5 7    Video On the iPhone  H 264 is the only game in town   1  There are several different feature tiers or  quot profiles quot  available in H 264  All modern iPhones  3GS and above  support the High profile  These profiles are basically three different levels of algorithm  quot tricks quot  used to compress the video  More tricks give better compression  but require more CPU or dedicated hardware to decode  This is a table that lists the differences between the different profiles   1  Interestingly  Apple s own Facetime uses the newer H 265  HEVC  video codec  However right now  August 2017  there is no Apple-provided library that gives access to a HEVC codec to developers  This is expected to change at some point  In talking about what video format the iPhone supports  a distinction should be made between what the hardware can support  and what the  much lower  limits are for playback when streaming over a network  The only data given about hardware video support by Apple about the current generation of iPhones  SE  6S  6S Plus  7  7 Plus  is that they support  4K  3840x2160  video recording at 30 fps 1080p  1920x1080  HD video recording at 30 fps or 60 fps   Obviously the phone can play back what it can record  so we can guess that 3840x2160 at 30 fps and 1920x1080 at 60 fps represent design limits of the phone  In addition  the screen size on the 6S Plus and 7 Plus is 1920x1080  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  Figure 3 in that document gives a table of recommended streaming parameters   This table is from May 2016  As you can see  Apple recommends the relatively low resolution of 768x432 as the highest recommended resolution for streaming over a cellular network  Of course this is just a recommendation and YMMV  Audio The question is about video  but that video generally has one or more audio tracks with it  The iPhone supports a few audio formats  but the most modern and by far most widely used is AAC  The iPhone 7   7 Plus  6S Plus   6S  SE all support AAC bitrates of 8 to 320 Kbps  Container The audio and video tracks go inside a container  The purpose of the container is to combine  interleave  the different tracks together  to store metadata  and to support seeking  The iPhone supports  QuickTime  mov  MP4  and MPEG-TS   The  mov and  mp4 file formats are closely related   mp4 is in fact based on  mov   however  mp4 is an ISO standard that has much wider support  As noted above  you have to use MPEG-TS for videos longer than 10 minutes
