How can iPhone play Youtube Videos?
But now that we've seen iPhone playing Youtube videos, its a general question, how can this be possible? Has Apple allowed Flash only for the Youtube videos?
The answer is NO. iPhone supports H.264 video compression standard. H.264 is an equivalent to MPEG-4 part 10 or MPEG-4 AVC (Advanced Video Coding). YouTube has encoded the plethora of videos available in the site and iPhone can play that format. The audio encoding is in AAC.
