One important thing to note is that "iDevices" doesn't support all the varieties of mp4. Here is a small list about MPEG-4 and H.264 supported varieties.
According to Apple official website, iPad or iPhone 4S is only compatible with H.264 or MPEG-4 video format with the following specifications:
If it is H.264 video, it should meet: up to 1080p, 30 frames per second, High Profile level 4.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats;
If it is MPEG-4 video, it should meet: up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps per channel, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats;
But there are some forums saying that in fact, the iPad specifications are these:
iPad Supported Video Format
H.264 video (up to 720p, 30 frames per second; main profile level 3.1 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats)
MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats.
