iPhone video encoding specs for streaming?
Today is the day when people line up to get the next generation in mobile phones. iPhone hysteria is on the loose and you cant escape hearing about iPhones in the news and on the net. I wont be getting an iPhone any time soon esp since It would require me to break my Sprint contract and go with Cingular/AT&T and loose my beloved EDVO data speeds to EDGE.
With all of that said anyone who has an iPhone would you please visit the best video sites and test out a few videos at http://mvstreamer.mobi .
I’m also looking for any videos encoded for the iPhone so I can add in streaming support for iPhone users. I don’t expect this to look nice since the video specs are 320×240 or 640×480 at EDGE data rates which isn’t great and not to mention the latency issue. I will be adding bigger video sizes soon but don’t expect any miracles for those screen sizes, getting a good looking qcif video at the current data rates on EDGE is tough enough with out turning it into a blocky slide show.
iPhone Specs from Apple:
Video formats supported: H.264 video, up to 1.5 Mbps, 640 by 480 pixels, 30 frames per second, Low-Complexity version of the H.264 Baseline Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats; H.264 video, up to 768 Kbps, 320 by 240 pixels, 30 frames per second, Baseline Profile up to Level 1.3 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
UPDATE: My buddy is in line for his iPhone so Ill be able to do some tests soon, but I would still like to hear from other iPhone users.
