Now when clicking on the trailer at the top on the iPhone it launches the video player that the iPhone uses and the video start streaming in (if your on wifi).

Of course this is pretty neat especially if your connected to a wifi hotspot but doing any sort of streaming over EDGE (at least from our tests) things are slow, buffering, hangs in the trailer etc. If you want to stream over EDGE your going to greatly reduce your quality event to the point where your seeing just a macro block slide show with lots of latency/buffering.

I put together a iPhone demo page to test out a video I encoded here. I recommend loading this on wifi connection, but would be curious to see how it runs on EDGE for some people.

I have encoded and tested the following:

mpeg4 + aac (hinted non hinted)

  • doesn’t work via DSS or direct html link Safari doesn’t understand RTSP and http:// linked videos it wants to load into memory.

h264 + aac (hinted non hinted)

  • doesn’t work via DSS or direct html link Safari doesn’t understand RTSP and http:// linked videos it wants to load into memory.

Asking my buddy to visit m.youtube.com via safari and test a video from the page also doesn’t work for him either.

Error: safari can’t open the page because the address is invalid

So, unless you can develop your own custom application like the youtube one right now looks like we are out of luck.

User Agent String for iPhone is:

Mozilla/5.0 (iPhone; U; CPU like Mac OS X; en) AppleWebKit/420+ (KHTML, like Gecko) Version/3.0 Mobile/1A543a Safari/419.3

If anyone comes up with a solution I would love to hear it.
