iphone - How to effectively transfer real time video between two iOS device (Like facetime, skype, fring, tango) -

-

i know how frame ios sdk. [how capture video frames camera images using av foundation(http://developer.apple.com/library/ios/#qa/qa1702/_index.html)] it's pixel, , can transfer jpeg.

what way want transfer video this:

one ios device a:

  1. get pixel or jpeg call function

-(void)captureoutput:(avcaptureoutput *)captureoutput didoutputsamplebuffer:(cmsamplebufferref)samplebuffer fromconnection:(avcaptureconnection *)connection

  1. using existed technology encoding h.264 - ffmpeg

  2. encapsulate video ts stream

  3. run http server, , wait request

the other ios device b:

  1. http request a(using http instead of rtp/rtsp)

so question is, need use ffmpeg h.264 stream or can ios api? if use ffmpeg encode h.264(libx264), how that, there sample code or guideline?

i've read post what's best way of live streaming iphone camera media server? it's pretty discussion, want know detail.

the license ffmpeg incompatible ios applications distributed through app store.

if want transfer realtime video , have kind of usable frame rate, won't want use http nor tcp.

i got following problem: i have object called tempscore game. this object blitted canvas renderer via copypixels method. object not display object. it's score-object (self made). score-object extends object called basicblitarrayobject. basicblitarrayobject extends eventdispatcher (therefore no display object). i tried apply several different tweenlite-plugins tempscore-object (i.e. transformaroundcenter, colormatrixfilter, etc.). nothing happens. absolutely nothing. sometimes error messages (when plugin requires display object , object not display object). far good. according greensock (maker of tweenlite) engine can tween numeric property of object. when plugin transformaroundcenter requires display object tweening have modify plugin working non-display object (tempscore). can't because it's way hard me. my game rests upon code: http://www.8bitrocket.com/book/ch11_blastermines.zip try apply tweenlite object called tempmine inside game class blastermines. ...
