• Live Video Chat for iPhone and HTTP Live Streaming

  2 novembre 2014, par mayuur

  So generally, I want to make an app which has video chat functionality for iPhone. But after many searches, I am still not able to find any successful results. Is there any public or even for that matter, private API available for doing this on iPhone ??? If you have an YES answer, please help me.

  Basically, what I want is to read the streams of the video on both the devices connected for chatting. Thanks a lot in advance and please help me if you can.

  p.s - I have already checked iDoubs but it failed and always shows some unknown problem and for that reason, doesn’t allow me to connect to anyone.

  ALSO : The suggested method I have found is via HTTP Live Streaming. But, in that too, I have multiple doubts.

  1.) I need to find how do I upload my video from iPhone to the HTTP server from where I would be broadcasting ?

  2.) Can you please post something related to setting up the server ? How do I feed the video to the FFMPEG Server ?

  Mainly, I need to find the upload method. I am right now simply sending hex-code in the form of NSDATA to the server and I am stuck there. The main problem is, It is live. How do I handle that ?

  It would be best, if you could help me make the iDoubs work properly.

  Thank you so much for any kind of support !

• How to deal ffplay being too slow playing iPhone's videos ?

  8 janvier 2020, par Mikhail T.

  Trying to play a 3840x2160 video recorded by an iPhone 7 (@30fps), I get frequent pauses — in the video, music keeps playing.

  



  This happens both in firefox and when ffplay is invoked to play the file directly — from command-line. The CPU is a dual E6700 @3.20GHz — not super fast, but it should be able to play smoothly, shouldn't it ? Video is Intel's "series 4" integrated chipset — again, not a speed-daemon, but it should be adequate... Support for Intel's VA API is included.

  



  I build ffmpeg-4.1 from source using FreeBSD port. As you can see, the port has a maddening amount of options — including several different ones for the 264-codec.

  



  Any suggestions for improving the decoding speed to the point, where it is watchable by a human ? Thank you !
