• is it possible to play h264-mpegts format in ios ?

  11 octobre 2012, par jAckOdE

  Server transcodes the video to the h264/aac, and send video data to client simultaneously. To play and save the video data at the same time, I use mpegts as the container format, but the problem is that ios MediaPlayer can not play mpegts file.

  Google said that i can used ios-build of ffmpeg to do the task, but it seem to be an overkill. is there any other ways to play mpegts in iphone using just iOS SDK ?

• Audio conversion of CAF file

  13 février 2017, par John

  I am recording audio on the iPhone to a CAF file with kAudioFormatiLBC, the recording works fine.

  I want to be able to take a sample and also get it to convert to other formats after I have uploaded it to by ruby on rails webservice.

  I am trying to use sox but get :

  sox in.caf out.mp3<br /><br />
sox FAIL formats: can't open input file `in.caf': Supported file format but unsupported encoding.

  Similar with ffmpeg I get :

  Unable to find a suitable output format for 'in.caf'

  Any ideas ?

  Thanks

• RTSP/RTMP Video Streaming Client iOS [closed]

  28 mai 2015, par nathansizemore

  I’m in need of a open source solution/library to stream RTSP/RTMP to an iOS Application. I need to build an app that connects to a media server, and opens the provided video stream. I believe there has to be libraries out there, but I have yet to find one that is open source, compiles, actually works, and runs on iOS 5+, iPhone 4+. I do not have a preference, RTMP or RTSP will suffice. Preferably the one with the least amount of work. I have RTSP working on the Android side, but nothing for iOS yet.

  This is what I already know from research today -

  RTSP

  • Seems possible using Live555/FFMPEG
  • MooncatVenture Group - Old FFMPEG, not compatible with ARMv7s (No updates/blogs/commits in over a year)
  • DFURTSPPlayer - This is a working example.

  RTMP

  • Seems possible using Live555/FFMPEG
  • A few libraries are out there for data messaging, but that is all
  • MidnightCoders Project - Does not seem video support is build yet, as Audio is not.

  I’ve never messed with anything video related before, so encoding, frame rate, key frame, chunks, etc... is pretty foreign to me. Right now, it seems building a static binary from Live555/FFMPEG is the only solution to my problem. If so, can anyone give me a simple quickstart guide or links to a blog/example someone has out there ? I’m not looking for anything crazy, just a simple

  1. Download This - LINK
  2. Compile it like this - LINK
  3. Place it into X Folder in Xcode
  4. Create X Object
  5. Read Stream API here - LINK

  If not, anyone want to point me to a working open source library ?

  Oh yeah, this happens to be my first iPhone app and first time in Objective-C. Awesome first project, yeah ?
