• Unable to convert .mp3 to .m4a using ffmpeg [closed]

  4 mai 2013, par rahulg

  I am fully aware the legal constraints in using libfaac but this is just for my testing purpose.

  I have compiled ffmpeg with faac enabled. So when I tried to convert an .mp3 to a .m4a here is the error that I am getting. Please provide a resolution to this problem. I tried it on two different sources of .mp3, still I am getting the same error.

  Also while using Faac independently I get this weird error for any file.

• iPhone - IMA WAV ADPCM audio stream for iOS

  21 mai 2013, par Siriss

  I am trying to write an app for a school project that will play a video stream of the lab. They use Foscam cameras, and from what I understand they only stream audio in FFMPEG and VLC (a wrapper of FFMPEG and others, correct ?). I can play the video stream in a UIWebView just fine, but I can't figure out how to get audio to work. I have read a bunch of post on here about the different audio stream options, but none support this format. I have also looked into VLCKit, but that seems to only work in OS X, not iOS.

  Is there a Framework, or Kit that can stream IMA WAV ADPCM audio from a VLC/FFMPEG file, or does someone know of a better way to get audio from a Foscam ?

  EDIT - I know more about the stream and I have tried a few things. I tried AVPlayer, but discovered Audio FIle Stream and Audio Queue Services but can't find a good tutorial.

  I also found THIS site, and tried the project with my stream and it did not work.
