  • Qualité du média après traitement

    21 juin 2013, par

    Le bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?
    Plus la qualité du média est importante, plus la bande passante sera utilisée. Le visiteur avec une connexion internet à petit débit devra attendre plus longtemps. Inversement plus, la qualité du média est pauvre et donc le média devient dégradé voire (...)

  • TV audio extracted using ffmeg does not work in iOS (but it works in the simulator)

    26 janvier 2014, par Genar

    I can process a TV signal (well I have a .ts video which comes from a TV channel), using ffmpeg but the audio cannot be understood in an iPhone/iPad. The most strange is that the audio (and video) works properly in the simulator (and also in an Android real device, but this is another point), but in a real iPhone/iPad device the video is OK but the audio sounds like a metallic box and nothing can be understood.

    I have created the ffmpeg libraries for iOS (I have tried the version 2.0.2 and also the version 2.1.3) using the information provided in the following link :

    Installing ffmpeg ios libraries armv7, armv7s, i386 and universal on Mac with 10.8

    The aforementioned link explains how to create the ffmpeg include folders and the universal libraries which I have included into my project (the libraries created are : libavcodec.a, libavdevice.a, libavfilter.a, libavformat.a, libavresample.a, libavutil.a, libswresample.a and libswscale.a).

    The sampling frequency used is 48000.

    The audio got from ffmpeg is then stored into a buffer and then "inserted" using OpenAL ; but, from the same TV content (the same .ts video file) the audio data which is generated from ffmpeg in an iPhone/iPad is totally different from the audio data generated from ffmpeg in the simulator (which can reproduce both the audio and video perfectly).

    Thanks in advance,

  • How do I access the ipod-library for decoding ffmpeg ?

    16 janvier 2014, par M_On

    Thank you to look at my question.

    There is a problem with too slow to access the music file using ffmpeg.

    Get the URL of the music that is in the ipod-library by using the 'valueForProperty:MPMediaItemPropertyAssetURL' method.

    Use the (AVAssetExportSession Class) TSLibraryImport.m, extract the music files from ipod-library.

    However, I took the extraction time is too long. (4 seconds of the 3GS iPhone, iPhone 5 is 1 second)

    It was not possible to be decoded using FFmpeg If you do not the Export.

    In order to use FFmpeg, it's AVPlayer can not be used.

    I will never forget the grace if you can answer if you folded to know how other maybe.
