  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible.

  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Ffmpeg how to encode mpg into 2 channel aac ?

    1er août 2012, par Richard Knop

    This command will of course work :

    avconv -i input.mpg -c:v libx264 -s 852x480 -c:a libfaac output.mp4

    But that encodes the mpg into a file with these audio settings :

        {
    
        "index": 1,
    
        "codec_name": "mp2",
    
        "codec_long_name": "MP2 (MPEG audio layer 2)",
    
        "codec_type": "audio",
    
        "codec_time_base": "1/48000",
    
        "codec_tag_string": "mp4a",
    
        "codec_tag": "0x6134706d",
    
        "sample_fmt": "s16",
    
        "sample_rate": "48000",
    
        "channels": 2,
    
        "bits_per_sample": 0,
    
        "r_frame_rate": "0/0",
    
        "avg_frame_rate": "0/0",
    
        "time_base": "1/48000",
    
        "start_time": "0.000000",
    
        "duration": "60.000000",
    
        "nb_frames": "2500",
    
        "tags": {
    
            "language": "und",
    
            "handler_name": ""
    
        }
    
    }

    This is what I need :

    Resolution: 480p
    
Ratio: 1.78
    
Audio: 2 channel AAC
    
Video Bitrates: 600 / 800 / 1200 / 2000
    
Audio Bitrates: 96
    
Codec: H.264 - High

    I tried :

    avconv -i input.mpg -c:v libx264 -s 852x480 -c:a libfaac output.mp4

    But I get error :

    Unknown encoder 'libfaac'

    Even after I installed libfaac-dev like this :

    sudo apt-get install libfaac-dev
