  • 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" (...)

  • Encoding for HLS using FFMPEG results in have a decreasing DTS

    29 décembre 2014, par Luuk D. Jansen

    I am trying to encode video for HTS live streaming, but am having problems with validating the stream using Apple Media Validator (mediastreamvalidator).
    (my test file : http://dominicansinteractive.idoms.org/media/9536/playlist.m3u8)

    The output is :

    --------------------------------------------------------------------------------
    
http://dominicansinteractive.idoms.org/media/9536/199/prog_index.m3u8
    
--------------------------------------------------------------------------------

segment_00000.ts:
    

    
    ERROR: (-1) Decreasing DTS were detected in track 0
    
    ERROR: (-1) Decreasing DTS were detected in track 1

    Average segment bitrate: 2155094.67 bps
    
    Average segment structural overhead: 206525.83 bps (9.58 %)

    The second segment doesn’t seem to have the problem :

    This seems to be a serious problem for HLS, so I am looking if there is a way to fix this.

    When looking with FFMPEG at the encoded file I get (encoder output/command at the bottom of the email) :

  • How to integrate Netflix audio isma and video ismv files into a single file ?

    25 juillet 2012, par Ωmega

    Having Netflix audio .isma file and video .ismv file, how can be those separate files be integrated into a single .mp4 or .flv file ? Is there some schema or algorithm that can be used to develop such a tool, or is there already a tool available ?

    I tried to use ffmpeg as follows :

    # ffmpeg -i in.isma -i in.ismv out.mp4

    Even there is no audio error shown in the above response, I was unable to convert the single audio .isma file into mp3 or other audio format file. I assume these isma/ismv files are somehow crypted or encoded in non-standard format. Below is a partial dump of audio file.

  • How to configure ffmpeg on ubuntu to convert *.3gp to pcm *.wav ? [migrated]

    31 juillet 2012, par Monica Sol

    I'm using linux Ubuntu ver 10.04.
    I need to convert file *.3gp to PCM *.wav. I'm using for that ffmpeg program.

    When it's installed from repository by using aptitude install ffmpeg it's installing some basic version of it and I cannot convert what I need.

    I've read some stuff on the Internet and I've made what there was written.
    I've installed the latest yasm ver.1.1.0 and the newest x264 - 0.125.2208. After that I got ffmpeg using git from http://ffmpeg.org/download.html (git clone git ://source.ffmpeg.org/ffmpeg.git ffmpeg).

    I`ve tried to configure ffmpeg by myself using :

    ./configure --enable-gpl --enable-version3 --enable-postproc 
    
--enable-nonfree --enable-swscale --enable-pthreads --enable-libmp3lame 
    
--enable-libx264 --enable-libopencore-amrnb --enable-libopencore-amrwb

    than : time make && make install.

    Till this time everything was ok. After conversion (ffmpeg -i audiotest.3gp -f s16le -ar 8000 -acodec pcm_s16le audio.wav) I wanted to check information about this PCM *.wav file (ffmpeg -i audio.wav) and I`ve got this error :

    ~# ffmpeg -i audio.wav

    Can anyone help me with this ? What I'm doing wrong ? I'm linux newbie, but I really need to get this thing works.
