  • Multilang : améliorer l’interface pour les blocs multilingues

    18 February 2011, by

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • HTML5 audio and video support

    13 April 2011, by

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.

  • Audio is lost on transcoding from DTS to AAC

    18 October 2015, by cirko

    On a Synology drive, I’m trying to transcode audio in an .MKV file from DTS to AAC using the native ffmpeg encoder. But without any error message (at least I don’t recognize any here), the audio stream is just missing in the output files. I tried it on several different files, all with the same result, leading to the conclusion that either I’m unable to see the error or something’s wrong with FFMPEG. I used the standard FFMPEG package provided with OPKG.
    This is the output I usually get:

    CirkosDaten> ffmpeg -i encodertest.mkv -map 0 -c:v copy -c:s copy -c:a aac 
    
-strict experimental output.mkv

    When I additionally set the bitrate, the output says

    Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 
    
(output.mkv) has not been used for any stream. The most likely reason is 
    
either wrong type (e.g. a video option with no video streams) or that it is 
    
a private option of some encoder which was not actually used for any stream.

    This indicates that somehow the 5.1, 48kHz DTS stream isn’t considered as an input. Why?

    EDIT: Is it possible that DTS decoding is turned off somewhere here? I reckoned maybe that’s why I get no errors. But I didn’t see any obvious option for that in the output.

  • FFmpeg buildpack for Heroku does not support ogg. Unknown encoder 'libvorbis'

    3 October 2015, by Matthew Slaton

    After some work, I was finally able to get the buildpack installed on Heroku. I ran into this error:

    Stream #0:0: Audio: pcm_u8 ([1][0][0][0] / 0x0001), 22050 Hz, mono, u8, 176 kb/s
    

    
2015-10-03T01:15:59.635036+00:00 app[web.1]: -t is not an input option, 
    
    keeping it for the next output; consider fixing your command line.
    
2015-10-03T01:15:59.635055+00:00 app[web.1]: Please use -q:a or -q:v, -qscale is ambiguous
    
2015-10-03T01:15:59.635479+00:00 app[web.1]: Unknown encoder 'libvorbis'

    My code is:

    ffmpeg -t 15 -i #{current_path} -acodec libvorbis -qscale 1 #{temp_path}

    The -t option is supposed to be for seconds and libvorbis is for ogg conversion.

    ffmpeg -version returns this:

  • Not converting flv file to mp4 file using ffmpeg

    4 October 2015, by Sandeep Nambiar
