  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    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.

  • FFMPEG 0.6.5 Commands

    10 novembre 2015, par j.edga

    I need to use ffmpeg version 0.6.5 for doings things like

    • transcribing to different formats ;
    • changing the quality ;
    • taking a still-frame shot ;
    • get the total video durations

    amongst other things.

    I have tried a couple of commands, but they don’t work. How can I do what I want to ?

  • FFmpeg adding 0.05 seconds of silence to transcoded AAC file ?

    29 octobre 2015, par FTLRalph

    In Java, I’m using FFmpeg to convert a WAV file to AAC with the function :

    -i input.wav -ac 1 -ab 64000 -ar 22050 output.aac

    When I open these two files in Audacity, I can clearly see that the AAC file is 0.05 seconds longer, with 0.05 seconds of silence added to the beginning.

    This is an issue when I try to mux this AAC file with a video file - the audio doesn’t sync up.

    Is there some sort of parameter to prevent this behavior or another way to get around this issue ?


    Edit - Console output while running the function :

  • ffmpeg-mp4box-mpeg dash plays only few segments

    30 octobre 2015, par Idris

    Need help in debugging the segment dash files

    The input was an MP4 with these details. This was recorded from a video camera, the output from the camera was mkv and we converted into MP4 after editing the audio via adobe

    • Size : 7.51 GB Frame rate : 25 frames/ second
    • Data rate : 25326kbps
    • Total bitrate : 25525kbps

    Converted this to another mp4 with this command

    ffmpeg -i "input.mp4" -s 1280x720 -c:v libx264 -b:v 750k -bf 2 -g 75 -sc_threshold 0 -an video_1280x720_750k.mp4

    ffmpeg -i "input.mp4"  -c:a aac -strict experimental -b:a 96k -ar 32000 -vn audio_96k.mp4

    The output video has

    • fps : 25
    • Data rate : 761kbps
    • bitrate : 761kbps

    Then, created the segmented dash through MP4Box

    MP4Box -dash 10000 -frag 10000 -rap -segment-name video_0_1280000\segment_ video_1280x720_750k.mp4

    MP4Box -dash 3000 -frag 10000 -rap -segment-name audio_0_96000\segment_ audio_96k.mp4

    The MPD generated was validated online and its perfect

    Played the video through dashjs.. I believe it just plays the initial segment and errors out as MEDIA_ERR_DECODE..MEDIA_ERR_SRC_NOT_SUPPORTED.. or some message which says start not found..

    Through chrome debugging I see that atleast 4 segments are correctly loading.. I am not sure whats going on..

    Any help in debugging the issue is really appreciated. I really can’t understand if this is a problem with the file or ffmpeg or mp4box or chrome.
