    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.
    Ces technologies permettent de distribuer vidéo et son à la fois sur des ordinateurs conventionnels (...)

  • What is causing "unspecified pixel format" and "Error opening filters !" error in ffmpeg ?

    19 février 2019, par SJAndersonLA

    I’m writing an mp4 to HLS transcoding process that works as intended on files smaller than 7 gigabytes (sample size is 100 videos). When attempting to transcode anything larger than 7GB, it crashes.

    The command :

    ffmpeg
     -i large_file.mp4 -y
     -vf scale=w=1920:h=1080:force_original_aspect_ratio=decrease
     -c:a aac

    The error says to try increasing analyzeduration and probesize, which I set to max value (based on an answer from this post), however that didn’t seem to change the behavior. I also suspected that the file was corrupted, but the fact that this is failing for all files larger than 7GB makes it more difficult to suggest its something not related to the size of the mp4.

  • need help on solving my ffmpeg command line

    3 avril 2019, par DRMTV

    i create a small bash script to encode 1080p video , the video will be added with watermark at bottom left and i need to add a black padding on top and bottom

    i tried several way but still no luck , i tried -vf and yes it worked but cant use padding and watermark together , and suggest use filter_complex

    if i use this code directly without bash script it work

    As I understand it libav has been replaced by ffmpeg but the build should still be able to reference the packages as libav. I’ve tried adding different paths to PKG_CONFIG_PATH using `export PKG_CONFIG_PATH=...’ but with no success. It is possible I’m not adding the correct path, I used ’dpkg -L ffmpeg’ to locate the package. The output of that is :

    ...of which I can assume the useful part is ’/usr/bin’ which i added to my PKG_CONFIG_PATH and still the same error when building. I am running Ubuntu 18.04 LTS. I’m at a loss and have been grinding at this for the past 2 days, any help would be GREATLY appreciated. Thank you and I’m happy to provide more needed information. As a small request, I am pretty new to Linux so if you could include as many details in command line operations as possible it would help alot.
