  • 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.

  • .h264 file cannot convert to .mp4 file by using ffmpeg

    21 janvier 2023, par Dr.Fail to fall asleep

    I have a car camera. Videos are HEVC codec but stored with .h264 file type.
    
I use ffmpeg to convert these .h264 file type to mp4 file type.

    


    Most of videos are converted successfully, some videos failed.

    


    some video convert successfully, some video failed

    


    What is weird is that this "convert-failed" video clip can be normally played by using the video player provided from video seller.
convert-failed video clip be played successfully

    


    I will upload two of these .h264 videos, one can be converted successfully, one cannot.

    


    Could anyone let me know how to finish the convert.

    


    see my ffmpeg command and output here

  • How can I know a certain file is a video file ?

    31 mai 2019, par Arthur Park

    I am trying to figure out if a certain user-uploaded file is a video file.

    I first tried ffprobe,

    # a png file
    

    
Input #0, png_pipe, from '<file>':
    
  Duration: N/A, bitrate: N/A
    
    Stream #0:0: Video: png, rgba(pc), 920x2094 [SAR 4724:4724 DAR 460:1047], 25 tbr, 25 tbn, 25 tbc
    

    
# a text file
    

    
Input #0, tty, from '<file>':
    
  Duration: 00:00:00.24, bitrate: 40 kb/s
    
    Stream #0:0: Video: ansi, pal8, 640x400, 25 fps, 25 tbr, 25 tbn, 25 tbc
    

    
# a video file
    

    
Input #0, matroska,webm, from '<file>':
    
  Metadata:
    
    encoder         : libebml v1.3.5 + libmatroska v1.4.8
    
    creation_time   : 2017-12-12T20:18:42.000000Z
    
  <redacted>
    
</redacted></file></file></file>

    but it’s too hard to figure out what’s what. Even image files and text files count as a video.

    Should I compare the output matroska,webm, with every codec ffmpeg supports or is there a better way to do this ?

  • FFmpeg file path exception like file name not found

    7 février 2018, par Sagar Hudge

    I am getting following exception on video trimming.

    video path : /storage/emulated/0/Pictures/Instagram/Fast &amp; Furious 7 - Get Low Extended Version Video.mp4

    file name : Fast &amp; Furious 7 - Get Low Extended Version Video.mp4

    and ffmpeg searching for only Fast in

    /storage/emulated/0/Pictures/Instagram/Fast: No such file or directory

    I have found the issue ,it is causing due to the file name having spaces in between them you can check in above mentioned path and in exception.

    after changing file name its working but changing name of every file from device its not the right way so how can I solve this exception
