  • 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 : Convert a legally purchased video on Google

    24 avril 2020, par Heycava

    I've bought a video on the Google Play Store. I need to have it on my computer in order to edit it for a video montage. But Google says "Important : You cannot download movies and TV shows onto a PC, Mac, and other laptops or computers."

    



    The video has a YouTube link. As I paid for it, I can watch it. I've managed to get the video part and the audio thanks to some web tools.
The video is a .webm file and the audio a .m4a file.

    



    I can hear the audio with VLC but I can't watch the video. Even if VLC displays "21:42" for the timecode.

    



    Here are informations for the webm file (from MediaInfo) :

    It seems to be a good video file.

    



    I wanted to convert it with some video converters but none of them works. So I've tried to download ffmpeg, I renamed the video to "video.webm" and tried a lot of commands. But none of them worked.

    



    Here are informations from ffprobe command :

    I've already checked on the Internet solutions for the raised issues :

    



      

    • Invalid frame marker

      • 


    • unspecified pixel format

      • 


    • Consider increasing the value for the 'analyzeduration' and 'probesize' options

      • 


    



    But it didn't work in my case.

    



    Obviously, I can watch the video on YouTube when I'm logged into my purchase account. I presume they have a high level security algorithm, that's why I can't do nothing. Mayve there is something with the "enc_key_id" in the metadata, they get it and the video can only be read with it. I don't know.

    



    I find it unacceptable not to be able to use freely my purchased videos.

    



    Would anyone have an idea ?

    


  • ffmpeg overlay timing issue

    22 avril 2020, par Mario Iannotta

    I'm trying to add a png as overlay to a mov video with ffmpeg (version 4.2.2) using the following command :

    



    ffmpeg -i ./input.mov -i ./overlay.png -y -filter_complex "overlay=enable='between(t,1,4)'" ./output.mp4

    



    Now my understanding of overlay=enable='between(t,1,4) is that the overlay will be added at one second and will be removed at 4 seconds since the begin of the video but the output is somehow different.

    



    The overlay is added at roughly 2:66 and it is removed at 5:14.

    



    Trying with different values result in even more confusing outputs.

    



    eg :

    



      


    • between(t,3,10) —> 3:12 | 11:05

      • 


    • between(t,2,7) —> 2:65 | 7:22

      • 


    • between(t,1,2) —> the overlay is not added ad all

      • 


    



    The metadata of the input video are the following

    



      Metadata:
    major_brand     : qt

      encoder         : H.264


    



    I also tried to convert the video to mp4 (with ffmpeg -i input.mov -vcodec copy -acodec copy out.mp4) before applying the overlay but the issue is still there.

    



    Edit : I downloaded a test mp4 video and the command is working as expected so it is definitely something wrong with my input video. Any idea what it is ?

    



    Edit 2 : Here's the output of ffmpeg command :

  • FFMPEG "Could find no file with path" and "No such file or directory"

    4 mai 2020, par bmw_58

    I try to convert a sequence of pictures to video file.

    Does someone have a solution for it ?
