  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • FFMPEG can't generate 1920×1080 video

    4 juillet 2017, par Alex

    I’m trying to generate a dummy video with ffmpeg with 1920×1080 size. Ffmpeg seems to not work with this size but it works fine with 1280x720 and with 3840×2160

    The error message is the following :

    [testsrc @ 0x7f95e3d13da0] Unable to parse option value "1920×1080" as image size
    
Last message repeated 1 times
    
[testsrc @ 0x7f95e3d13da0] Error setting option size to value 1920×1080.
    
[Parsed_testsrc_0 @ 0x7f95e3d13cc0] Error applying options to the filter.
    
[lavfi @ 0x7f95e6000000] Error initializing filter 'testsrc' with args 'duration=30:size=1920×1080:rate=23.976'
    
testsrc=duration=30:size=1920×1080:rate=23.976: Invalid argument

    And I’m using this cmd line arguments :

    ffmpeg -f lavfi -i testsrc=duration=30:size=1920×1080:rate=23.976 -vcodec h264 test_video.mov

    Changing the frame rate does not solve the problem.

    I have ffmpeg version 3.3.2 on OSX el capitan

    Am I missing something ?

  • How do I upscale an iOS App Preview video to 1080 x 1920 ? [closed]

    12 avril 2024, par Benjamin Thiel

    I just captured a video of my new app running on an iPhone 6 using QuickTime Player and a Lightning cable. Afterwards I created an App Preview project in iMovie, exported it and could successfully upload it to iTunes Connect.

    



    Apple requires developers to upload App Previews in different resolutions dependent on screen size, namely :

    



      

    • iPhone 5(S) : 1080 x 1920 or 640 x 1136

      • 


    • iPhone 6 : 750 x 1334 (what I have)

      • 


    • iPhone 6+ : 1080 x 1920

      • 


    



    Obviously, 1080 x 1920 is killing two birds with one stone. I know that upscaling isn't the perfect solution, but it's meeting my needs. Since I don't own a 6+, another recording session won't do the trick.

    



    Unfortunately, iTunes Connect is extremely picky about what to accept. Here's what I tried, to no avail :

    



      

    • Handbrake, iMovie, QuickTime do not support upscaling

      • 


    • MPEG Streamclip

      • 


    • ffmpeg -i input.mp4 -acodec copy -vf scale=1080:1920 output.mp4

      • 


    



    Strangely enough, iTunes Connect keeps complaining about the wrong resolution when I try to upload the output.mp4 of ffmpeg.
