  • (Dés)Activation de fonctionnalités (plugins)

    18 février 2011, par

    Pour gérer l’ajout et la suppression de fonctionnalités supplémentaires (ou plugins), MediaSPIP utilise à partir de la version 0.2 SVP.

  • ffmpeg : "Error setting profile"

    26 février 2017, par P. Reid

    I’ve been having trouble using ffmpeg to compress videos to something readable by quicktime. My goal in the end is to have a simple command that I can use to compress high bitrate videos (ie screencaptures) to something more reasonable to be able to share them with people.

    I want to use a command I found here as a starting point :

    ffmpeg -i input-file.avi -codec:v libx264 -profile: high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale=-1:480 -threads 0 -codec:a libfdk_aac -b:a 128k output_file.mp4

    Unfortunately I get this error :

    [libx264 @ 0x7f92ab81c200] Error setting profile high.
    
[libx264 @ 0x7f92ab81c200] Possible profiles: baseline main high high10 high422 high444
    
Stream mapping:
    
  Stream #0:0 -> #0:0 (rawvideo (native) -> h264 (libx264))
    
Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height

    If I take out the -profile: high the command functions but the output still doesn’t open in quicktime (it does in VLC). I can’t find the keyword -profile on the ffmpeg man page : https://ffmpeg.org/ffmpeg.html so I don’t know if this is important or what to do about it.

    Does anyone know what might be causing my problem ? What should I do to try and debug this problem ? I would describe myself as inexperienced so sorry if I’m missing something obvious.

    Thanks in advance for your help,
    Peter

  • FFMPEG - adding a nullsrc causes my script to report "1000 duplicate frames"

    14 juin 2020, par rossmcm

    I'm trying to add coloured rectangle highlights to a video, appearing at different locations and times. The highlights are on a 6x6 grid of 320x180 rectangles.

    



    Originally I didn't have the nullsrc=size=1920x1080 thinking that it would start with an empty image, but it seems that that causes it to make assumptions about where the input is coming from. So I added the nullsrc=size=1920x1080 to start with a transparent 1920x1080 image but this command returns a warning that 1000 duplicate frames have been produced and it keeps going past the end of the input video with no signs of stopping.

    9 avril 2020, par Pradeep Simba

    I make a video recorder android app with javacv.
But, when i run this app this error occurs "java.lang.NoClassDefFoundError : org.bytedeco.javacpp.avutil".
