  • Menus personnalisés

    14 novembre 2010, par

    MediaSPIP utilise le plugin Menus pour gérer plusieurs menus configurables pour la navigation.
    Cela permet de laisser aux administrateurs de canaux la possibilité de configurer finement ces menus.
    Menus créés à l’initialisation du site
    Par défaut trois menus sont créés automatiquement à l’initialisation du site : Le menu principal ; Identifiant : barrenav ; Ce menu s’insère en général en haut de la page après le bloc d’entête, son identifiant le rend compatible avec les squelettes basés sur Zpip ; (...)

  • Android FFmpeg wrapper that can run https protocol

    19 février 2019, par Henderson

    I’m trying to deploy ffmpeg command on my android app.

    the command I’m gonna run is like

    ffmpeg -headers "X-Token:SOMETOKEN" -i https://streamthatiwannaget.com/player.m3u8 -acodec copy outputfile.m4a

    I tried libraries from bravobit’s and writingminds’s but the problem was both of them DO NOT support https protocol.

    Seems like openssl is required when compiling ffmpeg.

    But it’s really frustrating to building, writing Android.mk and JNI... so on.

    Is there any ffmpeg-android library that can deal with https protocol ?
    Or any idea helpful for this ? Thank you in advance.

  • Sharing AVPacket data in shared memory

    13 décembre 2023, par Salvo Passaro

    I'm redesigning an application (heavily based on FFmpeg) moving some of the video muxing to a separate process from where the demuxing happens.

    


    Until now I had a pool of threads doing demuxing work, producing AVPackets to be inserted in a queue to be later consumed by another pool of threads doing muxing work.

    


    Now, I'd like to maintain a shared memory approach for the AVPacket queueing between processes but I'm not sure how to properly allocate the internal AVPacket buffer in shared memory.

    


    IPC's probably gonna be enabled by something like this

    


  • Difference of pixel value between MATLAB and OpenCV extracting frames from video

    31 mai 2017, par Andrey Kosmachev

    I’m trying to open a video file encoded with H264 using Matlab. I rip the first frame, analyze the north-western square 9x9, I get the following matrix :

       116   128   126   126   127   126   127   126   130
    

    
   125   128   127   131   131   130   131   129   127
    

    
   147   150   150   152   157   151   157   152   149
    

    
   145   152   158   151   155   158   154   158   156
    

    
   145   155   157   155   154   161   152   158   154
    

    
   149   154   151   156   158   152   157   152   156
    

    
   151   152   155   152   158   151   155   150   151
    

    
   148   161   156   157   155   155   152   152   154
    

    
   150   157   150   152   151   149   151   156   155

    I try to do the same thing with OpenCV and have the following result :

       116   128   125   125   126   125   126   125   130 
    

    
   124   128   126   131   131   130   131   129   126 
    

    
   146   150   150   152   157   151   157   152   149 
    

    
   145   152   158   151   154   158   153   158   156 
    

    
   145   154   157   154   153   160   152   158   153 
    

    
   149   153   151   156   158   152   157   152   156 
    

    
   151   152   154   152   158   151   154   150   151 
    

    
   147   160   156   157   154   154   152   152   153 
    

    
   150   157   150   152   151   149   151   156   154

    It is seen that approximately in 50 percent of cases the brightness value of the pixel in the first matrix is one more than in the second one. For this reason, the results of further processing, respectively, in Matlab and OpenCV are different. Can someone explain to me, what is this effect related to and how to overcome it ?
