  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • ffmpeg : create video from images [duplicate]

    22 juillet 2021, par zuluk

    I am trying to create a video from my images on my Windows 10. The images are named lu_1.jpg, lu_2.jpg and so on up to 1000. Now I tried this code in a .bat file to get the video :

    


    ffmpeg -framerate 1 -i lu-%d.jpg -c:v libx264 -r 30 ../lu_output.mp4


    


    Unfortunately I get the following error from cmd :

    


    lu-v: No such file or directory


    


    The .bat file is placed in the same folder as the images.

    


    Could someoene please tell me how to solve this issue ? Thanks in advance.

    


  • Is there a need to apply Deblocking filter, when I have all Intra frames Encoding

    31 août 2015, par Codec Guy

    I am working on H.264 Deblocking Filter and need some clarity.

    • While designing an all Intra Encoder and Decoder, is it mandatory to
      add Deblocking Filter block in the Codec.
    • If deblocking filter is not enabled for all Intra Encoding does that
      cause any PSNR degradation(I checked few streams the PSNR almost
      remained the same).
    • If I am encoding all my frames using Intra prediction, does that also
      have any blocking artifacts.

    Thanks in advance

  • Embedding Metadata to H.264 encoded file

    7 septembre 2012, par kerim yucel

    I am currently developing an application which produces certain metadata with respect to preview frames coming from the camera. I can see this metadata being produced properly and I have no problems here.

    However, I have to embed this metadata to these frames of interest (frames are processed by a native algorithm to produce this metadata). I am using ffmpeg with x264 to encode the frames into H.264. I have checked x264.h and some documentations but failed to find what I seek.

    My question is ; is there any unused portion of H.264 syntax that I can embed my metadata to encoded frames ?

    I hope I was clear enough. Thanks in advance.
