  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • Encoding and processing into web-friendly formats

    MediaSPIP automatically converts uploaded files to internet-compatible formats.
    Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
    Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
    Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
    All uploaded files are stored online in their original format, so you can (...)

  • CentOS 7.4.1708 : ERROR : x265 not found using pkg-config

    16 novembre 2017, par Adrian

    I’m trying to compile ffmpeg with Nvidia support following the guides on https://trac.ffmpeg.org/wiki/CompilationGuide/Centos and https://developer.nvidia.com/ffmpeg. I’ve ended up with the following command :

    PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure --enable-pthreads --disable-w32threads --prefix="$HOME/ffmpeg_build"   --pkg-config-flags="--static"   --extra-cflags="-I$HOME/ffmpeg_build/include -I/usr/local/cuda/include"   --extra-ldflags="-L$HOME/ffmpeg_build/lib -L/usr/local/cuda/lib64"   --extra-libs='-lpthread -lm'   --bindir="$HOME/bin"   --enable-gpl   --enable-libfdk_aac   --enable-libfreetype   --enable-libmp3lame   --enable-libopus   --enable-libvorbis   --enable-libvpx   --enable-libx264  --enable-libx265    --enable-nonfree --enable-cuda --enable-cuvid --enable-nvenc --enable-nonfree --enable-libnpp

    I’m getting the wonderful error

    gcc version is gcc-4.8.5-16.el7.x86_64

    As per a question below : Yes - x265 is installed as per https://trac.ffmpeg.org/wiki/CompilationGuide/Centos and yes pkg-config is finding it. The compilation error makes me think that I’m missing a flag to the —pkg-config-flags optnion, but I can’t find one that works.

    Does anyone know what I should be passing to pkg-config to get it to enable x265 ?

  • Error trying to decode 4K video using NVDEC

    19 avril 2024, par Nestoraj

    I am trying to convert a 4K HEVC MKV file of 70GB into another HECV file but with less size. I am using FFmpeg with Nvidia acceleration but when I execute the following command an error appears :

    



    ffmpeg -y -vsync 0 -hwaccel_device 0 -hwaccel cuvid -c:v hevc_cuvid -i input.mkv -c:a copy -c:v hevc_nvenc -preset slow -b:v 10M -bufsize 10M -maxrate 15M -qmin 0 -g 250 -bf 2 -temporal-aq 1 -rc-lookahead 20 -i_qfactor 0.75 -b_qfactor 1.1 output.mkv


    



    The error is :

    



    [hevc_nvenc @ 0000021036b0d000] Provided device doesn't support required NVENC features
Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height


    



    The video file has these details :

    



    enter image description here

    



    It seems that FFmpeg cannot recognize my GPU as a supported device to decode but I have read that Nvidia has support for my card with NVDEC.

    



    I am running Windows 10 64 bits with i7 4790 and GTX 1080

    


  • avcodec : Implement vc1 nvdec hwaccel

    avcodec : Implement vc1 nvdec hwaccel

    This hwaccel is interesting because it also works for wmv3/9 content,
    
which is not supported by the nvidia parser used by cuviddec.
