  • 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" (...)

  • Can't decode HEVC video with DXVA2 and ffmpeg

    10 mai 2018, par Igor

    I can’t use DXVA2 hardware acceleration for decoding of HEVC video with ffmpeg. DXVA2 for H.264 works fine.

    I compiled an official example hw_decode.c from ffmpeg sources :

    https://github.com/FFmpeg/FFmpeg/blob/master/doc/examples/hw_decode.c

    When I call av_send_packet() it performs a callback assigned in AVCodecContext->get_format and returns only AV_PIX_FMT_YUV420P for HEVC video instead of AV_PIX_FMT_DXVA2_VLD for all H.264 videos. So HW decoding doesn’t work.

    Software decoding of HEVC works without problems.

    MPC-HC plays fine HEVC video with DXVA2 (CPU loading is low and Task Manager shows work of Video decoder in GPU details). My video card is Geforce 1060.

  • How can I prettify my compiled binary of FFmpeg ?

    2 avril 2019, par Hashim

    After many weeks and a lot of effort, I finally managed to use a Cygwin and MinGW-w64 toolchain to cross-compile a working binary of FFmpeg for Windows, complete with the superior but elusive fdk_aac encoder.

    However, comparing my newly-compiled binary with the official pre-compiled build for Windows makes me feel a little... lacking (first run is the Zeranoe build, second is my own) :

    enter image description here

    Notice how the Zeranoe build’s banner is missing all of the unseemly-looking configure options apart from the external libraries. Along with that, it also has the date that the program was built on inserted right after the GCC version.

    How were the compilers of this build able to add these enhancements to their binary, and how can I do the same ? I’m assuming these are simply GCC or preprocessor options that I can’t find any information on, or maybe there’s more to it than that.

    N.B : I’m aware of the --no-banner switch for FFmpeg, and that’s not what I’m trying to do here.

  • Flutter : How to use flutter_ffmpeg to add overlays like watermarks and texts to a video ?

    29 septembre 2022, par Ryan Wang

    I try to implement the video_editing feature to my app, and I'd tried the Tapioca Package and the Video_Manipulation package but found that they both do not meet my criteria, so I put my last hope on the flutter_ffmpeg package.

    


    But as I read through its official doc on pub.dev, not a thing on my mind but "WHAT THE HECK", I can't understand what those commands are used for, and though I can't find anything related to add widget overlays to a video. And almost no tutorial on the web that explains how to use it.

    


    So if you successfully implemented adding watermarks/texts to a video with the ffmpeg package, please show me how. Thanks !
