  • Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur

    8 February 2011, by

    La visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
    Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

  • Implementing custom h264 quantization for Ffmpeg?

    27 February 2017, by user2989813

    I have a Raspberry Pi, and I’m livestreaming using FFmpeg. Unfortunately my wifi signal varies over the course of my stream. I’m currently using raspivid to send h264 encoded video to the stream. I have set a constant resolution and FPS, but have not set bitrate nor quantization, so they are variable.

    However, the issue is that the quantization doesn’t vary enough for my needs. If my wifi signal drops, my ffmpeg streaming speed will dip below 1.0x to 0.95xish for minutes, but my bitrate drops so slowly that ffmpeg can never make it back to 1.0x. As a result my stream will run into problems and start buffering.

    I would like the following to happen:
    If Ffmpeg (my stream command)’s reported speed goes below 1.0x (slower than realtime streaming), then increase quantization compression (lower bitrate) exponentially until Ffmpeg speed stabilizes at 1.0x. Prioritize stabilizing at 1.0x as quickly as possible.

    My understanding is that the quantization logic Ffmpeg is using should be in the h264 encoder, but I can’t find any mention of quantization at all in this github: https://github.com/cisco/openh264
    My knowledge of h264 is almost zilch, so I’m trying to figure out

    A) How does h264 currently vary the quantization during my stream, if at all?

    B) Where is that code?

    C) How hard is it for me to implement what I’m describing?

    Thanks in advance!!

  • How to add .Net Standard Nuget package into .Net 4.5 Framework Project?

    16 July 2022, by Arjun Natarajan

    I am trying to install https://www.nuget.org/packages/FFMpegCore/4.8.0#dependencies-body-tab (FFMpegCore) Nuget package in my .Net 4.5 Console project. But unfortunately, getting the below error

    


    


    Error NU1202 Package FFMpegCore 4.8.0 is not compatible with net45 (.NETFramework,Version=v4.5) / win-x86. Package FFMpegCore 4.8.0 supports: netstandard2.0 (.NETStandard,Version=v2.0) ScreenCapturer C:\source\repos\ScreenCapturer\ScreenCapturer.csproj 1

    


    


    Actually trying to stream .png images to FFmpeg input pipe & then convert them as a video.

    


    P.S: Kind of new to this FFMpeg as well. So any help would be appreciated.
