  • Ajouter notes et légendes aux images

    7 février 2011, par

    Pour pouvoir ajouter notes et légendes aux images, la première étape est d’installer le plugin "Légendes".
    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

  • How to get frames from HDR video in scRGB color space ?

    5 mars 2018, par Виталий Синявский

    I want to create a simple video player that will show HDR video on HDR TV. For example, this "LG Chess HDR" video. It is encoded with HEVC, its bit depth is 10 bit, pixel format is YUV420P10LE and it has metadata abount BT2020 color space and PQ transfer function.

    In this NVIDIA article I found the next :

    The display driver takes the scRGB back buffer, and converts it to the
    standard expected by the display presently connected. In general, this
    means converting the color space from sRGB primaries to BT. 2020
    primaries, scaling to an appropriate level, and encoding with a
    mechanism like PQ. Also, possibly performing conversions like RGB to
    YCC if that display connection requires it.

    It means that my player should render pixels in the scRGB color space (linear encoding, sRGB primaries, full range is -0.5 through just less than +7.5). So I need to get frames from the source video in this color space somehow, preferably in FP16 pixel format (half float, 16 bits per one color channel). I come to the following simple pipeline to render videos to HDR :

    source HDR video in BT2020 color space with applied PQ -> [some video library] -> 
    
-> video frames with colors in scRGB color space -> [my program] ->
    
-> rendered video on HDR TV with applied conversions by display driver

    I’m trying to use FFmpeg as this library and do not understand how to get frames from the source HDR video in scRGB color space.

    I use sws_scale FFmpeg method now to get frames and know about filters API. But I did not found any information and help about how to transparantly get frames in scRGB using these functionality without parsing metadata for all source videos and create custom video filters for them.

    Please, tell me what I can do to get frames in the scRGB color space using FFmpeg. Can someone tell other libraries with which I can do it ?

  • -shortest is not working while looping audio with amovie in FFMPEG

    18 juin 2019, par Nikunj Paradva

    Here input is two video total 40 second, i am concate that and speed up 4x,then video duration is 10 second,

    audio input duration is dynamic it ll be shorter than video or bigger than video duration that’s why i am using amovie command for replace audio with looping to infinite, and add -shortest command at last.

    but it won’t be worked. it goes to infinite process.

    Here is my command

    [-y,
