Demande de création d’un canal
12 mars 2010, parEn fonction de la configuration de la plateforme, l’utilisateur peu avoir à sa disposition deux méthodes différentes de demande de création de canal. La première est au moment de son inscription, la seconde, après son inscription en remplissant un formulaire de demande.
Les deux manières demandent les mêmes choses fonctionnent à peu près de la même manière, le futur utilisateur doit remplir une série de champ de formulaire permettant tout d’abord aux administrateurs d’avoir des informations quant à (...) -
Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur
8 février 2011, parLa 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".

Concatenating video using FFMPEG wrapper class [duplicate]
21 décembre 2017, par alan samuelThis question already has an answer here :
I am trying to concatenate video using NReco.VideoConverter wrapper class made for FFMPEG.
I have three video files with the same frame rate and same frame size.
Here is what I have done.
string toconcatfile = @"C:\Users\Alan\Desktop\Black.mp4";
string output1 = @"C:\Users\Alan\Desktop\output1.mp4";
string output2 = @"C:\Users\Alan\Desktop\output2.mp4";
string finaloutput = @"C:\Users\Alan\Desktop\finaloutput.mp4";All the three videos have a frame rate of 25 and Video frame size yet it fails when I add in toconcatfile to the final conversion method.
It works when its just output1 and output2 meaning there must be a different setting in toconcatfile.
Here is what I have tried.
FFMpegConverter fFMpeg = new FFMpegConverter();
//Slices first video
ConvertSettings settings = new ConvertSettings
{
VideoFrameRate = 25,
VideoFrameSize = FrameSize.hd480,
MaxDuration = startcut,
AudioSampleRate = 44100
};
//Slices second video
ConvertSettings settings2 = new ConvertSettings
{
VideoFrameRate = 25,
VideoFrameSize = FrameSize.hd480,
Seek = endcut,
AudioSampleRate = 44100
};
//Copies framerate and size from the previous video to the concatenation video
ConvertSettings settings3 = new ConvertSettings
{
VideoFrameRate = 25,
VideoFrameSize = FrameSize.hd480,
MaxDuration = 4,
AppendSilentAudioStream = true,
AudioSampleRate = 44100
};
string newblack = @"C:\Users\Alan\Desktop\newblack.mp4";
//Slice method called
fFMpeg.ConvertMedia(pathtofile, Format.mp4, output1, Format.mp4, settings);
fFMpeg.ConvertMedia(pathtofile, Format.mp4, output2, Format.mp4, settings2);
fFMpeg.ConvertMedia(toconcatfile, Format.mp4, newblack, Format.mp4, settings3);
String[] inputfiles = new String[2];
inputfiles[0] = output1;
inputfiles[1] = newblack;
//inputfiles[1] = output2;
ConcatSettings concatSettings = new ConcatSettings
{
//CustomOutputArgs = output1+" "+ toconcatfile+ " "+output2+ " -filter_complex \"[0:v:0][0:a:0][1:v:0][1:a:0][2:v:0][2:a:0]concat=n=3:v=1:a=1[outv][outa]\" -map \"[outv]\" - map \"[outa]\""
};
fFMpeg.ConcatMedia(inputfiles, finaloutput, Format.mp4, concatSettings);Can anyone help ?
Edit : I get the exception message - "Invalid argument (exit code : 1)",
Here is the output log of FFMPEG

what is the filter of my FFMPEG scaling command ?
15 décembre 2017, par AtrinI have upscaled and downscaled an image with following command.
ffmpeg -s:v 1280:720 -r 25 -i input.yuv -vf scale=1920x1080 -c:v rawvideo -pix_fmt yuv420p out.yuvI’m wondering what kind of filter is used to do down scaling (linear, bicubic,...) ?
and how can I change the filter or add it if there is no filter in this command ?
