Multilang : améliorer l’interface pour les blocs multilingues
18 février 2011, parMultilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela. -

c# how to correctly format an ffmpeg user input stream ?
6 janvier 2021, par user14527374So I'm writing a c# application which allows a user to scale a video in pixels to a custom dimension. I am strugeling to get the user input from a textbox for the mpeg psi arguments :


Here is the code :


var localStoragePath = Path.Combine(Path.GetTempPath(), name);
 var directoryPath = Path.GetDirectoryName(localStoragePath);
 Directory.CreateDirectory(directoryPath);
 File.WriteAllBytes(localStoragePath, bytes);
 Progress.Text = ($"File copy successful: {File.Exists(localStoragePath)}");
 var readBack = File.ReadAllBytes(localStoragePath);
 Progress.Text = ($"Read file Back: {readBack.Length}, {localStoragePath}");
 var resizedFolderPath = @"C:\upscaledvideohere";
 Directory.CreateDirectory(resizedFolderPath);
 var resizedFiePath = Path.Combine(resizedFolderPath, Path.GetFileName(localStoragePath));

 var psi = new ProcessStartInfo();
 psi.FileName = @"C:\ffmpeg-2020-12-27-git-bff6fbead8-full_build\bin\ffmpeg.exe";
 psi.Arguments = $"-i \"{localStoragePath}\" -vf scale=" + pixelsheight.Text "\"{resizedFiePath}\"";
 psi.RedirectStandardOutput = false;
 psi.RedirectStandardError = false;
 psi.UseShellExecute = true;
 Progress.Text = ($"Args: {psi.Arguments}");



For


psi.Arguments = $"-i \"{localStoragePath}\" -vf scale=" + pixelsheight.Text "\"{resizedFiePath}\""



What would be the correct way to input the text for what the user typedin the pixelsheight text box ?


Thanks very much.

ffmpeg export without color loss
27 décembre 2020, par serI'm trying to add a watermark to a video through ffmpeg, but all the exports result in loss of color information. I would like to retain the same color information as the original video, how do I do that ?


Currently, I use this code :


./ffmpeg -i input.MOV -loop 1 -i logo.png -codec:v libx264 -crf 18 -preset medium -filter_complex "



I realised the only way to not lose the color information is to set -crf to 0 and -preset to veryslow, but it results in a really large file size. (2 times the size of original video, which is not effective)


I also get this error when I run ffpmeg :


[swscaler @ 0x117577000] deprecated pixel format used, make sure you did set range correctly



See Image comparison here — the blacks on the export were not as "black" as original
