Installation en mode ferme
4 février 2011, parLe mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
C’est la méthode que nous utilisons sur cette même plateforme.
L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...) -

How to write ffmpeg windows command for file path inside double quotes option
19 février 2021, par Herahadi Anplease help


I want to use ffmpeg for my c # application but an error appears


this is my code


videoPath = @"c:\location\in.mp4";
tempVideoPath = @"c:\another_location\out.mp4";

process.StartInfo.FileName = @"ffmpeg.exe";
 
process.StartInfo.Arguments = "-loop 1 -i \""+tbBGFrame.Text+ "\" -vf \"movie=\""+videoPath+ "\",scale=1900:-1[inner];[in][inner]overlay=70:70:shortest=1[out]\" -y \""+tempVideoPath+"\"";



the problem is inside movie parameter. i have to include video path inputed by user but its give an error because its already double quote exist before.


its successfully if i try on windows cmd like this


> cd "C:\Users\Toshiba\Pictures\test vcp\input_mp4_dir\"
> ffmpeg.exe -loop 1 -i Coronavirus00000000.jpg -vf "movie=input.mp4,scale=1180:-1[inner];[in][inner]overlay=70:70:shortest=1[out]" -y out.mp4



but how i can run that command wihtout change directory to input.mp4 directory ?

How does ffmpeg use concat of filter in C?
12 mai 2022, par JeycriIt's OK for me to use the command line like this.


ffmpeg -i test1.mp4 -i test2.mp4 -filter_complex "movie='test1.mp4',scale=640:360[v1];movie='test2.mp4',scale=640:360[v2];[v1][v2]concat" testout.mp4



This is my configuration code.


AVFilterInOut* inputs = avfilter_inout_alloc();
AVFilterInOut* outputs = avfilter_inout_alloc();
...
avfilter_graph_parse_ptr(filter->filterGraph, 
"movie='test1.mp4',scale=640:360[v1];movie='test2.mp4',scale=640:360[v2];[v1][v2]concat", 
&inputs, &outputs, NULL)
avfilter_graph_config(filter->filterGraph, NULL)



Reported error


[h264 @ 0000026dfecef780] Application has requested 17 threads. Using a thread count greater than 16 is not recommended.
[h264 @ 0000026dffae9d00] Application has requested 17 threads. Using a thread count greater than 16 is not recommended.
Output pad "default" with type video of the filter instance "in" of buffer not connected to any destination



How can I configure the filter correctly?

FFmpeg .bat file syntax
12 juillet 2022, par JeandréI have the following command for overlaying a watermark (png image) on a video. I run it from a windows .bat file and it works fine as long as I keep the png file in the same folder as my script (like this movie=easy_vacation_text.png).


%FFMPEGPATH% -i "C:\\Users\\me\\Downloads\\b2ff1bb2-3cd4-41c5-a1ee-ea6b7c066011.mp4" -y -vf "scale=1280:720 [main]; movie=easy_vacation_text.png [watermark]; [watermark]scale=1000x200 [watermark2]; [main][watermark2] overlay=(main_w/2)-(overlay_w/2):main_h-overlay_h-10 [out]" %OUTDIR%/outfile.mp4




As soon as I try to reference the png from a different folder like (like this movie=C :\Users\me\easy_vacation_text.png), it breaks :


%FFMPEGPATH% -i "C:\\Users\\me\\Downloads\\b2ff1bb2-3cd4-41c5-a1ee-ea6b7c066011.mp4" -y -vf "scale=1280:720 [main]; movie=C:\\Users\\me\\easy_vacation_text.png [watermark]; [watermark]scale=1000x200 [watermark2]; [main][watermark2] overlay=(main_w/2)-(overlay_w/2):main_h-overlay_h-10 [out]" %OUTDIR%/outfile.mp4



I tried different variations of putting quotes around the path (C :\Users\me\easy_vacation_text.png) but I can't figure out the problem.


Any ideas what I'm doing wrong ?
