Les vidéos
21 avril 2011, parComme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

FFMpeg Effect Zoom In and Zoom Out Video File
21 mars 2019, par Maxim_AI need to implement the effect of zooming in and out for video.
Two operations are needed.
The first operation is to set the zoom to zero at the beginning of the clip, and by the end of the clip the zoom was gradually increased twice.The second operation is that at the beginning of the video the zoom is equal to two, and by the end of the video the zoom should be zero.
That is, it is necessary for the zoom to increase / decrease smoothly throughout the entire duration of the video.
I know that Zoompad effect is used for this, but I could not use it for video.
Thank you all in advance for your help !

Redirecting output to different path
9 septembre 2020, par user14245857this is probably a quite easy question. I tried to solve it myself, looking at a whole bunch of different sites but couldn't find an answer.


Here it is : Change the variable "$output" so the output file of ffmpeg is written in a DIFFERENT directory than the current directory where the input files are.


Code is as follows :


$inputfiles = ls *.mxf

 foreach ($file in $inputfiles)
 
{$output = [io.path]::ChangeExtension($file, '.mp4')

 ffmpeg -i $file -map 0 -c:v libx264 -c:a aac $output}



Looking forward to your answers


Thank you very much in advance
