Les tâches Cron régulières de la ferme
1er décembre 2010, parLa gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.

Why does my webm not work in Unity but others do ?
5 avril 2019, par UserDudeOk Im just trying to play a transparent video in Unity and Im following http://mikebrinkerink.com/2018/04/05/preparing-a-video-with-alpha-channel-for-unity/ and other tutorials.
Ive tried exporting as ProRes 444 with alpha and as Webm VP8, and using terminal ffmpeg commands. Yet when I drop the video into Unity it loads indefinitely and I have to force quit.
My file is this : https://drive.google.com/file/d/1RhOvYfeaK1rEaKdlTNcJB9EBpz4xxjvw/view?usp=sharing
And this one that I downloaded works fine : https://simpl.info/videoalpha/video/dancer1.webm
Whats the difference/how can I get mine to work ?
Log :
ffmpeg -i my_clip_with_alpha.avi -vcodec vp8 -acodec libvorbis -pix_fmt yuva420p -metadata:s:v:0 alpha_mode=”1″ -auto-alt-ref 0 my_vp8_clip_with_alpha.webm
as the command (with my clip’s name)

How to fix "Unable to find a suitable output format for '/'" error in ffmpeg running with PHP [on hold]
4 avril 2019, par C.PietroI want to compress video on the server after the upload.
I installed correctly ffmpeg and when i run from the command lineffmpeg -i input.mp4 -vcodec libx265 -crf 28 -vcodec h264 -acodec aac -strict -2 output.mp4
it works !
But if i run the same command from PHP with exec,
class VideoCompress {
function compress($path, $name){
if (`which ffmpeg`) {
exec("cd \"$path\";ffmpeg -i \"$name\" -vcodec libx265 -crf 28 -vcodec h264 -acodec aac -strict -2 \"bk_$name\" / 2>&1", $o);
print_r8($o);
}
}
}it fails and return this error
