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 (...) -
Publier sur MédiaSpip
13 juin 2013Puis-je poster des contenus à partir d’une tablette Ipad ?
Oui, si votre Médiaspip installé est à la version 0.2 ou supérieure. Contacter au besoin l’administrateur de votre MédiaSpip pour le savoir -
Emballe médias : à quoi cela sert ?
4 février 2011, parCe plugin vise à gérer des sites de mise en ligne de documents de tous types.
Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

exec.Command error, no output to stdout or stderr
19 février 2019, par n3wtonI am trying to get the duration of a video using ffprobe and exec.Command but I keep getting an error. However, stdout and stderr are both empty so I don’t know what the problem is.
func getVideoLength(filename string) float64 {
cmd := exec.Command("ffprobe", "-i", filename, "-show_entries", "format=duration", "-v", "quiet", "-of", "csv=\"p=0\"")
fmt.Println("ffprobe", "-i", filename, "-show_entries", "format=duration", "-v", "quiet", "-of", "csv=\"p=0\"")
var out bytes.Buffer
var stderr bytes.Buffer
cmd.Stdout = &out
cmd.Stderr = &stderr
err := cmd.Run()
if err != nil {
fmt.Println("out: " + out.String())
fmt.Println("stderr: " + stderr.String())
log.Fatal(err)
}
length, err := strconv.ParseFloat(out.String(), 64)
if err != nil {
log.Fatal(err)
}
return length
}Here is the output I get :
ffprobe -i amelie.mp4 -show_entries format=duration -v quiet -of csv="p=0"
out:
stderr:
2019/02/18 21:04:39 exit status 1not very helpful.
Any ideas ?. Thanks.

Convert videos from .264 to .265 (HEVC) with ffmpeg [closed]
11 août 2024, par John TerragnoliI see that there are a few questions on this subject but I am still getting errors. All I want to do is convert videos in my library to HEVC so they take up less space.

I've tried this :


ffmpeg -i input.mp4 -c:v libx265 output.mp4



ffmpeg seems to take a long time and the output seems to be about the right size. The video will play with VLC but the icon is weird and when I try to open it with QuickTime, I get the error : 'The document “output.mov” could not be opened. The file isn’t compatible with QuickTime Player.'



I don't want to change any of the fancy settings. I just want the files to take up less space and with minimal or no quality loss.



Thanks !



EDIT : 
Having trouble keeping the time stamp that I put into the videos.

Originally I was using exiftool in terminal. But, sometimes that doesn’t work with videos, so I would airdrop them to my iPhone, use an app called Metapho to change the dates, and then airdrop them back. Exiftool was create but sometimes I just wouldn’t work. It would change the date to something like 1109212 Aug 2nd. Weird. Bottom line is that when I do these conversions, I really don’t want lose the time stamps in them.


ORIGINAL FILE THAT I TIMESTAMPED, IN .264
