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 (...) -

Possibilité de déploiement en ferme
12 avril 2011, parMediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...)

Code can not read property 1 of undefined [closed]
25 mai 2023, par Jesse CopasI'm a very new programmer and am working on a Tdarr plugin in JS.
Everything works fine until a 4k file tries to get transcoded and it fails with this log


2023-05-24T19:09:54.906Z ZoBKWMMKG:Node\[hidden-hog\]:Worker\[tall-tuna\]:{"pluginInputs":{"BitRate":"4000","ResolutionSelection":"1080p","Container":"mkv","AudioType":"AAC","FrameRate":"24"}}

2023-05-24T19:09:54.907Z ZoBKWMMKG:Node\[hidden-hog\]:Worker\[tall-tuna\]:Error TypeError: Cannot read property '1' of undefined


It's saying that it's unable to read property 1 of undefined and I'm looked and looked and looked and can't find what it is referring to. Hoping to get another set of eyes on it
The plugin Code is here

Tried transcoding 4k files down to 1080p but it fails due to that undefined error. All Res 1080p and lower that I have tried work correctly

17 mai 2023, par Mulham DarwishI build this flask app to live stream security cameras and the live stream works with the screenshot function but when start recording it crash but few times same code it worked and saved the video here the code. with the html file using js.

Mingw-w64 - printf does not work
27 décembre 2013, par Gosha U.First I wanted to modificate ffplay according to my requirments. Then I noticed that original ffplay from my build can't play some video files, but it didn't write any message to console. Then I noticed that ffmpeg also don't write any usage message when I run it without params. But it works. If I run it from terminal it's like running asynchronously ! The terminal just shows next row. I mean it asks for a next command. But the
ffmpegprocess is visible in task manager and it writes the output video file what I had requested !I created following souce file. I have modified the Makefile. So it have built the exe-file works just the same way. I have no idea how it can be.
#include
#include "cmdutils.h"
const char program_name[] = "hello";
const int program_birth_year = 2013;
void show_help_default(const char *opt, const char *arg)
{
printf("zxcvbnm\n");
}
int main(int argc, char **argv)
{
printf("1234567890\n");
return 0;
}And after that I created real hello world app with MinGW-w64 and qmake without eny extra libs. And its printf does not work.
I want to prevent this behavior.
I want to make printf working in traditional manner.
How I build FFmpeg :
