Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur

8 février 2011, par kent1

La visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

How to stream MJPEG stream to RTMP server ?

24 octobre 2018, par geooot

I have a MJPEG stream and I’m trying to use ffmpeg to take it as an input and stream it to an rtmp server at a defined framerate.

I have already tried this as a command :

ffmpeg -f mjpeg -r 60 -i http://localhost:3030/ -f flv -vcodec flv rtmp://localhost/live/test

While ffmpeg looks like it is sending something...

I cannot preview the stream through VLC. Weirdly enough, if I let VLC try to load the url (rtmp ://localhost/live/test) and then close ffmpeg, VLC will actually show the video stream for a few frames and then stop again.

Help on how to achieve this would be much appreciated.

Unable to play video processed by ffmpeg

8 janvier 2023, par Kong

I have an issue of not being able to play a video that was processed by ffmpeg. I have 6 videos, each of different length but same frame rate that i merge (2 rows 3 columns).

VLC player doesn't run it, using any other players return an error. Below is the code I used to combine the videos. I can't seem to find a solution on Google or Stack Overflow.

Streaming trouble, ffmpeg unable to find a suitable output format

9 octobre 2018, par Michael Munyanyi

FFMPEG for some odd reason won’t allow me to output a stream, it’s odd because I have two computers available and one, which had low CPU was having trouble decoding but the stream worked, so I switched my network cables and I have tried transcoding with the same command and it will not output a stream.

My command reads

ffmpeg -i udp://@xxx.x.x.xx.xxxx -f mpegts udp://@xxx.x.x.xx.xxxx

I also tried

ffmpeg -i udp://@xxx.x.x.xx.xxxx udp://@xxx.x.x.xx.xxxx

The error reads

[NULL @ 000001c95eeb2600] Unable to find a suitable output format for udp://@xxx.x.x.xx.xxxx'

udp://@xxx.x.x.xx.xxxx: Invalid argument"
