Creating farms of unique websites

13 avril 2011, par kent1

MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

ffmpeg sdl output framerate too high

1er juillet 2015, par dkrikun

I’m using the following command-line to play a video via SDL :

ffmpeg -i input.mkv -f sdl "Video"

The video is being played too fast, ffmpeg prints that the framerate is 500 (not constant, just playing as fast as possible)
I’ve tried to limit the framerate as follows, but none of this has any effect :

ffmpeg -i input.mkv -r 25 -f sdl "Video"  

ffmpeg -i input.mkv -f sdl -r 25 "Video"  

ffmpeg -i input.mkv -framerate 25 -f sdl "Video"  

ffmpeg -i input.mkv -f sdl -framerate 25 "Video"

I’m using ffmpeg version ffmpeg-20150605-git-7be0f48-win64-static on Windows 7.
ffplay input.mkv works pretty well.

Thank you !

EDIT : console output for ffmpeg -i input.mkv -r 25 -f sdl "Video" follows :

FFmpeg can't access file in Dropbox on Ubuntu 12.04

30 juin 2015, par afterglowlee
I have installed FFmpeg on Ubuntu 12.04. When I use ffmpeg -i command to check some video file online, it works :
```
ffmpeg -i http://techslides.com/demos/sample-videos/small.mp4
```
However, when I check a public file hosted in my Dropbox it gives ’No such file or directory error’ :
```
ffmpeg -i https://dl.dropboxusercontent.com/u/51617581/bigbuck.webm
```
and the error is :

https://dl.dropboxusercontent.com/u/51617581/bigbuck.webm : No such
file or directory

and here is the version info of the ffmpeg installation :

ffmpeg version 0.8.17-4:0.8.17-0ubuntu0.12.04.1, Copyright (c)
2000-2014 the Libav developers built on Mar 16 2015 13:26:50 with
gcc 4.6.3

I have also tried both files on my Mac 10.10 laptop, and both of them work fine. Could anyone suggest where is the problem ? Many thanks.
