Creating farms of unique websites
13 avril 2011, parMediaSPIP 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" (...) -
Other interesting software

The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...

How to optimize video to animated GIF conversion using PHP + shell commands
15 mars 2012, par user1070798I have a web application that converts any video into an animated GIF. The app runs in PHP and the following steps are executed through php's shell_exec :
- Scale video to smaller dimensions, if they are large (ffmpeg -i $in -s 200x150 -an $out)
- Use ffmpeg to extract 1 jpeg every x seconds (ffmpeg -i $in -ss $ss -vframes 1 $out)
-
Convert jpegs to animated GIF using imagick (convert -delay $delay -loop 0 $dir/* $out)
aside - the reason I don't use the ffmpeg gif89a output is because the quality sucks.
I want to be able to except any major image format, but the most common will probably be .flv (flash) and .avi/.mpg.
My application runs fine, but I am a perfectionist and it needs to be faster for scalability.
My web server has 16 cores and I would like to utilize them as much as possible, but .flv multi-threading appears to not be supported by ffmpeg, while .avi and some others are supported. Also, ffmpeg doesn't support multi-threading when outputting to jpegs.
Does anyone know of any other programs that support multi-threading for .flv and others ? Are there any more efficient methods to create an animated GIF from video, while maintaining relatively decent quality (aka not the 100-color palette that ffmpeg supports) ?
Also, if anyone knows which codecs might perform best for stages 1 and 2, particularly with flv, I'd love to know. I've done hours of testing, but there are just so many options I haven't come to any solid conclusions.
***Update : My online app is working well so far animated gif generator. I would still love to make it faster though, so if anyone has run into similar circumstances... let me know !
