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" (...)

apetag : Fix APE tag size check
16 septembre 2014, par Katerina Barone-Adesiapetag : Fix APE tag size check
The size variable is (correctly) unsigned, but is passed to several functions
which take signed parameters, such as avio_read, sometimes after having
numbers added to it. So ensure that size remains within the bounds that
these functions can handle.CC : libav-stable@libav.org

image sequence to Video. Faster Way to Render "Hold" frames in FFMPEG (without duplicating image)
11 septembre 2014, par dprogramzI’m working on a project that converts a Flash Movie with dynamic input to Apple Animation Codec.
It’s to generate messaging, so there is some animation, then the message holds, then animation resumes, etc. The hold times are user variable.
I’m first converting the SWF to PNGs by sending a bitstream via the actionscript3 PNGEncoder library, and using a PHP script to save the bitstream to the server as a series of temp png files. This is working very fast.
from flash ill get an image sequence like this :
frame000.png-frame014.png
frame0200.png-frame250.png
frame350.png-frame400.png
frames 15-199 are all the same image holding. I’m not sending bitstreams for the holding images to save bandwidth and time, it would be redundant to send the same image file 185 times. Right now I am copying frame14.png with incrementing file numbers. I have to do this for each instance there is a hold frame.
After all the hold frame holes are filled I then run FFMPEG on the complete image sequence to generate the video.
Is there any faster way to do this ? The longer the hold (which is variable by the user) the longer it takes to render. I understand that there will be some extra render time, but it’s a repeated image and in other conversion programs does not take nearly as long. Or is my current way of doing it the only way in this instance ?
When rendering out of a program like after effects, the animation codec seems to dynamically adjust the frame rate for hold frames.
Thanks for the help and insight !!

Audio not working with FFMPEG conversion
17 juillet 2017, par mikelbringI am trying to convert an avi file to flv with an fairly simple ffmpeg command :
ffmpeg -i dbkai12.avi -ab 96k -b 700k -ar 44100 -s 640x480 -acodec mp3 video.flv
The video does exactly what I want, just no audio. I didnt come up with these numbers, just pulled them from different sources.
Also tried :
ffmpeg -i video.avi -ar 22050 -ab 32 -f flv -s 320x240 video.flv
Same result.
