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.

Extract undecoded audio payload from song file ?
6 juin 2012, par DataSurferWhat tools are available to extract the raw undecoded audio payload from a song file ?
I am looking for a solution that will work on wma, m4a, mp3, and ogg files.
One of the purposes is to be able to calculate the md5sum of the audio payload.
I tried
ffmpeg -i <song file="file"> -f md5 -</song>
but this actually does a decoding pass which is not desired. Also this seems to produce different results depending on the versions of the decoders in use.I tried
ffmpeg -i <song file="file"> -acodec copy - > <raw payload="payload" file="file"></raw></song>
but ffmpeg complains that it does not know the desired output format even thoughcopy
is explicitly specified.I've tried various incarnations of
-map_metadata -1
but the documentation is obtuse at best.In the end the ideal is to have an stdout of the raw UNdecoded audio portion of a song file.
Any ideas ?

Extract Thumbnails of Every Camera Change on a Video File
8 juillet 2013, par Henry MazzaIs there a way to detect and extract thumbnails of every sudden change (camera change, slide change, scene change, got it ?) of a video file (preferably h264).
Something in the lines of comparing keyframes and look for differences larger than some given constant.
